transport type

transport type. TCP, UDP 혹은 WebSocket 과 같은 프로토콜이나 TLS/SSL 과 같은 암호화를 설정한다.

Example

Basic UDP transport

[transport-udp]
type=transport
protocol=udp    ;udp,tcp,tls,ws,wss
bind=0.0.0.0

UDP transport behind NAT

[transport-udp-nat]
type=transport
protocol=udp
bind=0.0.0.0
local_net=192.0.2.0/24
external_media_address=203.0.113.1
external_signaling_address=203.0.113.1

Basic IPv6 UDP tranport

[transport-udp-ipv6]
type=transport
protocol=udp
bind=::

Exmple IPv4 TLS transport

[transport-tls]
type=transport
protocol=tls
bind=0.0.0.0
cert_file=/path/mycert.crt
priv_key_file=/path/mykey.key
cipher=ADH-AES256-SHA,ADH-AES128-SHA
method=tlsv1

registration type

Example

outbound registration with outbound authentication

This is a simple registration that works with some SIP trunking providers.

You'll need to set up the auth example "mytrunk_auth" below to enable outbound authentication. Note that we "outbound_auth=" use for outbound authentication instead of "auth=", which is for inbound authentication.

If you are registering to a server from behind NAT, be sure you assign a transport that is appropriately configured with NAT related settings. See the NAT transport example.

"contact_user=" sets the SIP contact header's user portion ofthe SIP URI this will affect the extension reached in dialplan when the far end calls you at this registration. The default is 's'.

If you would like to enable line support and have incoming calls related wo this registration to to an endpoint automatically the "line" and "endpoint" options must be set. The "endpoint" option specifies what endpoint the incoming call should be associated with.

[mytrunk]
type=registration
transport=transport-udp
outbound_auth=mytrunk_auth
server_uri=sip:sip.example.com
client_uri=sip:1234567890@sip.example.com
contact_user=1234567890
retry_interval=60
forbidden_retry_interval=600
expiration=3600
line=yes
endpoint=mytrunk

[mytrunk_auth]
type=auth
auth_type=userpass
password=1234567890
username=1234567890
realm=sip.example.com

endpoint type

Options

• rtp_symmetric=no

Enforce that RTP must be symmetric. Send media to the address and port from which Asterisk receives it, regardless of where SDP indicates that it should be sent. (default: "no")

• force_rport

Send responses to the source IP address and port as though port were present, even if it's not.

• rewrite_contact

Rewrite SIP Contact to the source address and port of the request so that subsequent requests go to that address and port.

username=6001

AOR(Address of Record)

Example

Create automatic contact objects.

[6001]
type=aor
max_contacts=1

Create manual contact objects.

[6001]
type=aor
contact=sip:6001@192.0.2.1:5060

It's useful to note that you could define only the domain and omit the user portion of the SIP URI ifyou wanted. Then you could define the user portion dynamically in your dialplan when calling the Dial application. You'll likely do this when building an AOR/Endpoint combo to use for dialing out to an ITSP. For example: "Dial(PJSIP/${EXTEN}@mytrunk)"

[mytrunk]
type=aor
contact=sip:203.0.113.1:5060

Sample

; PJSIP Configuration Samples and Quick Reference
;
; This file has several very basic configuration examples, to serve as a quick
; reference to jog your memory when you need to write up a new configuration.
; It is not intended to teach PJSIP configuration or serve as an exhaustive
; reference of options and potential scenarios.
;
; This file has two main sections.
; First, manually written examples to serve as a handy reference.
; Second, a list of all possible PJSIP config options by section. This is
; pulled from the XML config help. It only shows the synopsis for every item.
; If you want to see more detail please check the documentation sources
; mentioned at the top of this file.

; ============================================================================
; NOTICE NOTICE NOTICE NOTICE NOTICE NOTICE NOTICE NOTICE NOTICE NOTICE
;
; This file does not maintain the complete option documentation.
; ============================================================================

; Documentation
;
; The official documentation is at http://wiki.asterisk.org
; You can read the XML configuration help via Asterisk command line with
; "config show help res_pjsip", then you can drill down through the various
; sections and their options.
;

;========!!!!!!!!!!!!!!!!!!!  SECURITY NOTICE  !!!!!!!!!!!!!!!!!!!!===========
;
; At a minimum please read the file "README-SERIOUSLY.bestpractices.txt",
; located in the Asterisk source directory before starting Asterisk.
; Otherwise you risk allowing the security of the Asterisk system to be
; compromised. Beyond that please visit and read the security information on
; the wiki at: https://wiki.asterisk.org/wiki/x/EwFB
;
; A few basics to pay attention to:
;
; Anonymous Calls
;
; By default anonymous inbound calls via PJSIP are not allowed. If you want to
; route anonymous calls you'll need to define an endpoint named "anonymous".
; res_pjsip_endpoint_identifier_anonymous.so handles that functionality so it
; must be loaded. It is not recommended to accept anonymous calls.
;
; Access Control Lists
;
; See the example ACL configuration in this file. Read the configuration help
; for the section and all of its options. Look over the samples in acl.conf
; and documentation at https://wiki.asterisk.org/wiki/x/uA80AQ
; If possible, restrict access to only networks and addresses you trust.
;
; Dialplan Contexts
;
; When defining configuration (such as an endpoint) that links into
; dialplan configuration, be aware of what that dialplan does. It's easy to
; accidentally provide access to internal or outbound dialing extensions which
; could cost you severely. The "context=" line in endpoint configuration
; determines which dialplan context inbound calls will enter into.
;
;=============================================================================

; Overview of Configuration Section Types Used in the Examples
;
; * Transport "transport"
;   * Configures res_pjsip transport layer interaction.
; * Endpoint "endpoint"
;   * Configures core SIP functionality related to SIP endpoints.
; * Authentication "auth"
;   * Stores inbound or outbound authentication credentials for use by trunks,
;     endpoints, registrations.
; * Address of Record "aor"
;   * Stores contact information for use by endpoints.
; * Endpoint Identification "identify"
;   * Maps a host directly to an endpoint
; * Access Control List "acl"
;   * Defines a permission list or references one stored in acl.conf
; * Registration "registration"
;   * Contains information about an outbound SIP registration
; * Resource Lists
;   * Contains information for configuring resource lists.
; * Phone Provisioning "phoneprov"
;   * Contains information needed by res_phoneprov for autoprovisioning

; The following sections show example configurations for various scenarios.
; Most require a couple or more configuration types configured in concert.

;=============================================================================

; Naming of Configuration Sections
;
; Configuration section names are denoted with enclosing brackets,
; e.g. [6001]
; In most cases, you can name a section whatever makes sense to you. For example
; you might name a transport [transport-udp-nat] to help you remember how that
; section is being used. However, in some cases, ("endpoint" and "aor" types)
; the section name has a relationship to its function.
;
; Depending on the modules loaded, Asterisk can match SIP requests to an
; endpoint or aor in a few ways:
;
; 1) Match a section name for endpoint type sections to the username in the
;    "From" header of inbound SIP requests.
; 2) Match a section name for aor type sections to the username in the "To"
;    header of inbound SIP REGISTER requests.
; 3) With an identify type section configured, match an inbound SIP request of
;    any type to an endpoint or aor based on the IP source address of the
;    request.
;
; Note that sections can have the same name as long as their "type" options are
; set to different values. In most cases it makes sense to have associated
; configuration sections use the same name, as you'll see in the examples within
; this file.

;===============EXAMPLE TRANSPORTS============================================
;
; A few examples for potential transport options.
;
; For the NAT transport example, be aware that the options starting with
; the prefix "external_" will only apply to communication with addresses
; outside the range set with "local_net=".
;
; You can have more than one of any type of transport, as long as it doesn't
; use the same resources (bind address, port, etc) as the others.

; Basic UDP transport
;
;[transport-udp]
;type=transport
;protocol=udp    ;udp,tcp,tls,ws,wss
;bind=0.0.0.0

; UDP transport behind NAT
;
;[transport-udp-nat]
;type=transport
;protocol=udp
;bind=0.0.0.0
;local_net=192.0.2.0/24
;external_media_address=203.0.113.1
;external_signaling_address=203.0.113.1

; Basic IPv6 UDP transport
;
;[transport-udp-ipv6]
;type=transport
;protocol=udp
;bind=::

; Example IPv4 TLS transport
;
;[transport-tls]
;type=transport
;protocol=tls
;bind=0.0.0.0
;cert_file=/path/mycert.crt
;priv_key_file=/path/mykey.key
;cipher=ADH-AES256-SHA,ADH-AES128-SHA
;method=tlsv1


;===============OUTBOUND REGISTRATION WITH OUTBOUND AUTHENTICATION============
;
; This is a simple registration that works with some SIP trunking providers.
; You'll need to set up the auth example "mytrunk_auth" below to enable outbound
; authentication. Note that we "outbound_auth=" use for outbound authentication
; instead of "auth=", which is for inbound authentication.
;
; If you are registering to a server from behind NAT, be sure you assign a transport
; that is appropriately configured with NAT related settings. See the NAT transport example.
;
; "contact_user=" sets the SIP contact header's user portion of the SIP URI
; this will affect the extension reached in dialplan when the far end calls you at this
; registration. The default is 's'.
;
; If you would like to enable line support and have incoming calls related to this
; registration go to an endpoint automatically the "line" and "endpoint" options must
; be set. The "endpoint" option specifies what endpoint the incoming call should be
; associated with.

;[mytrunk]
;type=registration
;transport=transport-udp
;outbound_auth=mytrunk_auth
;server_uri=sip:sip.example.com
;client_uri=sip:1234567890@sip.example.com
;contact_user=1234567890
;retry_interval=60
;forbidden_retry_interval=600
;expiration=3600
;line=yes
;endpoint=mytrunk

;[mytrunk_auth]
;type=auth
;auth_type=userpass
;password=1234567890
;username=1234567890
;realm=sip.example.com

;===============ENDPOINT CONFIGURED AS A TRUNK, OUTBOUND AUTHENTICATION=======
;
; This is one way to configure an endpoint as a trunk. It is set up with
; "outbound_auth=" to enable authentication when dialing out through this
; endpoint. There is no inbound authentication set up since a provider will
; not normally authenticate when calling you.
;
; The identify configuration enables IP address matching against this endpoint.
; For calls from a trunking provider, the From user may be different every time,
; so we want to match against IP address instead of From user.
;
; If you want the provider of your trunk to know where to send your calls
; you'll need to use an outbound registration as in the example above this
; section.
;
; NAT
;
; At a basic level configure the endpoint with a transport that is set up
; with the appropriate NAT settings. There may be some additional settings you
; need here based on your NAT/Firewall scenario. Look to the CLI config help
; "config show help res_pjsip endpoint" or on the wiki for other NAT related
; options and configuration. We've included a few below.
;
; AOR
;
; Endpoints use one or more AOR sections to store their contact details.
; You can define multiple contact addresses in SIP URI format in multiple
; "contact=" entries.
;

;[mytrunk]
;type=endpoint
;transport=transport-udp
;context=from-external
;disallow=all
;allow=ulaw
;outbound_auth=mytrunk_auth
;aors=mytrunk
;                   ;A few NAT relevant options that may come in handy.
;force_rport=yes    ;It's a good idea to read the configuration help for each
;direct_media=no    ;of these options.
;ice_support=yes

;[mytrunk]
;type=aor
;contact=sip:198.51.100.1:5060
;contact=sip:198.51.100.2:5060

;[mytrunk]
;type=identify
;endpoint=mytrunk
;match=198.51.100.1
;match=198.51.100.2


;=============ENDPOINT CONFIGURED AS A TRUNK, INBOUND AUTH AND REGISTRATION===
;
; Here we are allowing a remote device to register to Asterisk and requiring
; that they authenticate for registration and calls.
; You'll note that this configuration is essentially the same as configuring
; an endpoint for use with a SIP phone.


;[7000]
;type=endpoint
;context=from-external
;disallow=all
;allow=ulaw
;transport=transport-udp
;auth=7000
;aors=7000

;[7000]
;type=auth
;auth_type=userpass
;password=7000
;username=7000

;[7000]
;type=aor
;max_contacts=1


;===============ENDPOINT CONFIGURED FOR USE WITH A SIP PHONE==================
;
; This example includes the endpoint, auth and aor configurations. It
; requires inbound authentication and allows registration, as well as references
; a transport that you'll need to uncomment from the previous examples.
;
; Uncomment one of the transport lines to choose which transport you want. If
; not specified then the default transport chosen is the first compatible transport
; in the configuration file for the contact URL.
;
; Modify the "max_contacts=" line to change how many unique registrations to allow.
;
; Use the "contact=" line instead of max_contacts= if you want to statically
; define the location of the device.
;
; If using the TLS enabled transport, you may want the "media_encryption=sdes"
; option to additionally enable SRTP, though they are not mutually inclusive.
;
; If this endpoint were remote, and it was using a transport configured for NAT
; then you likely want to use "direct_media=no" to prevent audio issues.


;[6001]
;type=endpoint

;===============ENDPOINT BEHIND NAT OR FIREWALL===============================
;
; This example assumes your transport is configured with a public IP and the
; endpoint itself is behind NAT and maybe a firewall, rather than having
; Asterisk behind NAT. For the sake of simplicity, we'll assume a typical
; VOIP phone. The most important settings to configure are:
;
;  * direct_media, to ensure Asterisk stays in the media path
;  * rtp_symmetric and force_rport options to help the far-end NAT/firewall
;
; Depending on the settings of your remote SIP device or NAT/firewall device
; you may have to experiment with a combination of these settings.
;
; If both Asterisk and the remote phones are a behind NAT/firewall then you'll
; have to make sure to use a transport with appropriate settings (as in the
; transport-udp-nat example).
;

;============EXAMPLE ACL CONFIGURATION==========================================
;
; The ACL or Access Control List section defines a set of permissions to permit
; or deny access to various address or addresses. Alternatively it references an
; ACL configuration already set in acl.conf.
;
; The ACL configuration is independent of individual endpoint configuration and
; operates on all inbound SIP communication using res_pjsip.

; Reference an ACL defined in acl.conf.
;
;[acl]
;type=acl
;acl=example_named_acl1

; Reference a contactacl specifically.
;
;[acl]
;type=acl
;contact_acl=example_contact_acl1

; Define your own ACL here in pjsip.conf and
; permit or deny by IP address or range.
;
;[acl]
;type=acl
;deny=0.0.0.0/0.0.0.0
;permit=209.16.236.0/24
;deny=209.16.236.1

; Restrict based on Contact Headers rather than IP.
; Define options multiple times for various addresses or use a comma-delimited string.
;
;[acl]
;type=acl
;contact_deny=0.0.0.0/0.0.0.0
;contact_permit=209.16.236.0/24
;contact_permit=209.16.236.1
;contact_permit=209.16.236.2,209.16.236.3

; Restrict based on Contact Headers rather than IP and use
; advanced syntax. Note the bang symbol used for "NOT", so we can deny
; 209.16.236.12/32 within the permit= statement.
;
;[acl]
;type=acl
;contact_deny=0.0.0.0/0.0.0.0
;contact_permit=209.16.236.0
;permit=209.16.236.0/24, !209.16.236.12/32


;============EXAMPLE RLS CONFIGURATION==========================================
;
;Asterisk provides support for RFC 4662 Resource List Subscriptions. This allows
;for an endpoint to, through a single subscription, subscribe to the states of
;multiple resources. Resource lists are configured in pjsip.conf using the
;resource_list configuration object. Below is an example of a resource list that
;allows an endpoint to subscribe to the presence of alice, bob, and carol.

;[my_list]
;type=resource_list
;list_item=alice
;list_item=bob
;list_item=carol
;event=presence

;The "event" option in the resource list corresponds to the SIP event-package
;that the subscribed resources belong to. A resource list can only provide states
;for resources that belong to the same event-package. This means that you cannot
;create a list that is a combination of presence and message-summary resources,
;for instance. Any event-package that Asterisk supports can be used in a resource
;list (presence, dialog, and message-summary). Whenever support for a new event-
;package is added to Asterisk, support for that event-package in resource lists
;will automatically be supported.

;The "list_item" options indicate the names of resources to subscribe to. The
;way these are interpreted is event-package specific. For instance, with presence
;list_items, hints in the dialplan are looked up. With message-summary list_items,
;mailboxes are looked up using your installed voicemail provider (app_voicemail
;by default). Note that in the above example, the list_item options were given
;one per line. However, it is also permissible to provide multiple list_item
;options on a single line (e.g. list_item = alice,bob,carol).

;In addition to the options presented in the above configuration, there are two
;more configuration options that can be set.
; * full_state: dictates whether Asterisk should always send the states of
;   all resources in the list at once. Defaults to "no". You should only set
;   this to "yes" if you are interoperating with an endpoint that does not
;   behave correctly when partial state notifications are sent to it.
; * notification_batch_interval: By default, Asterisk will send a NOTIFY request
;   immediately when a resource changes state. This option causes Asterisk to
;   start batching resource state changes for the specified number of milliseconds
;   after a resource changes states. This way, if multiple resources change state
;   within a brief interval, Asterisk can send a single NOTIFY request with all
;   of the state changes reflected in it.

;There is a limitation to the size of resource lists in Asterisk. If a constructed
;notification from Asterisk will exceed 64000 bytes, then the message is deemed
;too large to send. If you find that you are seeing error messages about SIP
;NOTIFY requests being too large to send, consider breaking your lists into
;sub-lists.

;============EXAMPLE PHONEPROV CONFIGURATION================================

; Before configuring provisioning here, see the documentation for res_phoneprov
; and configure phoneprov.conf appropriately.

; For each user to be autoprovisioned, a [phoneprov] configuration section
; must be created.  At a minimum, the 'type', 'PROFILE' and 'MAC' variables must
; be set.  All other variables are optional.
; Example:

;[1000]
;type=phoneprov               ; must be specified as 'phoneprov'
;endpoint=1000                ; Required only if automatic setting of
                              ; USERNAME, SECRET, DISPLAY_NAME and CALLERID
                              ; are needed.
;PROFILE=digium               ; required
;MAC=deadbeef4dad             ; required
;SERVER=myserver.example.com  ; A standard variable
;TIMEZONE=America/Denver      ; A standard variable
;MYVAR=somevalue              ; A user confdigured variable

; If the phoneprov sections have common variables, it is best to create a
; phoneprov template.  The example below will produce the same configuration
; as the one specified above except that MYVAR will be overridden for
; the specific user.
; Example:

;[phoneprov_defaults](!)
;type=phoneprov               ; must be specified as 'phoneprov'
;PROFILE=digium               ; required
;SERVER=myserver.example.com  ; A standard variable
;TIMEZONE=America/Denver      ; A standard variable
;MYVAR=somevalue              ; A user configured variable

;[1000](phoneprov_defaults)
;endpoint=1000                ; Required only if automatic setting of
                              ; USERNAME, SECRET, DISPLAY_NAME and CALLERID
                              ; are needed.
;MAC=deadbeef4dad             ; required

                    ; Which becomes this: "1235557890"
                    ;
                    ; Note: The caller-id and redirecting number strings obtained
                    ; from incoming SIP URI user fields are always truncated at the
