VoIP and SIP Module - Phones not registering

Ok. So I have a unique situation. We have implemented VoIP in our network and I have everything up and running and working great. Our XG currently has the SIP Module enabled and we are working. We have another company working within our network that has their own VoIP provider and their phones will not provision. They are standard Yealink T42S devices and they use ATT with ringcentral. I am trying to look at the logs, but from what I've read with the SIP Module enabled, I cannot see log information for that traffic specifically port 5060. I can see the device request time on port 123, and the time sets, but when it tries the request for registration, it never get a response. I have created and exception for ringcentral to bypass https checks and policy checks. Are there any logs that can be viewed via GUI or Device Console to see the SIP information? Any guidance or assistance is appreciated.
