Just to be clear, is it fair to assume this is an FXS?
Assuming so, my understanding is that you create a Phone Trunk of type SIP and set up the protocols etc.
Then create a Phone Base settings for a Generic SIP phone.
Next, create your Phones based on the Base settings.
Finally, configure the FXS to register (as the created Phones) with the Edge.
