Hi all,

I m using a Cisco 1861 with FXO card connected to the PSTN.

Ø      When I made call, I don’t have a problem ( only some seconds for establishing a call )

Ø      For the received call , I did some tests from my GSM:

When I make a call to number (FXO) the ipphone ring, but if I stopped the call from my GSM, the ipphone still ringing ( 3 ring and stop ).

Please could someone help me to resolve this problem?

See in the attachment the configuration of the router.

Thanks advance

Hicham
