[Users] interrupts after 30 secconds

Looks like your GW is not doing a good job in record-routing OR your
openser is not doing it right. 

I only suppose than because:
- you have two different IP's for the openser\
- PRACK and ACK seem to be stuck in openser, and they do not reach your
UA in the internal network

Indeed, the network dump would be of much help.

Regards,
Cristian
