Add flashlight in parallel of an IP Phone (7911)

For a chocalate factory the customer uses on the former PBX a flashlight is parallel on their phone.

When a phone rings, the flashlight is flashing.

On the Callmanager Express 4.0.3, we have connect the flashlight on a FXS port, but the problem is to add the FXS port in parallel of a IP-Phone.

I guess the easiest way is to use the ATA-interface, but the customer would like to use the Feature mode SCCP FXS port.

I have found that the recommend IOS for CME 4.0 is 12.4(4)XC, but for the SCCP feature 12.4.(6) or higher is recommend.

Can somebody advise if the SCCP feature on a Callmanager Express support to put an FXS port in parallel of a ephone-dn?

Thanks

Ronald

Re: Add flashlight in parallel of an IP Phone (7911)

The recommended IOS for CME 4.0 is actually 12.4(9)T unless you are using 7931 phones.

Note that per documentation, two routers are used, one is a voice gateway chosen from the platforms listed, and a separate controlling CM or CME.
