Hi!
We have faced an issue with the FXS port on our 2811 gateway with IOS ver Version 12.4(24)T2.
There is an analog phone connected to the port with the default settings stated below.

There is a SIP trunk towards this gateway configured on CUCM and the appropriate Route Pattern used for the phone extension.
When we call to that extension we can hear the dialing and waiting for the answer, but the phone on the test site is not ringing.
At the same time I can see that it is ringing according to the output:

What have been done?
I tried shut no shut, tried the second Voice Port - the same issue.
Tried another Phone - the same.
Tried to test with the verified cable - the same.
Could it be the faulty VIC2-2FXS card?
I would greatly appreciate it if you kindly provide some suggestions.
Regards, Denis.
