PBX Configuration
- Overview of PBX
- Configuration Process for PBX
This section describes the process for configuring voice service data on the PBX. In the configuration process, optional tasks and subtasks are performed according to your site requirements. - Preparing for the PBX Configuration
Before configuring the PBX, verify the hardware deployment and loaded license. In addition, plan required data for subsequent configuration tasks. - Licensing Requirements and Limitations for PBX
- Configuring Basic PBX Information
This section describes how to configure basic information so that the device can work in PBX mode. Such data is used for subsequent service configuration. - Configuring a SIP Server
This section describes how to configure parameters of a SIP server, including the IP address, URI, and home domain. SIP server is an important entity in the SIP protocol architecture. The PBX can function as the SIP server to accept registration information of SIP users, save the information in the address information database, and manage and maintain users' registration information. - Configuring Toll Fraud Prevention
You can configure limiting conditions on the PBX to prevent extra expenses due to call fraud. - Configuring a PBX User
You can configure different types of PBX users according to actual networking and user planning. Terminal users on the PBX contain POTS, SIP, and ISDN users. - Configuring a Call Prefix
After intra-office and inter-office prefixes are configured on the PBX, intra-office users can call each other, and intra-office users can call inter-office users. - Configuring Number Change
This section describes how to configure calling/called number change, long and short codes, and number mapping. - Configuring Trunk Groups
A trunk group is used to transmit signaling and media data between central office, and is used to constitute a route. In TDM scenarios, a trunk group is a set of trunk circuits with the same attributes. Generally, a group of trunk circuits with the same attributes in the same direction are called a trunk group. - Configuring a Call Route
A call route defines routing rules for outgoing calls, and is bound to a call prefix and a trunk group. After a call route is configured, the PBX can correctly route outgoing calls. - Configuring the Default Call Route
The default call route defines routing rules for inter-office calls, and is bound to a trunk group. A call for which no prefix can be matched is routed out through the default call route. - Configuring Services
- Advanced Configurations
This section describes special topics including number change, call limiting, and intelligent routing. - Configuring the Signaling Proxy and Media Proxy
The PBX media proxy and signaling proxy implement address translation between network segments and enable signaling and media streams to traverse NAT. - Configuring SIP PRA Agent Registration and SIP AT0 Agent Registration
- Follow-up Procedure for PBX
After completing all the configurations, provide user information, server IP addresses, and documents to the customer. - Maintaining PBX
