DISA Calls do NOT disconnect 2

[bmadtiger]

Hi folks,

I'm in Manila, Philippines with 4 (analog) trunk lines from PLDT. As far as I know we have no Calling Party Control (CPC) signalling to notify our PBX that the caller has hung up. Our PBX is a Panasonic KX-TDE100.

The lack of CPC has only caused a problem now I am testing the DISA/Auto Attendant feature. Without DISA, if the caller hangs, up, the internal extension stops ringing (within a few seconds). BUT if I enable DISA on a CO line and then call that line - the OGM plays and I can select an option, then hang up, but the internal extension keeps ringing (and following the ICD rules of redirecting to other extensions etc). Of course, when you answer the call, there is nothing on the other end (or maybe a busy tone).

If our provide cannot send the CPC signal - how else do we detect that the caller has hung up when using DISA?

Why is this different when using DISA? It works fine when not using DISA...

Thanks

Hi

if "the calls to disconnect after time but if people are answering the calls they will still get the dead line if someone hangs up"

What will be the best idea for getting other inter-site's CO?
