My FreePBX server is connected to the Planet VGW-400 (FXO). The FXO Box is connected with 2 PSTN line.
The problem is that when a user call in from outside through one of the PSTN line, it reach the IVR and when the user dial an extension, the extension will be ringing, the user then decided to hang up the call (the user inside havent pick up the call yet), the call still continue even after the user from outside hang up the call.
Thanks in adance
Looks like you have problem with answer supervison or disconnection tone, read this document ftp://ftp.planet.com.tw/VoIP/FAQ/FAQ-Case15%20VIP-880%20Answer%20Supervision.pdf or search on user manual Planet VGW-400 about answer supervison or disconnection tone.
The given guide is not for Planet VGW-400-FO.
I didn’t find answer supervison or disconnection tone on my Planet VGW-400-FO.
Thanks for your reply
