One way audio on Re-INVITE #123

Call Flow

Inbound Call, with outdial to PBX

SBC -> Jambonz -> PBX

When a PBX user holds and un-holds the call, we receive a re-INVITE from the pbx B-leg with sendrecv in SDP. The b-leg sends and receives rtp for duration of the call including after the re-invite.

However the A-Leg only receives rtp from the B-leg up to the point of the re-invite and then the PBX rtp ends.

I have sent a pcap to support@jambonz.org

I think we may have a fix for this in the latest code. Is this a scenario that is easy to recreate in a dev environment?
