Dial-up over VOIP

Good day

I’d like to clarify why I can’t access my email and browse to the net using VOIP dial-up configuration.

Listed below are the problems I’ve encountered during the testing:

From remote site I tried to dial-out to the internet using VOIP connection, I did able to access my account and successfully connected to the ISP server, but when I browse to the internet, it doesn’t work, I can’t access to the net as well as my email

Network setup

a. My VOIP setup is that I have 2651 router with 4 fxo port at the main office, connected to telco line,

b. remote site has 2651 router with FXS card connected to PBX unit.

Hope you can help me.

Re: Dial-up over VOIP

Hi Arnold -

What is the codec you are using? g.711 should work fine.
