Hi,

>From RFC 3261:
To be compliant with this specification, applications sending SIP messages MUST 
include a SIP-Version of "SIP/2.0"
This message have "SIP/3.C" as a version, and that means it is not SIP.

Most likely it is some proprietary Motorola protocol.

Sergey.

Subject: [Sip-implementors] (Please help ) question regarding sip void and media 
connections
Importance: High


Hello,
 
  I probably should not ask you this, but was wondering if some could help me to 
figure out a small problem that I am having with Motorola sip implementation. I  am 
working on sip protocol , and found interesting thing that Motorola Winphoria server 
does not use SDP for transport protocol/ports negotiation , they stick all the fields 
that SDP provides directly into SIP header then all audio goes on port 2300  and RTCP 
2301. I also don't see any media and connection negotiation.
 
Have any of you ever seen this before ? I can not find this in RFC 3261 or in any 
other RFC's  
 
Example :
INVITE tel:3127190656 SIP/3.C^M
t: 
i: 731257426:[EMAIL PROTECTED]
CSeq: 1
v:166.181.26.77
f: <tel:3127196154>;tag=1083783859
2
I
x: sid=1010;
o=Winphoria 2300 0 IN IP4 166.181.26.77:60
 
 
Also do you know by any chance what this means:
SIP/3.C 200 OK 
 
By the standard you should have version as 2.0:


SIP/2.0 200 OK
Thanks a lot in advance !
-Aleks
