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

[Anders]

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!
