Voice Lost after Call is Transferred through SIP Trunk

Symptom

When the inbound call from SIP, you answer it. And later do blind transfer for it through SIP trunk (or call forwarding setting on extension). After the 3rd party answer the call, both parties could hear nothing.

Solution

Go to the SIP Advanced setting page. Check the Allow RTP Re-Invite as No.
