l If such alarms or events are generated, clear these alarms or events to rectify the fault
according to the relevant guide. Then, proceed to Step 2.
l If such alarms or events are not generated, go to Step 3.
NOTE
The related alarms or events include the following:
l 0x38100005 DSP resources for voice services are insufficient
l 0x3b000002 Remote blocking
l 0x1a010001 H.248 interface interruption
l 0x13010001 Communication between the VAG and the SIP proxy server is interrupted
Step 2 Pick the phone off the hook again and check whether a dial tone is heard.
l If a dial tone is heard, go to Step 16.
l If no dial tone is heard, proceed to Step 3.
Step 3 Run the display protocol support command to query the current used voice protocol.
l If the H.248 protocol is used, proceed to Step 4.
l If the SIP protocol is used, go to Step 13.
Step 4 In the H.248 mode , run the reset coldstart command to reset the MG interface and make the
subscriber register again. If registration is successful, run the display pstn state command in
the global config mode to check whether the service management state (CTPAdmState) of the
POTS port is StartSvc.
CAUTION
In resetting the MG interface, subscriber services carried on this interface will be interrupted.
Therefore, before resetting the MG interface, ensure that no users under this interface are running
services.
l If CTPAdmState is StartSvc, go to Step 14.
l If CTPAdmState is not StartSvc, proceed to Step 5.
Step 5 In the H.248 mode, run the display if-h248 attribute mgid command to check whether MG
interface attributes are the same as those configured on the MGC.
l If MG interface attributes are the same as those configured on the MGC, go to Step 7.
l If MG interface attributes are different from those configured on the MGC, run the if-h248
attribute command in the H.248 mode to modify MG interface attributes to be the same
as those configured on the MGC. Run the reset coldstart command to reset the MG
interface. Then, proceed to Step 6.
Step 6 Pick the phone off the hook again and check whether a dial tone is heard.
l If a dial tone is heard, go to Step 16.
l If no dial tone is heard, proceed to Step 7.
Step 7 In test mode, run the pots loop-line-test command to perform the POTS subscriber loop line
test with the phone on the hook.
l If the test result (shown in Conclusion) is Normal, the subscriber line and the phone are
normal. Then, go to Step 9.
