FXO disconnect problem with PBX Ericsson BP 250

Answered Question
Jun 25th, 2008

Hello,

I have connected a PBX ericsson BP 250 to an FXO in my voice enabled router 2811.

The problem is:

When an analog phone attached to the PBX calls an IP phone registred with the CME, the IP phone ring normally. But when the analog phone goes on-hook, the IP phone continues to ring.

Please can you help me.

Thank you very much.

I have this problem too.

Hi, these should be CPTs for Tunisia:

Check if your PBX is actually using one of these.

Have tried OPX first ?

For the parameters, set cptone as per you country under voice port. That may be enough.

Then yes you need supervisory disconnect. If the default doesn't work, tell us which country are you in, record the tones with a PC and attach the file here.
