7.8 Configuring the Security and Reliability of the Voice
Service
For the MA5616, the security configuration of the voice service includes the H.248-based, or
SIP-based device authentication configuration. The reliability configuration of the voice service
includes the dual-homing configuration and the emergency standalone configuration.
7.8.1 Configuring the Device Authentication
The purpose of authentication is to verify the validity of users and networks. The same
authentication algorithm is used on the MG and the MGC separately. Then, the calculation results
on the MG and the MGC are compared on either side. If the calculation results are the same, it
indicates that the authentication is successful. If the calculation results are different, it indicates
that the authentication fails.
7.8.1.1 Configuring the Device Authentication (Based on the H.248 Protocol)
This topic describes how to configure the device authentication parameters of the MA5616 to
prevent illegal devices from registering with the MGC when the H.248 protocol is used.
Prerequisites
l
The MG interface must be added successfully on the MA5616.
l
The parameters, including the encryption type, the initial key, and the DH authentication
MG ID, must be configured on the MGC. These parameters must be the same as the
parameters configured on the MA5616.
Precautions
When the MGC is Huawei SoftX3000, the authentication MG ID must be a string of more than
eight characters.
