9 Troubleshooting
Reasons
The configuration of the RemoteCode parameter in the
pabx.cfg is missing or does not match the corresponding
dial-in number mapping in the route.cfg.
There is no route configured for the ISDN dial-in number
in the route.cfg.
The ISDN dial-in number was configured in the route.cfg
using the wrong number format (i.e. the trunk number
or extension are missing).
The ISDN dial-in number that has been configured in the
route.cfg is used for other data routings as well.
Symptoms
The system cannot be accessed from remote using
ISDN.
Solution
In the pabx.cfg, check the configuration of the
RemoteCode
configuration is RemoteCode=BBB, BBB is defined as
the dial-in prefix for ISDN remote access.
Check the route.cfg file for a matching mapping of an
ISDN dial-in number. The mapping that matches the
above RemoteCode parameter is MapAll<num>=BBB
DATA whereby <num> is the ISDN dial-in number.
Ensure that you use the correct ISDN dial-in number
format (i.e. trunk number plus extension or extension
only) by changing the above mapping to the following
catch-all parameter: MapAll?=BBB DATA and by tracing
the routing attempt. The trace file tells you the correct
number format. Adjust the mapping accordingly.
Make sure that your ISDN dial-in number is not used for
any other data routings by taking the same steps as
above: change the mapping to MapAll?=BBB DATA,
trace the routing attempt and adjust the mapping
according to your findings.
