Troubleshooting the Outgoing
ISDN-Testcall Command
If the TestCall BCC field appears on the Trunk Group Administration form,
make sure the TestCall BCC field indicates the correct BCC for the service
provisioned on the ISDN-PRI trunk. The TestCall BCC values are defined as
follows:
0
1
2
3
4
If the ISDN-PRI trunk is of type cbc make sure the TestCall Service field on
the Trunk Group Administration form indicates the correct service so that a
network facility message can be sent across the ISDN-PRI network.
If the outgoing ISDN-PRI test call keeps aborting, make sure that the far-end
device can handle DCP Mode 0 or DCP Mode 1.
NOTE:
Before attempting to make an ISDN-PRI test call to the public network (that
is, the network is the far end), make sure that test call service is provisioned
by the network. The user must subscribe to Test Type 108 service and have
the correct far-end test call number administered on the Trunk Group form
for the call to be allowed.
