Configuring the H.248/MGCP-based VAG Service

According to the data plan, configure  Huawei MA5600    standard VLAN 20 as the media and signaling upstream VLAN, add upstream port 0/19/0 to the VLAN, and configure the IP address of the Layer 3 interface to 10.10.10.10, which facilitates the configuration of the media and signaling IP address pools.
huawei(config)#vlan 20 standard
huawei(config)#port vlan 20 0/19 0
huawei(config)#interface vlanif 20
huawei(config-if-vlanif20)#ip address 10.10.10.10 24
huawei(config-if-vlanif20)#quit
Configure the media and signaling IP address pools.
Add the IP address of the VLAN Layer 3 interface configured in the previous step to the media and signaling IP address pools respectively. Therefore, the media and signaling IP addresses used for the services can be selected from the IP address pools. According to the data plan, IP address 10.10.10.10 is added to the media and signaling IP address pools, and the gateway IP address corresponding to the media IP address is 10.10.10.1.
huawei(config)#voip
huawei(config-voip)#ip address media 10.10.10.10 10.10.10.1
huawei(config-voip)#ip address signaling 10.10.10.10
huawei(config-voip)#quit
Add an MG interface.
Add an MG interface for the MG to communicate with the MGC, which ensures that the MGC can control the call connection through the MG interface. According to the data plan, add MG interface 0, and configure the interface attributes.
huawei(config)#interface h248 0
  Are you sure to add MG interface?(y/n)[n]:y

Configure the TID template of the PSTN users on MG interface 0.
Configure the TID generation mode. According to the data plan, the terminal prefix of PSTN users is huawei, and the TID template adopts layering template 6.
 NOTICE:
The Huawei MA5683T   MA5603T/MA5608T requires that the terminal prefixes of PSTN users, ISDN BRA users, and ISDN PRA users on the same H.248 interface be either the same or different. Note this when configuring the terminal prefix.
