The AR1220V and AR1220VW support voice functions in the AR1200 series. The AR2200 series and AR3200 series support analog voice functions only when the DSP module is configured on the device. You need to purchase the 4FXS1FXO board when you need to access the POTS user on the AR1200, AR2200, and AR3200.

You need to purchase a 2BST board when you need to access an ISDN phone user on the AR1200, AR2200, and Huawei AR3200. The enterprise builds a voice communication system based on the IP network, which enables the internal voice communication of the enterprise to not generate communication costs and saves the enterprise cost.

When building a voice communication network, the AR can act as an IP PBX device or a SIP AG device, and access the POTS user (analog phone or fax) through the FXS interface, access the ISDN phone user through the S/T interface, or access the SIP UE through the Ethernet interface. User (IP phone or PC soft terminal). The uplink can access the traditional PSTN network through the FXO or E1 interface, or access the IP network through the Ethernet interface. Depending on the geographical distribution of the enterprise branch, users can choose to deploy centralized call control networking or distributed call control networking. Generally, when the enterprise branches are concentrated in the same number area, centralized call control networking can be adopted. When the enterprise branches are not concentrated in the same number area, and the number of branches is large, it is recommended to use distributed call control networking. Enterprise branch A is not in the same number area as the corporate headquarters. An IP PBX is deployed on the enterprise headquarters and enterprise branches (that is, the AR device works in PBX mode) as an egress router. The voice user of the enterprise headquarters is registered to the IP PBX device of the enterprise headquarters. The voice users of the enterprise branch are all registered to the IP PBX device of the enterprise branch. The voice user communication between the headquarters and the branch is out through the voice route between the headquarters and the branch. And the headquarters IP PBX provides call routing for each branch office to communicate. The enterprise branch B is connected to the enterprise headquarters through an IP private network. The IP PBX is deployed at the enterprise headquarters (that is, the AR device works in the PBX mode), and the enterprise branch deploys SIP AG (that is, the AR works in the AG mode). The voice users of the enterprise headquarters and enterprise branches are all registered to the IP PBX of the enterprise headquarters. The headquarters IP PBX provides call control services for all users in the enterprise.
