Dos VitalPBX V2 support PRACK & 100rel?

Dear friends,
Anybody konw it? I want to know about PRACK & 100rel can be use in VitalPBX?

How to configure it?

PRACK 100rel.

Are you using PJSIP? I guess it is supported by PJSIP endpoints.

Yes,I have configured a pjsip trunk,and from the pcap i can see the prack message. But destination need vitalpbx send support 100rel. And i set a 100rel yes in ytunk advance settings. But it doesn’t work. So how to config 100rel?

100rel comes enabled by default on PJSIP endpoints.

That means, that you add it as a custom object in the PJSIP profile in the GUI.
