2. The interface attribute parameter is incorrect.
Handling Proce
ss:
1. Run the following command to check the transaction reliability parameters of the H.248
stack:
huawei(config-if-h248-0)#h248stack tr
The parameters are set correctly for H.248 retransmission.
2. Run the following command to check interface attributes:
huawei(config-if-h248-0)#if-h248 attribute transfer
A difference exists in this UA5000 version from earlier versions. In addition to TCP and UDP,
the parameter alf/udp is added in this version. In this version, to enable H.248 retransmission,
the alf/udp attribute must be selected, while in other versions, the conventional configuration is
UDP where the retransmission mechanism is also effective.
3. Modify the interface attribute to alf/udp and reset the interface. The retransmission failure is
rectified.
