AID for analogue phones

Is it possible to use an caller ID equipment for MD analogue phones? by fcpli
Posted: 10 Mar 03 (Edited 21 Feb 05)

Yes, this is possible, but needs some modification:
1) For versions BC7,8,9,10 there is a patch, BC11 needs a license + a patch, in BC12 a license is needed

2) For ELU11/ELU21 boards some strapping and cutting is needed (no actve sustaining, so no source code available for
the HW any more). For ELU29 a PROM change is needed. NOTE!
ELU29/1 is NOT supported!

The functionality is controlled by ICAT parameter
just in order not to load the system in case some phone does
not have this function.

This works with internal and external lines (if they are sending the AID). The function slows down the incoming call sequence for about 1-4s, depending of how many digits we are receiving (max is 10 in this patch).
The telephone has to support DTMF.

Anybody really interested can put his Email on the forum in
order to get more information.

The functionality is not free of charge....
