I do hope not, the network team should be sick of me hammering home not to set up NAT on these routes :D

9 out of 10 it will be a NAT problem.

Hi,

I've nearly completed the process of upgrading our ancient v1.7 deployment to v3.6. The new deployment is installed on Ubuntu 24.04 from the OpenSIPS repos. These servers are our inbound hand-off from our upstream supplier, they take a call, inspect the called number element against the database, and then pass it on to the target system with the internal reference or decline the call.
