SIP Alg on Tmobile home Internet

My digital phone would not call out or receive calls but I had a dial tone. 

I called my phone service provider and they said that I needed to disable my Sip and ALG. They said I would have to call my network provider to get them to do this. T-Mobile said that the network box that the KVD21 box do not have access to perform those functions. Their box is a simple set up with no configuration capabilities.

However I solved the problem by resetting my digital phone module and unplugging all cables and power connections from the router and phone module and then reconnecting them.

I can now receive and dial out.
