Hi
By setting: branch_expire to the same value as dialog_expire which is 12 hours, now my headers get correctly restored on UPDATE and BYE.
But in this UPDATE scenario:
CPE A => Registrar A (topos) => Core => Registrar B (topos) => CPE B
I now have the phenomena that the Contact Header is being removed from the UPDATE by topos on Registrar B.
Any clue what could cause the issue?
I see that Registrar A is adding a P-SR-XUID hader. Maybe I could filter that header out on the Core?
Mit freundlichen Grüssen
