[cisco-voip] FXO disconnect problem.

[Ahmed Elnagar]

Hello ya hady;
 
Two ways to solve this problem:
 
1- Use H323 instead of MGCP on the gateway with the "connection plar opx " command and in most of the cases it solves the probelm.
2- If you want to use mgcp "or h323 didnot solve it" then you must know exactly the disconnect frequency that TelecomEgypt send when a call disconnects "as this is the root cause of the problem that the router doesnot understand this signal"
 
Unfortunaltly that TE doesnot has a standard for this tone "I asked them b4 and they told me they didnot care for this" then it depends on the CO. that you are connected to, anyway the values are so close and they are as follows:
 
frequency 450cadence 250 250
 
configure them in a voice class and apply the voice class as a custome supervisory tone to the voice ports
 
If you need more help I will be more than happy to assisst, I faced this problem alot here in Egypt with different CO.s and I think I can help u ISA.
 
Thanks
