but i have issue..on FXO port...

when calls coming inside...it shows unknown call...

how can see the caller details on phone?

[islam.kamal]

Hello

Thanks so much for your rating , and i am so happy that your issue solved. Look i am sorry for the delay because i have to check the config before debugs. Anyway can you do a new debug " debug ccapi inout" for incoming call .Keep your mid there all two possible cases for the problem

1- ITSP not send called id and this will check by debug after you will send.

2-Problem for MGCP , MGCP has a big problem to display caller id and most preferred solution is H323 with FXO.

HI

Timeouts wait-release is the amount of time that the FXO takes before the system starts the process for releasing voice  ports after a failed call.
