Algerian supervisory disconnect

Hello I am having problems disconnecting external calls entering through a fxo port,

Has anybody some idea of what are the right parameters to configure a fxo port to support Algerian lines?

Are you sure that Algery supports supervisory disconnect ? Most countries do not.

Re: Algerian supervisory disconnect

Hi thanks for your replies, I am not sure if the telco supplies disconnect supervision; I am making test because I have a problem with the externals calls coming from the pstn trough the fxo ports: if the external phone?s user (caller) terminate the call before the ip phone user (called) hang up the call, the ip phone continues ringing and the fxo port continues off hook; the call is not correctly ended.

Have you got any ideas of the cause of the problem?

Indeed the problem is caused by lack of supervisory disconnection. If the telco sends a tone on caller hang-up, you can try supervisory tone disconnection as indicated in the above document.
