Busy line after hang up calls
« on: January 12, 2018, 06:59:07 AM »
Hello,
Reading some documentation on google, I finaly found a way to make pstn calls from an ip subnet to an other using HT503 as FXO gateway and ht502 as FXS. Everything is going fine except that when a call is established and then hang up, the pstn line stays busy and wont disconnect until I reboot the ht503. I'm in Canada and I pretty sure about PSTN disconnect tone configuration for my country. Thanks.

Also look for:
   Enable Current Disconnect on the 503 FXO tab, set to YES.
   Current Disconnect Threshold (ms) set in 100ms jumps until reliable detection.  300, 400, 500 etc.

I assume you have already set:
   Enable PSTN Disconnect Tone Detection set to YES.
   PSTN Disconnect Tone is set correctly.
