170 SCOPIA 400/1000 Gateway User Guide
Resolving ISDN-to-IP Call Failure
The Gateway TCS4 option is checked and
the dialing delimiter is not a legal TCS4
delimiter. Ensure that the initiating endpoint
uses the correct TCS4 delimiter
(see the endpoint users guide).
Verify that the endpoint you are
using supports TCS4.
The Gateway IVR option is checked but
there is no endpoint with such an E.164
number on the LAN. Check that a LAN endpoint with
the same E.164 number that you
dialed during the IVR phase is
registered with the gatekeeper.
You may need to register the
LAN endpoint to the gatekeeper
with a correct E.164 number.
Check that the ISDN endpoint
DTMF generation works
properly:
Open a Telnet connection to the
Gateway.
Make a call to the Gateway IVR.
Dial the E.164 number using
DTMF tones.
Check the Telnet log for correct
DTMF digit detection.
Make a call to another properly
registered endpoint.
