Enable-3pcc is to make it where FreeSWITCH will accept an invite w/out an SDP.

To my knowledge it is not possible to use the originate command to send an invite without an SDP.

Subject: [Freeswitch-users] How to originate a SIP call without SDP

Is it possible to originate a SIP call from Freeswitch without SDP in the INVITE? (SDP offer/answer will happen in the 200 / ACK)

I have tried to play with the enable-3pcc variable without luck. Any help is very welcomed.

Thx a lot,
