Hi All.

I am making TrFO IP-IP call flow for IMS MGW.

I have some question.

- Are there packages for TrFO for IMS MGW?
- How about sdp attributes?
- where can I find TrFO IP-IP call flow for IMS MGW?
- I tried to make Add message for TrFO IP-IP call as following.
What do you think about this message?

MEGACO/1 [172.21.0.100]:2944
Transaction = 1000 {
Context = $ {
Add = RTP2/$ {
Media {
LocalControl { Mode = SendReceive },
Local {
v=0
c=IN IP4 $
m=audio $ RTP/AVP 97
a=rtpmap:97 AMR/8000/1
Remote {
v=0
c=IN IP4 172.30.0.100
m=audio 40124 RTP/AVP 97
a=rtpmap:97 AMR/8000/1
} } },
Add = RTP4/$ {
Media {
LocalControl { Mode = SendReceive },
Local {
v=0
c=IN IP4 $
m=audio $ RTP/AVP 97
a=rtpmap:97 AMR/8000/1
Remote {
v=0
c=IN IP4 172.40.0.100
m=audio 43922 RTP/AVP 97
a=rtpmap:97 AMR/8000/1
} } } } }

- In above message, I expressed TerminationID as RTP2/$, RTP4/$.
Is it possible to express ephemeral Termination as above?

Thank you in advance for your help.
