Hi
Of course it's mandatory. The question is how UAC should react receiving
malformed SDP.
I was executing so far conformance test with Cisco Call Manager and Alcatel
OXE. Both responded with 200OK containing SDP filled with missing item.
When I ran the traffic through the SIP platform I got:
400 respons in case of SDP without "v=",
488 for "o=" and "c=",
200OK "s=" and "t="

Hi
Parameters such as :- 'v', 's','o', 't' & 'm' are mandatory parameters in
SDP RFC 4566 section 5.
So it respond with 400 BAD request.
Please correct me if i am wrong.
Thanks

Hi all
I’m working on technical SIP requirements for end-points devices and I can’t
find an answer for one question.
How UAS should behave receiving INVITE that contains SDP without one of
following items: v, o, s ,t.
For example having received IVITE without origin:
v=0
s=TT
c=IN IP4 10.15.21.1
t=0 0
Should it respond with 200OK with origin?
v=0
o=CiscoSystemsCCM-SIP 2000 1 IN IP4 10.15.21.1
s=SIP Call
c=IN IP4 10.15.21.1
t=0 0
or should it respond with 488Not acceptable Here? Are there any requirements
for that?
Thanks in advance,
Bartek
