VOIP and T-Mobile Home Internet Fixed

Today I have fixed the VOIP issue with T-mobile Home Internet and VOIP.  

Firstly T-mobile to prevent outside packet attacks to susceptible ports 5060 and 5061 updated their settings to not allow through Sip protocol through those ports. 

You cannot access the backend of the modem and outside modems that are highly modifiable like the Gli.net 5G modem. Don't work to assist you in the matter, because its a block by the server end of T-mobile not the routers themselves. 

I know this because I tried every means to configure the GL-X3000 Spitz modem to work with t-mobile over the last month and it would not go.

So, now the only solution since it's not a user side issue or router issue, is to bypass the T-mobile network settings blocking your 5060 and 5061 SIP ports. 

Here is how you can go around this. This... was such an easy fix I wanted to cry.

Step 1: Call your hosting VOIP network operator. 

Step 2: Have them go to network settings on your VOIP system background. 

Step 3: Turn you UDP port 5060 and 5061 to TCP

Step 4: Turn off your VOIP devices, servers, programs and applications. 

Step 5: Turn them back on and now you can make outbound calls and inbound calls without issue.

Works for Max UC and other VOIP services, Verified. 

You are welcome.
