Troubleshooting the outgoing ISDN-testcall command
If the
TestCall BCC
field appears on the Trunk Group screen, ensure that 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:
If the ISDN-PRI trunk is of type
cbc
make sure the
TestCall Service
field on the Trunk Group
screen 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 screen for the call to be allowed.
