FXO to CDMA Fixed line disconnect problem.

[kelly.amisi]

Hello All,

I have done the requisite searches but none address my specific query.

My query i have a Cisco 2801 router with FXO ports connected to a Huawei FT2250 Fixed line terminal. I am able to make a CSIM START XXXXXXX out of the port but the call disconnects after a couple of seconds. Secondly i have configured connection plar XXX to automatically dial a number, when i make an inbound call into the router the call is disconnected after a couple of seconds.

I have tried various configurations settings but the problem persists.I await your enlightened responses.

Hi Paolo,

I've tried that and it doesnt work either, disconnects after a couple of seconds.

Check that device interface is FXS, to be connected to FXO.

[kelly.amisi]

This has also been confirmed.

Then you can take "debug vpm signal". Possibly you will see "power denial" meaning device is not supplying loop current in off-hook state.

You can test the device with a regular telephone.

Other than that, nothing can be done on the Cisco.

I already did that before and it was working fine. However the thing is, it was working before we moved it to a new router of similiar specs, so how do you explain this anomaly.

Secondly if nothing can be done on the Cisco, what can be done on the Huawei device.

Sorry, I don't know.
