[asterisk-users] Unable to hear voice when called from PSTN phone line

[Supratik Goswami]

Hi,

My asterisk server is running behind a NAT/Firewall and I am using Skype for
Asterisk.
I am able to communicate using two SIP extension one connected from within
the LAN and
the other connected from outside my network.

The problem is when I am trying to communicate using a PSTN phone I am able
to establish a connection
but I am not able to hear anything.

Can someone help me to solve this issue.

Regards

Supratik
