We have installed 3CX PBX on our server and want to use Vigor 3300V with FXO to connect to PSTN.
Using Internet Hotline feature of FXO port settings in Vigor 3300V we were able to forward all incoming calls from PSTN through FXO port to virtual extension of 3CX and get the call in 3CX successfully.
Howerver, still we are unable to configure Vigor 3300 & 3CX to pass call out from 3CX through Vigor 3300V FXO ports to PSTN..
Need some assistance on settings required..
