Description

A campus LAN VoIP system based on IBX1000

technical field

The invention relates to the field of campus construction, more particularly, to a campus local area network VoIP system based on IBX1000.

Background technique

With the development of multi-service, multi-access, high-quality, and high-guarantee data networks in order to adapt to the campus network, and taking into account the improvement of the utilization rate of network resources, the reduction of PSTN private network in the enterprise network, campus network and other internal parks It is imperative to deploy VoIP in the campus network because of the high frequency of use and the high call charges generated. PSTN is based on circuit switching, and it is increasingly unable to support proliferating services, and it cannot be integrated with the mobile network. Because VoIP promotes the utilization of network resources and reduces the cost of voice services, it is developing rapidly around the world. Although there are still many problems to be solved in terms of voice quality, lack of IP addresses, power supply, numbering system, etc., the development of technology itself and the increasing prompting of people's needs make the technology need to be constantly updated, which also promotes the use of VoIP in campus networks and campuses. Internet and other intranets are developing rapidly. At present, the 4G mobile communication technology widely used in the world is named VoLTE, that is, Voice over LTE. It is also a transmission technology to carry data and voice services over an IP data network, providing high-quality audio and video calls.

At present, the local area network of many schools is relatively complete, but the fixed line still uses dedicated telecommunication lines, which increases a lot of telephone bills for the school. The implementation methods such as configuration are explored, and considering the construction cost and the difficulty of coordination and planning in all aspects, we strive to practice first on the floor where the equipment is located and even in the entire building. On the basis of protecting the original data network, only a small amount of network connection equipment (switches, routers, etc.) is added as much as possible, and the existing commercial softswitch equipment is used to build the training room and even the campus VoIP network.

Voice is analog, and IP networks transmit digital signals, so in order for routers to be able to handle voice, devices that can interpret analog signals into a digital format that can be transmitted over IP networks must be installed. The Voice Network Module (VNM) is designed to do this, and each router needs at least one VNM to handle voice traffic. In order to implement VoIP on Cisco routers, it is first necessary to understand the different types of hardware and router ports required by VoIP technology. Voice network modules and voice interface cards use VoIP commands to enable voice communication on Cisco routers. Without purchasing a relatively expensive IP-based voice server, you can choose a router equipped with a voice function module to build VoIP between multiple campuses in an enterprise or organization. This article chooses Cisco's 2811, which is also considered to be simulated in the Cisco Packet Tracer simulator. A variety of Cisco routers can be equipped with voice function modules, such as 18, 28, and 38 series all have corresponding functions. The present invention only needs to do the corresponding configuration on the above to realize VoIP. The built cross-network segment realizes VoIP topology diagram as shown in shown in Figure 3.

The left side of Figure 3 shows a campus of the school, and the right side is another campus, which is connected through an IP network in the middle. In this environment, 2811 is the most core device, and most of the configurations of the present invention are built on it. Since the ports of the router are very valuable, the present invention selects a common layer-2 switch to provide more interfaces. There are many types of telephones here, including IP telephones, analog telephones, and softphones installed on PCs and PDAs. PCs and IP telephones can be directly connected to the switch, but analog telephones require a home-type access gateway to connect to the switch. Switch, using wireless AP to provide mobile office or PDA device supporting soft IPhone in the very flexible access network, after completing the corresponding configuration, the two campuses can communicate arbitrarily.

In this implementation, the key configurations in the campus include the configuration of creating a DHCP address pool on the router side and enabling the voice server, followed by the configuration of creating a phone number and binding the phone number to the phone. After completing these configurations, the campus can be tested. Communication. To achieve cross-campus communication, you also need to configure the dial-up phone pair. The configuration of the dial-up phone pair is highlighted here. The key configurations on the 2811 router in campus 1 are as follows.

Router(config)#dial-peer voice 1voip

Router(config-dial-peer)#destination-pattern 8888....

Router(config-dial-peer)#session target ipv4:192.168.2.254

To enter dial-peer configuration mode, use the dial-peer voice TAG{voip|pots|ivr} global configuration command, where TAG is the ID number of the dial-peer the user wants to create or configure. Unique decimal number. Its value ranges from 1 to 2147483647, which is 2^31-1. Note that this ID number is only unique to the local router, so this number can be used on another router without affecting the current configuration.

voip is a dial-up pair connected through an IP network, pots is a dial-up pair connected through a traditional telecommunication network, and ivr is a dial-up pair connected by an interactive voice response IVR connection type. By default, this parameter is all, which means all dial-up pairs are selected. It should be noted that if the ID entered by the user already exists in the dial-peer table and the pattern matches, enter the dial-peer configuration mode to configure and modify the corresponding dial-peer; and when the ID entered by the user is in the dial-peer table already exists, but the pattern does not match, the user will be prompted whether to create a new dial-peer and replace the original dial-peer. If the user selects "yes", a new dial-peer will be created and the original dial-peer with this ID will be created. Delete the dial-peer, and then enter the dial-peer configuration mode for configuration. If "no" is selected, it will return to the global configuration mode; if the ID entered by the user does not exist in the dial-peer table, create a new dial-peer and enter the dial-peer configuration mode to configure it. When the user enters the nodial-peer voice command, if the dial-peer with the specified ID exists, it will be deleted; otherwise, the user will be prompted; if all is selected, all dial-peers will be deleted after being prompted for confirmation. Only one user can configure dial-peer at the same time, otherwise, if multiple telnet users configure dial-peer at the same time, it will cause configuration errors.

Use the destination-pattern 8888.... command to define the phone number or number prefix called by this peer, matching an eight-digit phone number prefixed with 8888, each dot is a wildcard, representing a phone number. Use the session target ipv4:192.168.2.254 command to match the peer, that is, the remote IP host designated for processing the call. You can specify the host's IP address, domain name, gatekeeper, etc.

Similarly, the 2811 router in campus 2 can be configured similarly. You can also enter req-qos controlled-load in the dial-peer configuration mode to enable RSVP when allocating bandwidth to ensure that even if the bandwidth is congested When overloaded, the voice stream can be prioritized. At the same time, you can use the ip precedence 2 command to set the priority of the specified voip voice packet. The value range is an integer from 0 to 7. The smaller the value, the higher the priority. Enabling the above configuration ensures that voice traffic gets a specific QoS in the network.

After the above configuration, wait for a few minutes, all phones can be successfully registered and get their respective phone numbers, and then the dial-up test is performed, and the voice communication of all terminals is normal.

Enter the show ephone command in privileged mode, you can see the registration information of all phones, the phone type defined must match the real situation, the type of analog phone is ata, the type of soft phone is cipc, and the type of IP phone is 7960. The invention here is to bind the phone with the mac address first and then with the phone number. About the phone and the mac address, you can use the show ip dhcp binding command to view it in the privileged mode, and only single-line numbers are used here. Binding, in fact, based on this, multi-line number binding can be done, that is, one voice port corresponds to multiple channels, and functions such as call transfer, call waiting, and conference call can be implemented between multiple channels.

The above configuration process can complete a complete process of establishing VoIP communication on the router. When the user goes off-hook, the function of the application signaling layer of the IOS of the Cisco router is triggered. When the user dials the correct phone number, the number is determined by the dial plan. The mapping table maps to an IP host, matches the last VoIP dial-peer declaration, and leads to the end voice router. The receiving router is directly connected to the end station through the corresponding port, and then the session application will start the H.323 protocol to establish a sending and receiving channel for each call on the network, and the codec activities at both ends of the channel will occur immediately to ensure that the correct supported Compression/decompression algorithm. After the channel is established, all call progress commands and signaling are immediately sent to the receiving entity for decoding or display. When any one of the two ends of the call session sends out the "hang up" signal, the call ends, and both ends of the circuit return to the "suspend" state, waiting for another initial session to start.

The correct configuration and execution of a few commands have realized the construction of a small VoIP environment. It can be seen that what this article achieves is only to deploy and carry out business on the existing platform and IOS, and there are many underlying network elements, protocols and services. They are all responsible for the whole system to work and run in an orderly manner. When applying this deployment on a real device, take into account dial plans, number extensions, QoS over VoIP over leased lines, etc. Of course, this deployment still has its application value. For example, many schools and institutions are using PBX to process voice applications. It is wise to use this deployment to fill the "blank" area in the network to achieve dual-circuit redundancy. In case of IP Unexpected problems occur in the network. At this time, the connection to the PBX is still available, and vice versa. At this time, the difficulty of offline troubleshooting is greatly reduced, and the maintenance and repair time is completely transparent to end users. .
