Hello,
i´ve got a problem with my softphone over VPN. I´m not able to answer calls. The softphone rings twice and then gets busy. The answer incomming call button doesn´t work. has anyone seen this?
Thanks in advance
You need to ensure that the ports required for softphone to function correctly are not being blocked by firewalls on your PC or VPN box/Company side, also do you have QOS set anywhere?
this is definitely a firewall problem.
the call is ringing because H323 signaling is done on fixed TCP ports 1719 and 1720.
voice circulate on dynamically assigned UDP ports, so most probably the firewall is blocking these.
So u basically what you need to do is to config your firewall from both ends
He stated they are using a vpn, that would mean that all ports should be open through the tunnel. Make sure windows firewall is not interferring and maybe run the avayaFW.bat just to be safe.
