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

[Daniel-Constantin Mierla]

Hello,

maybe it does not like the two Max-Forwards headers in forwarded invite.

Received invite does not have one, so you probably do two times max 
forward processing in you config, one time with 5 and one time with 10.

Cheers,
Daniel
