We do not have a document on the configuring SIP trunking with this service provider. I would recommend using the document below and follow the instructions for configuring a service provider SIP trunk. Consult the service provider for any specific configuration items required for their service.
I went ahead and flagged the "Correct Answer" on this post to make it more visible and help other members of the community find solutions more easily. If you don't feel like the answer I marked was correct, feel free to come back to this post to unmark it and select another in its place with the applicable buttons. If you still need assistance, we would be more than happy to continue working with you on this - just let us know in a reply.
Sotel is not compatible with the 7100.
It requires that we proxy the media when forwarding calls.
Otherwise we need to have another device to terminate the carrier SIP truck and has have the SBC firmware in it.
