488 Not Acceptable response for INVITE with no media SDP - should be 200 OK

[GoogleCodeExporter]

Hi,

When Boghe receives initial INVITE with no media SDP content it generates 488 
Not Acceptable response with the Reason header:
Reason: SIP; cause=488; text="Bad content"

No media SDP content from the initial INVITE:
v=0
o=- 2890844526 1 IN IP4 ictbackyard.com
s=
c=IN IP4 ictbackyard.com
t=0 0

My understanding is UE should respond with the 200 answer with no media SDP.

I am using version 2.0.112.744 on Windows 7 64bit.

I kindly ask for your support
Regards
Tomasz

"My understanding is UE should respond with the 200 answer with no media SDP" 
-> could you point any RFC?

Sure.
http://tools.ietf.org/html/rfc3264#page-5 - "The offer will contain zero or 
more media streams (each media stream is described by an "m=" line and its 
associated attributes)."
