[Sofia-sip-devel] How do I do nua to respond 488 using SOA

[Paulo Pizarro]

Hi all,

On the "basic" inbound call model:

       APPL            NUA             SOA                    REMOTE
        |               |               |                       |
 0      |               |               |                       |
 1      |               |<------------------INVITE(sdp offer)---|
 2      |               |               |                       |
 3      |               |--set_remote-->|                       |
 4      |               |               |                       |
 5      |<---INVITE-----|               |                       |
 6      |               |               |                       |
 7      |               |               |                       |
 8      |- - -180- - - >|               |                       |
 9      |               |- - - - - - - - - - 180 Ringing - - - >|
10      |               |               |                       |
11      |               |               |                       |
12      |-----200------>|               |                       |
13      |               |--set_params-->|                       |
14      |               |               |                       |
15      |               |--gen_answer-->|                       |
16      |               |               |                       |
17      |<----active----|               |                       |
18      |               |----activate-->|                       |
19      |               |--------------------200 (sdp answer)-->|
20      |               |               |                       |
21      |               |               |                       |
22      |               |<------------------------ACK-----------|
23      |<-----ACK------|               |                       |
24      |               |               |                       |
        |               |               |                       |

In line 12, the application calls nua_respond with 200, if there is no
common codecs, soa generates an answer SDP with "m=audio 0 RTP/AVP 0 8".

How do I make nua to respond 488 using soa?

Thanks in advance,

Paulo Pizarro
