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

Hi,
My carrier doesn't like the invites that come from two specific
customers I have, who both use something called VoipSwitch. It returns
from the carrier as a Bad Request.
Below is the dialog - I'm not sharp enough to see what's wrong - anyone?
Thanks!
