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.

Do you have caller-id enabled ?

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

You may need to upgreade to a minimum of 12.3XW to use "immediate" in "connection plar opx". Check:
