SIP Routing in Yate

Revision as of 15:17, 7 November 2012

In this chapter is described how to route a SIP channel and a SIP line (gateway).

Route to a SIP channel

From a routing module (e.g regexroute.conf) you can call an sip channel like this:

extension=sip/sip:user@ip:port

Configure a SIP line

From accfile.conf you can configure a SIP line when Yate is registering itself to a remote server.
Sections with enabled=no are always ignored so you have to changed it to enabled=yes.

Parameter description for SIP:

• protocol: The protocol to register on
• username: Account username
• password: Account password
• interval: Registration interval (in seconds) to request from server
• description: Caller name to set on outgoing calls on this account if none specified when routing
• registrar: Registrar address. A port can be specified here (e.g. 1.2.3.4:7999)
• authname: Authentication name to use instead of username when authenticating
• domain: Authentication domain if any
• outbound: Optional outbound proxy server if different from registrar. A port can be specified here (e.g. 1.2.3.4:7999)
• ip_transport: Optional SIP transport to use (udp, tcp, tls).
• ip_transport_remoteip: IP address to connect to register the account.
• ip_transport_remoteport: IP port to connect to register the account.
• ip_transport_localip: UDP: This parameter is used in conjuction ip_transport_localport to identify the transport to use.
• TCP/TLS: Optional local ip to use when connecting ip_transport_localport: Local port.
• UDP only: This parameter is used to identify the transport to use
• localaddress: Local address to set in sent messages

- Set it to 'yes' to detect NAT and re-register with public ip when NAT is detected

- Set it to 'no' or ipaddress (e.g. 1.2.3.4 or 1.2.3.4:5060) to disable NAT detection

• keepalive: Optional interval for NAT keep alive.

Note: Default port is 5060 for udp/tcp and 5061 for tls

This is an example: Configure a SIP line called [test_sip].

accfile.conf

[test_sip]
enabled=yes
protocol=sip
username=me
description=Test SIP account
interval=600
authname=metoo
password=1234
domain=somewhere.org
registrar=10.0.0.1:5060
outbound=10.0.0.1:5061
localaddress=192.168.0.1:5062

Route a call to the SIP line configured above:

regexroute.conf

^100$=line/100;line=test_sip
