This might be in the wrong topic, so feel free to move.
I’m having a bit of trouble trying to get my Linksys SPA3102 to detect the PSTN disconnect tone that is played when the incoming caller hangs up. Everything else on the device is working perfectly. It is connected to a TalkTalk (BT) landline in the UK. I’ve been googling around for the past week or so and tried most of the things that I have found.
I’ve recorded the disconnect tone and measured this at 395Hz at -20, changed the string but no luck. I have been able to get hold of a patton box to also test with and if I set it to detect the busy tone, with the settings below, it works. I have also tried inputting the busy tone string into the linksys but also no luck.
I think I’m missing something obvious here, so any help is appreciated.
Patton busy tone config:
1: play 375ms 400Hz 0dm
2: pause 375ms
Disconnect tone recording:
If anyone can point me in the right direction with this then that would be great. I’m starting to think I have a faulty unit.
