A user fails to leave incoming fax messages through the PRI trunk while intra-office fax messages are normal.
Step 1 Check whether the current media resource board is an MRS board and the fax mode is T.38. If yes, upgrade the MRS board to the V100R003 version or change the fax mode to transparent transmission.
Step 2 If the fault persists, contact Huawei technical support engineers.
The possible cause is that the MRS board in V100R002 does not support T.38 faxes.
MRS boards on the SoftCo in the V100R002 version do not support the T.38 fax mode. MRS boards on both the SoftCo and U1980 in the V100R003 version support the T.38 fax mode.
