Problem with FXO ports

I connected some PSTN lines on FXO port which are on a EVM-HD-8FXS/DID module on a cisco router 3825. But when a call comes from outside it does not ring on the phone of the operator. The outgoing call are well routed through the FXO ports.

This is the command I put on each FXO port:

voice port 2/0/8

connection plar opx 4094

When I connect an analog phone on the PSTN line, it rings. The phone of the operator works very well.

What could be the problem ?

Can someone help ?

Regards,

Can you provide more of your config? I'm assuming you're running CME?

Re: Problem with FXO ports

Did you write any dial-peer for these calls? For examle;

dial-peer voice 100 voip

destination-pattern 4094

session target ipv4:"CM ip"

Hi,
