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 ?
