Re: Cellspot
Same issue here. T-Mo is telling me that Xfinity is blocking ports 123, 500, and 4500. I know for a fact that this is not the case. I have tested the UDP ports, and they are all open with Comcast. T-Mo seems to have a default set of answers when it comes to troubleshooting this device. 1. Your Internet provider is blocking the ports 2.This is a known issue and it is taking longer than usual to register on our network 3. Defective device, we'll send another. I have had so many replacement devices that I have lost count. The last time this happened, the device just started working one day. It sure would be nice to have a T-Mo tech who knows how to troubleshoot these things because not being able to make a call while at home is a major PITA. WiFi calling blows.2Visto0likes0Comentarios
