I got Call ring but no Voice ,

HI all
i got 2 registered softphones
call ring is ok but i hear no voice and i hear a beep vocie every couple seconds
any suggestions ?

The only suggestion reasonably possible with that level of information is that you need to provide us information on your network topology (particularly location of NAT and firewalls), the Asterisk full log for the call and a SIP protocol trace taken from whichever channel driver you are using.

Missing audio is usually the result of NAT or firewall misconfiguration.
