[Kamailio-Users] Error in header - where and how?

[Anders]

Hi Daniel,

Thanks...I think that I maybe understand... - let's see: What you're
saying is that the problem is the missing Max-Forwards in the initial
INVITE that I receive, right? If this is the case, should I solve this
by rewriting the INVITE and add a Max-Forwards, and if so, how would I
go about this?

Thanks a lot!
