H.248-based VoIP service Configure Huawei OLT:
Service Requirements:
In an office located in China, the MA5600T/MA5603T/MA5608Tthat adopts the H.248 protocol is newly deployed. Data plan and configuration, however, are not performed on the MGC (softswitch) connected to the MA5600T/MA5603T/MA5608T. The MA5600T/MA5603T/MA5608T is required to provide the following VoIP services: [boxads]
- The common phone services are provisioned to 32 users (phones 0-31).
- The polarity-reversal accounting is adopted.

Prerequisite:
- According to the actual network, a route from the MA5600T/MA5603T/MA5608T to the MGC must be configured to ensure that the MA5600T/MA5603T/MA5608Tand the MGC are reachable from each other.
- Electronic switch 0 must be in location-1(indicating that the system goes upstream through only the upstream board). Electronic switch 1 must be in location-0(indicating that the VoIP service is supported). For details about how to configure the electronic switch, see electro-switch.
Procedure:
Step 1: Add the upstream VLAN interface.
According to the data plan, configure 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.
