Hi, thanks for your response I have two users (1000 and 1001), and the FS conference room (3000) User 1000 call the conference room and he wants the conference room to add user 1001 into the conference. Like that they can speak each other into the same conference. How do I have to do this? Is it like this: 1- 1000 call 3000 2- 1000 call 1001 3- then 1000 send a refer to 3000 to add 1001 into the conference? Thanks for your help 2015-08-18 3:35 GMT+02:00 Ítalo Rossi <italorossib@gmail.com>:
You're trying to transfer 1 legged call:
2015-08-07 13:21:45.615060 [ERR] sofia.c:8297 Cannot Blind Transfer 1 Legged calls
You need dial to the user first and then transfer it to the conference extension, after this you can dial the conference extension.

Hi,
I have a problem with the SIP message REFER. I initiate a conference by entering into a conference room, and then I want Freeswitch to add a new participant. According to the RFC 4579, I sent a REFER message to Freeswitch to add the new participant and I get back a NOTIFY with sipfrag 403 forbidden
I'm working with virtual IP adresses and I'm working only in local
Below is the REFER message I send
