Question Cannot hear audio from in\out calls
I have asterisk as pbx - it works in LAN perfectly...I can recieve and make calls...Asterisk also has a valid IP adress and no firewall!..so When i try to call phone in my LAN being far away from it...I can make and recieve calls but cant hear anything! Another thing...I have spa3102 connected to asterisk and spa provides pstn line ..So I can make PSTN calls and hear everything....
Can somebody tell me what is wrong??

This is typically a port being blocked at the firewall. It would also explain why LAN calls and Gateway calls work, but IP to IP calls to not... RTP is being blocked at a FW.
