[Freeswitch-users] RFC 4579 and FreeSWITCH

[Rick Block]

A while ago there was a question about using REFER (RFC 4579 section 5.5) to add a new participant to a conference, see

http://lists.freeswitch.org/pipermail/freeswitch-users/2012-December/090370.html

Can someone who is successfully using this post a howto including the relevant config, and exact REFER that works?

We're getting a 202 Accepted in response to an out of dialog REFER, but no INVITE is being sent from FreeSWITCH.

Our config and REFER are as below.

Thanks,
Rick Block
