there are few things,

1. capability PCMU/PCMA needs to be inverted
2. when you place outgoing calls SIP_user => FS => H323_endpoint FS corediumps: what is the data format for bridge? Is that correct => data="h323/1001@10.1.1.1" ?
3. when you place incoming calls H323_endpoint => FS => SIPUser, the call goes through but there is no audio. After H.225 connect and TCS/MSD, FS stops sending RTP back to te originator.
4. when you place incoming calls H323_endpoint => FS => SIPUser and you hangup from SIPUser side, the call is not released on H323 side... switch_core_state_machine complains about a wrong thread.


i will send you logs for:

1. slow start
2. slow start early h245
3. fast start tunneling true
4. faststart tunneling false
5. faststart with early h245 tunneling true
6. faststart with early h245 tunneling false


do you need a tcpdump for every scenario as well ?
