I'm trying to configure an SPA3102 with as asterisk box.
I'm having an issue with the disconnect tone detection.
Right now I can have two configurations, one:
* If I receive a call on the PSTN and the caller disconnects before I answer the SPA3102 doesn't detect the disconnection and phones continue ringing. This configuration has a PSTN Ring Timeout very high (600).
* If I receive a call the phone rings for 5 seconds, stops, rings agains a couple seconds, stops, rings again, and continues like this until the caller disconnects. This configuration has a PSTN Ring Timeout with a default value (5).
I tried changing the Disconnect Tone with a lot of values I got from many places (including the values from www.3amsystems.com). I also tried with different FXO Port Impedance values.
I can't understand either why SAP3102 with an high PSTN Ring Timeout doesn't disconnect the call, and why it does a loop with ringing on the phone with the PSTN Ring Timeout set to low.
Anyone got any issues like this?
