Good Afternoon!
So i was hoping you folks could help with an issue that is driving me crazy.
I work for a small IT deployment department in a mid-sized telecommunications company and we have recently accepted a contract with an Adventure Resort business to provide outdoor WIFI, individual cabin WIFI and phones for 26+ cabin locations.
I’ve set up a couple of PBX deployments using FreePBX but have always used SIP lines with individual authentication. In this case, for setup and testing purposes prior to deployment, we are using a SIP trunk that is provided by our parent company. Our CO has tagged 2 DIDs for testing purposes on the trunk which is built on a static address also provided by our parent company. The CO has confirmed that the trunk is sending the DIDs across as 7 digits.
Anyways, I followed a few walkthrus for setting up the trunk and the inbound routes. So currently I have a freePBX server and 2 Grandstream 2130s for the test enviroment. The internet is provided through an Arris device with the PBXserver set in the DMZ. This is a very temporary test setup so I have no issue posting route / IP information.
SIP trunk IP: 69.176.9.16
SIP server address: 12.21.194.239
FreePBX server IP: 172.18.30.10
DIDs: 4798991, 4798992
The issue I’m having is that when I use the inbound route, it only works if there is no DID definition. Once I define a DID for either 4798991 or 4798992, I get Line is not in service. I did research and figured out how to perform a packet capture and I’ve saved it as a *.txt file. I’ll post the headers here I guess with the first instance having DID set and the second as allowing ANY:

I hope this is enough information to maybe get an idea of what’s causing the issue but if not, please advise on what would help out. Our CO has checked the trunk side and sees no configuration issues.
Thanks!
