We have some problems with the call disconnection on a FXO ports in CCME 7.1 environment. We have a 2N Analog-GSM gateway attached to a FXO port, and the CCME did not recognise the disconnect tone, so the call was never disconnect (you had to end the call manually). We solved this problem analyzing the discconnect tone an creating a custom cptone:
voice class custom-cptone 2n-gsm
cadence 330 330
This is the configuration of the voice-port:
supervisory disconnect dualtone mid-call
supervisory custom-cptone 2n-gsm
timeouts call-disconnect 1
timeouts wait-release 1
timing sup-disconnect 50
connection plar 3001
Although it works, now we have detected a minor problem: the call takes about 2-3 seconds to be disconnected, so when someone is recording a message in the voicemail it records the disconnect tone during 2-3 seconds at the end of the message. I have changed the timeouts values with no results. Does anybody know how to fix it?
Thanks in advance.
