9 Troubleshooting
VoIPBox DSL / VoIPBox BRI – version 21.0.009
Page 201
9.1.6
ISDN port not loaded correctly / not active
Other issues that can inhibit ISDN remote access relate to the
ISDN interface.
Reasons
|
PRI only: The CRC4 mode does not match the peer’s
CRC4 mode.
|
The ISDN cable pin assignment is wrong.
|
The TE or NT port configurations in the
pabx.cfg
file are
missing or wrong.
Symptoms
|
The system cannot be accessed from remote using
ISDN.
|
No calls are possible.
Solution
|
Access your system with GATE Manager and go to port
status.
|
Verify that layer 1 of your ISDN port is active. If not, open
pabx.cfg
and examine the ISDN controller configuration
for the correct CRC4 mode (PRI only). The CRC4 mode
needs to comply with the mode of the PRI port’s peer. If
the peer has CRC4 switched on, the ISDN port also needs
to have it switched on (controller entry CRC4). If the peer
has CRC4 switched off, the ISDN port also needs to have
it switched off (controller entry DF). Try to change CRC4
from on to off or from off to on, reboot the system and
check if this addresses your problem.
Example 9.1
PRI controller with CRC4 and DF
Controller00=9 TE S2M DSS1 CRC4 ;PRI port to DTAG with CRC4 on
Controller01=10 NT S2M DSS1 DF ;PRI port to PBX with CRC4 off
