my client have tde600
remote extentions sip work by vpn
the extention is working and the mic is working but the extention cant hear the 3rd party talk too.

i opened ports for the dsp and 5060 to the pbx.

anyone know?
 
give priority to voice traffic in firewall
check codec settings in phone and pbx E.g g711 u or Gg711 a
tcp/udp flood disable
if there is one way audio use symmetric rtp.
check network latency must be less than 150ms
nat setting in firewall must be disabled
 
If its on a vpn you don’t need the ports open on the firewall. Does it work on the local site?
 
Sounds like the VPN is not routing properly

Is it a site to site VPN or an ssl one on the phone/pc
 
Is the traffic from the Phone network fully permitted to the network where the PBX is?
