Troubleshooting Guide
SYMPTOM
Cannot dial
international numbers
when connected to
DMS500 switch
running DMS100
protocol.
DID call with number in
the name portion fails
to access Auto
Attendant directly.
The 3300 ICP is
inter-operating with a
Tenovis PBX via a
Q.Sig trunk. A station
on the Tenovis PBX is
unable to display the
CLID of an incoming
call.

Table 33: Digital Trunk Troubleshooting
PROBABLE CAUSE
System is connected to a DMS500
switch running DMS100 NI1
protocol and the service provider
has an NI2 table programmed in
the central office. The protocol may
set correctly in the central office;
however the NI2 table should not
be programmed.
Inbound ISDN calls which present
numbers in the name portion of the
call will not complete. The voice
mail which uses screen scrapes
are seeing the numbers in the
name portion of the caller as choice
or extension number, instead of a
trunk call, As a result, the DID
caller does not hear the auto
attendant greeting and may hear
other voice mail option or "please
enter your mailbox number
prompt".
The 3300 ICP is the transit PBX
and is running a software version
that is earlier than 3300 Release
7.0 UR2. Both Mitel and Tenovis
follow the Q.Sig specification but
they use different options. This is
an interoperability issue between
the two systems.
CORRECTIVE ACTION
Refer to Mitel Knowledge Base article
05-5107-00005.
In the voice mail port's class of service, set the
following:
• display ani/isdn calling number only YES
• display ani/dnis/isdn calling/called number
YES.
Upgrade to 3300 Release 7.0 UR2 or later. In
addition, the following programming is required:
For an embedded NSU with Release 3300 7.0
UR2 or later software:
1. Access the System Administration Tool on the
3300 ICP.
2. Select the ISDN Protocol form.
3. Enter "ctcomplete" in the comment field of the
ISDN Protocol form for the corresponding
Q.Sig link.
For a NSU with 3300 Release 7.0 UR2 or later
software
1. Access the IMAT tool.
2. Select the PRI link characteristics.
3. Enter "ctcomplete" in the comment field.
Ensure that you save the changes in the NSU.
