[asterisk-users] One way voice with Asterisk

[Dan Journo]

> When I dial into Asterisk ( I have a SIP trunk - which I need to make 
> sure is not faulty), I only get one-way voice communication.
> The calling party, from the SIP trunk hears nothing - the extension 
> rings on the Asterisk server (you can see it in the CLI and hear it at 
> the computer), and the softphone rings

Try canredirect=no on both your sip peer and your sip provider.
