TMO-G4AR SIP Issues

Unable to make calls with VoIP phone. The phone will register/show online but SIP invites are not reaching our server to negotiate/start a call. So, registration traffic will hit our servers and the phone will register, but phone cannot make calls. Unable to get a packet capture from the T-Mobile device to troubleshoot if it's making it to the WAN side.
