i do more or less the same thing (tried all combinations of SOATAG_ ):
nua_invite(tech_pvt->nh,
SOATAG_USER_SDP_STR( buf_final ),
SOATAG_RTP_SORT(SOA_RTP_SORT_LOCAL),
RTP_SELECT(SOA_RTP_SELECT_COMMON),
TAG_END()
);
This is the SDP passed to nua_invite:
v=0
o=NFax 1638412668 1638412668 IN IP4 10.10.10.240
s=NFax
c=IN IP4 10.10.10.240
t=0 0
m=image 16384 udptl t38
a=T38FaxVersion:0
a=T38MaxBitRate:9600
a=T38FaxFillBitRemoval:0
a=T38FaxTranscodingMMR:0
a=T38FaxTranscodingJBIG:0
a=T38FaxRateManagement:transferredTCF
a=T38FaxMaxDatagram:400
This is what actually is sent out:
soa::local_sdp_str: "v=0
o=NFax 6547498866901436140 54553743616330857 IN IP4 10.10.10.240
s=NFax
c=IN IP4 10.10.10.240
t=0 0
a=sendrecv
m=audio 0 RTP/AVP 9
m=image 16384 UDPTL t38
a=T38FaxVersion:0
a=T38MaxBitRate:9600
a=T38FaxFillBitRemoval:0
a=T38FaxTranscodingMMR:0
a=T38FaxTranscodingJBIG:0
a=T38FaxRateManagement:transferredTCF
a=T38FaxMaxDatagram:400
"
Please note:
m=audio 0 RTP/AVP 9
which shouldn't be there and there is NO way at the moment to set it
correctly.
I believe we need a way to:
1) use the given RTP without any modification
2) alternatively a SOATAG_RTP_SELECT( SOA_RTP_SELECT_NONE ), that does
not inserts RTP data
Any other solution ??
