Procedure 17
TestingESDN usingan SRG telephone
Step Action
1For IP Phones:
a. Dial the ESDN on an SRG IP Phone in Local Mode.
The calls must go out on the emergency trunk(s) in the branch
office.
b. Dial the ESDN on an SRG IP Phone in Nor mal Mode.
The calls must tandem over the Virtual Trunkto the branch office
and go out on the emergency trunk(s) in the branch office. The
following configuration problems can occur:
•The call can receive overflow tones. Use LD 96 to view the
digits sent to the Virtual Trunk (ENL MSGO dch#).
•If the digits look correct on the main office, the NRS might
not be properly configured. If the NRS rejects the call, a
diagnostic message is displayed on the NRS console.
•If the call makes it to the correct branch office (check that
it is not going to the wrong node if the NRS is configured
incorrectly), the branch office is probably rejecting it because
it does not know the digit string.
2For analog (500/2500-type) telephones, dial the ESDN on an SRG
analog (500/2500-type) telephone.
The calls must go out on the emergency trunk(s) in the branch office.
