Overview
Asterisk sip.conf 문서 설명
general section
SIP Configuration - general The [general] section of sip.conf includes the following variables:
allowsubscribe = yes|no : Allow or Ignore Subscribe requests
allow = <codec> : Allow codecs in order of preference (Use DISALLOW=ALL first, before allowing other codecs)
disallow = all : Disallow all codecs (global configuration)
Asterisk sip allowexternaldomains = yes|no : Enable/Disable INVITE and REFER to non-local domains. Default yes. (New in v1.2.x).
allowguest = yes|no : Allow or reject guest calls. Default is yes. (this can also be set to 'osp' if asterisk was compiled with OSP support). (New in v1.2.x).
Asterisk sip allowoverlap = yes|no : Enable/disable overlap dialing support. Default yes (Overlap dial provides for a longer time-out period between digits, also called the inter-digit timer. With overlap dial set to off, the gateway expects to receive the digits one right after the other coming in to this line with very little delay between digits. With overlap dial set to on, then the device waits up to about 2 seconds between digits).
autocreatepeer = yes|no : If set, anyone will be able to log in as a peer (with no check of credentials; useful for operation with SER). Default no.
Asterisk sip autodomain = yes|no : Enable/disable Asterisk's ability to add local hostnames and local IP address to the domain list. externip or externhost are also taken into the domain list. Default no. (New in v1.2.x).
bindaddr = IP_Address : IP Address to bind to (listen on). Default 0.0.0.0 (all network interfaces).
bindport = Number : UDP Port to bind to (listen on). Used to be port in Asterisk v1.0.x. Default 5060.
callerid = <string> : Caller ID information used when nothing else is available. Defaults to asterisk. (The ability to override the default appears to available in Asterisk 1.0.9. Unsure about other versions.)
canreinvite = update|yes|no|nonat (global setting): For some reason this defaults to yes, so beware...
Asterisk sip checkmwi = Number : Global interval (in seconds) between mailbox checks. Default 10 seconds. (New in v1.2.x)
Asterisk sip compactheaders = yes|no : Indicates Asterisk should send compact (i.e. abbreviated) headers in the SIP messages. Default no. (New in v1.2.x)
context = <contextname> : This is the default context and is used when a endpoint has no context property. The context in section of an endpoint is used to route calls from that endpoint to the wanted destination. The context body is located in extensions.conf.

externip = IP_Address or a hostname : Address that we're going to put in SIP messages if we're behind a NAT. If a hostname is used as the value, then the IP address associated with the hostname is looked up only once during the reading of the sip.conf. If you want support for a hostname associated with a dynamic IP address, use Asterisk sip externhost.
externhost = hostname.tld : (New in Asterisk 1.2.x)
externrefresh = Number : Specify how often (in seconds) a hostname DNS lookup should be performed for the value entered in 'externhost'. Default 10 seconds. (New in Asterisk 1.2.x).

jbenable = yes|no : Enables the use of a jitterbuffer on the receiving side of a SIP channel. (Added in Version 1.4)
jbforce = yes|no : Forces the use of a jitterbuffer on the receive side of a SIP channel. Defaults to "no". (Added in Version 1.4)
jbmaxsize = Number : Max length of the jitterbuffer in milliseconds. (Added in Version 1.4)
jbresyncthreshold = Number : Jump in the frame timestamps over which the jitterbuffer is resynchronized. Useful to improve the quality of the voice, with big jumps in/broken timestamps, usually sent from exotic devices and programs. Defaults to 1000. (Added in Version 1.4)
jbimpl = fixed|adaptive: Jitterbuffer implementation, used on the receiving side of a SIP channel. Two implementations are currently available - "fixed" (with size always equals to jbmaxsize) and "adaptive" (with variable size, actually the new jb of IAX2). Defaults to fixed. (Added in Version 1.4)

callevents = yes|no: Set to yes to receive events on AMI when a call is put on/off hold.
disallowed_methods= (1.8.x) When a dialog is started with another SIP endpoint, the other endpoint should include an Allow header telling us what SIP methods the endpoint implements. However, some endpoints either do not include and Allow header or lie about what methods they implement. In the former case, Asterisk makes the assumption that the endpoint supports all known SIP methods. If you know that your SIP endpoint does not provide support for a specific method, then you may provide a comma-separated list of methods that your endpoint does not implement in the disallowed_methods option. Note that if your endpoint is truthful with its Allow header, then there is no need to set this option. This option may be set in the general section or may be set per endpoint. If this option is set both in the general section and in a peer section, then the peer setting completely overrides the general setting (i.e. the result is *not* the union of the two options). Note also that while Asterisk currently will parse an Allow header to learn what methods an endpoint supports, the only actual use for this currently is for determining if Asterisk may send connected line UPDATE requests. Its use may be expanded in the future.
preferred_codec_only= (1.8.x) Respond to a SIP invite with the single most preferred codec rather than advertising all joint codec capabilities. This limits the other side's codec choice to exactly what we prefer.
engine= (1.8.x) RTP engine to use when communicating with the device
peers
SIP configurations - peers and clients These variables can be configured for each SIP peer definition:
(If not specified, the configuration variable can be used for both type=peer and type=user.)

call-limit = number : Number of simultaneous calls through this user/peer.
callgroup = num1,num2-num3 : Defines call groups for calls to this device.
callingpres = number|descriptive_text : Set Caller-ID presentation on a call. Valid descriptive values are: allowed_not_screened, allowed_passed_screen, allowed_failed_screen, allowed, prohib_not_screened, prohib_passed_screen, prohib_failed_screen, prohib, and unavailable. See SetCallerPres for more information. Default allowed_not_screened.
canreinvite = update|yes|no|nonat : If the client is able to support SIP re-invites. Default yes.
cid_number = <string> : On incoming (through this peer) calls sets the outbound $CALLERID(num) to <string>. (New in v.1.4.x)
context = <context_name> : If type=user, the Context for the inbound call from this SIP user definition. If type=peer, the Context in the dialplan for outbound calls from this SIP peer definition. If type=friend the context used for both inbound and outbound calls through the SIP entities definition. If no type=user entry matches an inbound call, then a type=peer or type=friend will match if the hostname or IP address
defined in host= matches.
defaultip = Dotted.Quad.IP.Addr : Default IP address of client if host=dynamic is specified. Used if client has not registered at any other IP address. Valid only for type=peer.
defaultuser = The new name for the 'username' variable.

dtmfmode = inband|info|rfc2833 : How the client handles DTMF signalling. Default rfc2833. Warning: inband very high CPU load.
fromuser = <from_ID> : Specify user to put in "from" instead of $CALLERID(number) (overrides the callerid) when placing calls _to_ peer (another SIP proxy). Valid only for type=peer.
fromdomain = <domain> : Sets default From: domain in SIP messages when placing calls _to_ peer. Valid only when in [general] section or type=peer.
fullcontact = <sip:uri_contact> : SIP URI contact for realtime peer. Valid only for realtime peers.
fullname = "Full Name" : Sets outbound $CALLERID(name). (New in v1.4.x)
host = dynamic|hostname|IPAddr : How to find the client - IP # or host name. If you want the phone to register itself, use the keyword dynamic instead of Host IP.
incominglimit and outgoinglimit = Number : Limits for number of simultaneous active calls for a SIP client. Valid only for type=peer.
insecure : very|yes|no|invite|port : Specifies how to handle connections with peers. Default no (authenticate all connections). invite and port added in v1.2.x, yes and very removed in v1.6.x, possible to use multiple options separated by commas from v1.4.x

mailbox = mailbox : Voicemail extension (for message waiting indications). Valid only for type=peer. Edit: also valid for type=friend (verified with 1.4.22.1).
md5secret : MD5-Hash of "<user>:==SIP_realm==:<secret>" (can be used instead of secret). Default for authenticating to an Asterisk server when SIP realm is not explicitly declared is "<user>:asterisk:<secret>".
musicclass = one of the classes specified in musiconhold.conf
musiconhold = Set class of musiconhold on calls from SIP phone. Calls to the phone require SetMusicOnHold cmd of higher priority (lower numerical value of priority) than Dial cmd in dialplan in order to set this class for the call. Calls have the MusicOnHold class set on a per call basis, not on a per phone basis, and making a call through any extension specifying SetMusicOnHold will override this value for the call.
subscribemwi: Instructs Asterisk to not send NOTIFY messages for message waiting indication (added in v1.4)
name = <name> : Name of the realtime peer. If the peer is an actual phone then this will generally be the extension number of that phone. On some softphones this field corresponds to the "username" field/option in the softphone's settings. Valid only for realtime peers.
nat = yes|no : This variable changes the behaviour of Asterisk for clients behind a firewall. This does not solve the problem if Asterisk is behind the firewall and the client on the outside. Please note that Asterisk 1.0.x nat can now have the values: yes|no|never|route; Asterisk 1.8 can have the values: yes|no|force_rport|comedia. Default no which really means to use rfc3581 techniques.
outboundproxy = IP_address or DNS SRV name (excluding the _sip._udp prefix) : SRV name, hostname, or IP address of the outbound SIP Proxy. Valid only in [general] section and type=peer. (New in v1.2.x).

regexten =
regseconds = seconds : Number of seconds between SIP REGISTER. Valid only for realtime peer entries.
restrictcid : (yes/no) To have the callerid restricted -> sent as ANI; use this to hide the caller ID. This does not seem to work. This variable has been deprecated as of v1.2.x.
rtpkeepalive = seconds : Number of seconds, when a RTP Keepalive packet will be sent if no other RTP traffic on that connection. Default 0 (no RTP Keepalive). Valid only in [general] section and type=peer.
rtptimeout = seconds : Terminate call if x seconds of no RTP activity when we're not on hold. Valid only in [general] section and type=peer.
rtpholdtimeout = seconds : Terminate call if x seconds of no RTP activity when we're on hold (must be larger than rtptimeout). Valid only in [general] section and type=peer.
secret : If Asterisk is acting as a SIP Server, then this SIP client must login with this Password (A shared secret). If Asterisk is acting as a SIP client to a remote SIP server that requires SIP INVITE authentication, then this field is used to authenticate SIP INVITEs that Asterisk sends to the remote SIP server. Asterisk 1.6.2.x: Changed the secret parameter to remotesecret.
sendrpid = yes|no : If a Remote-Party-ID SIP header should be sent. Default no.
setvar = variable=value : Channel variable to be set for all calls from this peer/user.
subscribecontext = <context_name> : Set a specific context for SIP SUBSCRIBE requests
trunkname: Indicates this peer definition is for a SIP trunk. As a result, the $CALLERID(name) will start off blank and requires the dialplan to set the $CALLERID(name). (New in v1.6.x)
trustrpid = yes|no : If Remote-Party-ID SIP header should be trusted. Default no.
type = user|peer|friend : Relationship to client - outbound provider or full client?

usereqphone = yes|no : Indicates whether to add a ";user=phone" to the URI. Default no. Valid only in [general] and type=peer.
username = <username[@realm]> : If Asterisk is accepting SIP INVITE requests from a remote SIP client, this field specifies the user name for authentication. (Contrast with fromuser.) Also, for peers that register with Asterisk, this username is used in INVITEs until we have a registration.
vmexten = <string> : Dialplan extension to reach mailbox. Default asterisk. Valid only in [general] or type=peer.
Notes
Asterisk 1.6 and later support SIP over TCP. Before that it only supports SIP over UDP. Asterisk 1.8 comes with IPv6 support. For Grandstream phones: set dtmfmode=info Asterisk uses the incoming RTP Stream as a timing source for sending its outgoing Stream. If the incoming stream is interrupted due to silence suppression then musiconhold will be choppy. So in conclusion, you cannot use silence suppression. Make sure ALL SIP phones have disabled silence suppression. There is a solution for the silence suppression problem, see bug 5374 for details.
