Ok here are some recent changes and updates from my phone tech.
1-Timing issues. Station Transfer recall was extended from 20 seconds to 45 seconds. This is a Hub/Node specific programming feature.
2-DTMF tone extended to 80 msecs.
3-Voice Mail DTMF tone extended to 80 msecs.
4-In station programming, intercom forward was set to "None."
5-In station programming, auto attendant transfer on busy, set to "No."
6-In system programming, auto attendant immediate transfer, set to "Yes."
7-In Voice Mail programming, transfer was set to "Blind.". This was
originally set to "Wait for Answer."
Calls from my cell phone to the system were also successful for the most part, but
there is still the intermittent dropped call. The diagnostic LED's on the PRI card,
showed the call never hit the PBX. This means there might still be an issue with
calls coming into the AT&T CO, although the LEC said there testing showed nothing
wrong.
During all of this work, one-on-one conversations with every site revealed no problem with intercom calls from one campus to the other. In my technical support
window with Vertical, the technician ruled out any problems on the network, since
site-to-site intercom calls were never lost. His conclusion was that dropped calls
were being caused by the Carrier or the Voice Mail system.
In retrospect, 45 seconds for Station Transfer Recall seems a little long. This might need to be shortened, so callers don't have to wait longer than they should.
Does any of that info help?
