shows that the phone set of the callee can ring, which means that
communication between IAD and SoftX3000 and that between
TMG8010 and SoftX3000 are normal.
The call flow of the IAD subscriber is “IAD--TMG8010—other
carriers”. Since calls from the IAD to a non-local TMG8010 is normal,
communication between IAD and non-local TMG8010 is normal.
Since calls from the IAD to other local carriers are abnormal, the
problem should be that communication between IAD and local
TMG8010 is abnormal.
Check the IP address settings of the IAD and TMG, you can see
that the IP address of the IAD is set to 10.14.96.103/26, while that of
the TMG8010 is set to 10.14.96.101/29. The setting of the mask of the
TMG8010 is too low, which leads to communication failures between
TMG8010 and IAD.
8.4.3 Processing Procedure
According the fault phenomena and causes analyzed above, the
processing procedures are as follows.
1) The address of the SoftX3000 can be pinged through from
both the IAD and the TMG8010.
2) Make the IAD and the TMG8010 ping each other. If they
cannot be pinged through, it means the circuit is not through.
3) Modify the mask of the TMG8010 to 26 digits. Then the fault
disappears.
