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

Use section [methods] from ysipchan.conf to allow/restrict the processing of specific SIP methods. For enabled methods yate will generate internal messages with name sip.<methodname> that can be handled from other modules.

Examples

Enable MESSAGE Method

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}

Enable SUBSCRIBE Method

ysipchan.conf

[methods]
subscribe=yes

You then configure the allowed events for subscribing in sipfeatures.conf and define the logic for SUBSCRIBE/NOTIFY in subscription.conf.

Then you have to set what you need in sipfeatures.conf and in subscription.conf.
