Unanswered Question
Jul 2nd, 2008

Hi,

I have Cisco 2821 router IOS version 12.4(11)XW1, with FXO ports.

incoming calls to FXO from the PSTN side rings twice before it rings on the IP phone.

I have the same issue using call manager and call manager express.

could you please advice.

I have this problem too.

Hi Bevilacqu,

Yes, caller-ID is enabled on the router on all FXO ports
