Mitel 3000 Australia Installation and Maintenance Manual
Mitel 3000 provides a message-waiting signal to standard telephones
using the CallerID protocol. The CID signal is preceded by a reversal to
put the phone into "listening" mode so that it correctly detects the signal.
On some older phones with electromechanical ringers the bell will
"tinkle" when a reversal is sent. So if an extension is programmed with a
voice mail box, or is in a group that has a group box, it may tinkle when
the signal to turn the 'message waiting' indication on or off is sent to it.
The message is sent: -
When a new message is left in a box.
When the indication is being turned off.
It is also sent some seconds after the handset is replaced on every call.
This is to ensure that the message indicator on CID phones are in sync
with the voice mailbox. This may cause the bell to tinkle about 5
seconds after the user goes on-hook.
If Caller ID is not provided on the lines and the system is programmed
to expect Caller ID, there will be a delay between calls being presented
to the system and the extensions ringing. This is caused by the system
trying to detect the Caller ID signal after the first ring burst. It delays a
period of several seconds trying to detect the Caller ID signal before it
rings the extensions. This delay can be eliminated by reprogramming
the lines not to detect caller ID.
If Caller ID is presented on the line, there is a delay as the system
detects the Caller ID information after the first ringing burst and
transmits it to the extensions. The extensions are rung when the Caller
ID information has been decoded and the information can be presented
to the extensions. This can cause a delay of some seconds before the
extensions are rung.
This is because the line or lines are incorrectly programmed as "Loop
Calling" lines. Go into programming lines and turn the loop calling off for
all lines.
Loop calling should only be used for a ring down circuit / tie line.
If a call is made by dialing 0 and continuing to dial the phone number
without waiting for the PSTN line dial tone, there will be a delay in
switching through the speech path after the call is dialed. This is
because the system stores the digits and then resends them once the
Network provider dial tone is detected. However, the system does not
know when the last digit is dialed so it switches the speech path through
if it has not detected a dialed digit for about 4 seconds.
If this is causing a problem, users should wait after dialing 0 and then
continue dialing the number when they hear the Network provider dial
tone.
This delay will always be present if they use redial on standard phones.
