Hi All,
I have the following doubt in SDP.
UA1 ========================> UA2
Invite(SDP) ------------------>
>From UA1:
SDP has both audio & video capabilities.
At UA2:
UA2 doesn't have audio capability & so it doesn't
know any codec. But according to RFC 3264, it MUST
reply something for audio. We have two choices -
1) Reply with port = 0
--> But we don't know the codecs?
2) Reply with inactive
--> But we don't know the codecs?
Is it feasible to use either of the approach?
Please correct me if I am wrong?
is it valid to construct m= lines in SDP without
any codec?
With regards
Somesh S. Shanbhag
