2.3.10 When the IAD Is Connected to the Local PSTN Network
Through the FXO Port, an Incorrect ID That Is Bound to the FXO
Port Causes Incoming Call Exceptions
Symptom
Network: SoftCo-IAD-PSTN
A SoftCo user makes an outgoing call to a PSTN user through the FXO port on the IAD. An
outer-office user dials the PSTN number to make an incoming call to the PSTN user through
the FXO port. This implements the number retention service. The outer-office user hears the
ring back tone twice before hearing the announcement indicating that the number dialed does
not exist.
Cause
The possible cause is incorrect data configuration.
Solution
Step 1 Verify that a correct ID is bound to the FXO port. The ID bound to the FXO port must be the
DN, that is, SoftCo number, not the EID.
The ID configured on the FXS port is the SoftCo EID, but the ID bound to the FXO port is the DN.
Generally, the EID is the same as the DN; however, there are some exceptions, especially when the
virtual PBX exists. For example, the intra-office number is 1000, but its EID is 2000.
Step 2 Configure the ID bound to the FXO port. For example:
TERMINAL(config)#sip user 0 id 2000
TERMINAL(config)#sip user 8 id 1000
Step 3 Check whether the fault is rectified.

If yes, the procedure ends.

If no, go to Step 4.
Step 4 Contact Huawei technical support.
