[VAMBARA, SAMPATH (SAMPATH)** CTR **]

Hello,

Some of my test cases are failing while testing our SIP application on a SIP stack.
Can some one please tell me if any of the mandatory headers are missing in a SIP request, how the message should be handle by the SIP stack.

For example.
1) If call ID is malformed and it is having an invalid character like call-Id:\t\b\c at xxx.com
As per RFC, '\' is an invalid character for called.

2) If Callid is not at all present in a SIP request or an incomplete message is received so that some of the mandatory headers are missing in the request.

Thanks & Regards,
Sampath
