Hi,

When Openser receives a malformed INVITE with SIP version set to 10.0 in the Request Line, it just processes it as a normal INVITE.

The Request Line of the INVITE message received looks like this:

INVITE sip:ua1@domain.com SIP/10.0

According to RFC 3261, the Requests should contain SIP/2.0. Hence Openser should drop this request with an appropriate 4xx reponse.

But this behavior is not seen.

Do I have to modify my openser.cfg for validating the above INVITE?

Any help would be appreciated.

Thanks,

Aadil
