[OpenSIPS-Users] ACK not forwarding

[Schneur Rosenberg]

My ACK coming from this device does not get forwarded to its designated
destination, I see that the RURI is to my OpenSIPS server even though the
contact has been rewritten in the OK, is that the reason the OpenSIPS
thinks its for himself? if yes how can I workaround the issue, perhaps with
dialog module etc?

Below please find the OK and the ACK, it has a Record route and proper
contact.
