SIP Methods

This page describes the Sip methods that are handled by default in Yate and how to enable the ones that are not generically handled.

SIP Methods in Yate

Some standard SIP methods can be handled generically in Yate like INVITE, CANCEL, ACK, BYE, REFER, OPTIONS and REGISTER.

For example SIP method INFO in a dialog is handled internally by Yate but dialogless is handled generically (by using parameter lazy100 in ysipchan.conf).

Additional methods

In ysipchan.conf is section called [methods] that allows Yate to process SIP methods by handling messages with name sip.<methodname> (written in lower case).

Examples

1) Enable MESSAGE SIP

ysipchan.conf

[methods]
message=yes

In regexroute.conf

[extra]
sip.message=120

[sip.message]
.*=echo Got SIP MESSAGE type '${xsip_type}' ${xsip_body_encoding} from '${username}': ${xsip_body}

2) Enable SUBSCRIBE

ysipchan.conf

[methods]
subscribe=yes
