Troubleshooting the LifeSize Gateway 153
About Problems with Inbound Calls
Make sure that the PRI line is in working order.
Disconnect the PRI line from the LifeSize Gateway and connect it to
a regular PSTN phone. Dial the number. If the phone does not ring,
the DID line is out of order.
Possible Cause There is a mismatch between the number of digits in the dial
number that the service provider sends in DID calls and the number of digits in the
corresponding E.164 addresses registered with the gatekeeper.
Recommended Action Make sure that the service provider is sending the same
number of digits in calls as specified for the DID service.
Make sure that the service provider is sending the same number of digits in calls
as specified for the DID service.
For example, if the service specifies four significant digits in the number, the
service provider must send four-digit numbers. If the service specifies seven
significant digits in the number, the service provider must sends seven-digit
numbers.
Symptom When TCS4 is used, why do TCS4 calls not reach the requested
terminal?
Possible Cause The TCS4 number might not be registered with the gatekeeper
or the LifeSize Gateway is improperly configured.
Recommended Action
Make sure that theTCS4 number is associated with an endpoint in the
gatekeeper registration table.
Make sure that the TCS4 option is enabled for the PRI or serial port.
