[Freeswitch-users] RFC 4579 and FreeSWITCH

[Francis Joanis]

Hi guys,

I started playing with FreeSWITCH to make conferences and I was curious
about the support for RFC 4579 (Call Control - Conferencing for User
Agents).

I was able to have FreeSWITCH return a ;isfocus parameter in the Contact
(from the 200 OK) and I tried to add a new participant to the conference
using a REFER (see RFC 4579 section 5.5), which generated the following log:

[ERR] sofia.c:7095 Cannot Blind Transfer 1 Legged calls

I think RFC 4579 is mentioned on the FS wiki as a "supported" RFC but is
this call flow currently supported?

Cheers and thanks for the awesome work in FS,
Francis
