CME 7.1 call forward PRI to Analog Problem


Hi I have a CME 7.1 with a pri conection and 4 FXO port with 4 mobile line conected to the router.

If I call form a nation number (form PRI line) and I have a cfa to a mobile number (going to FXO ports), I don't hear any tone from the calling party, the mobile is ringing, I pick up the call but I cannot hear any sound in both side.

Anyway if someone transfer me to a mobile number, the call goes ok.

Any suggestion ?

Thank you a lot for the help.

Best regards.

Update IOS and try again.

Hi Paolo,

thank you for your help, do you think could be a IOS bug? The version is 15.0(1)M4.

I don't have much experience with analog lines, but sound really strange to me don't get any tone when the cfa is active on the ipphone. The other strange thing is the ipphone with cfa active ring when I make a call, and it keeps ring till I receive the call on the mobile, and believe me I put call-forward all command in the ephone-dn.

Thank you for your help. 

As mentioned above, update and revise configuration.
