I'm actually being told that it does not matter if it's digital or analog as long as it can do the " E606 (Contact ID) event code" for the telguard wireless communicator.

Who would program this phone? Would the thyssenkrupp tech know how to setup the phone or would I have to contact Rath or EMS to do this?

Basically, Telguard will only work with alarm companies and the alarm companies feel extremely uncomfortable messing with the elevator phone. This is why I'm hitting so many roadblocks.

Thanks.
