Configuring Cisco Voice Over Ip 2Nd Edition' title='Configuring Cisco Voice Over Ip 2Nd Edition' />Voice Interface Configuration Configuring Voice Ports. After reading this chapter, you should be able to perform the following tasks Configure analog and digital voice interfaces as new devices are introduced into the voice path. Configure analog and digital voice ports for optimal voice quality. Voice gateways bridge the gap between the Vo. IP world and the traditional telephony world for example, a PBX, the PSTN, or an analog phone. Cisco voice gateways connect to traditional telephony devices via voice ports. Configuring Cisco Voice Over Ip 2Nd Edition' title='Configuring Cisco Voice Over Ip 2Nd Edition' />This chapter introduces basic configuration of analog and digital voice ports, and demonstrates how to fine tune voice ports with port specific configurations. Upon completing this chapter, you will be able to configure voice interfaces on Cisco voice enabled equipment for connection to traditional, nonpacketized telephony equipment. Connecting voice devices to a network infrastructure requires an in depth understanding of signaling and electrical characteristics that are specific to each type of interface. Improperly matched electrical components can cause echo and make a connection unusable.

OnNet Calls. Onnet calls occur between two telephones on the same data network, as shown in Figure 32. The calls can be routed through one or more Cisco voice. Training Programs and Courses Training, Certification, SelfHelp and Career Training. As another consideration, configuring devices for international implementation requires knowledge of country specific settings. This section provides voice port configuration parameters for signaling and country specific settings. Before delving into the specific syntax of configuring these voice ports, this section begins by considering several examples of voice applications. The applications discussed help illustrate the function of the voice ports, whose configuration is addressed at the end of this section. Voice Applications. Different types of applications require specific types of ports. Aula Internacional 2 Libro Del Alumno Pdf Descargar more. In many instances, the type of port is dependent on the voice device connected to the network. Different types of voice applications include the following Local calls. On net calls. Off net calls. Private line, automatic ringdown PLAR calls. PBX to PBX calls. Call. Manager to Call. Manager calls. On net to off net calls. The following sections describe each type and provide an illustration of each. Local Calls. Local calls, as illustrated in Figure 3 1, occur between two telephones connected to one Cisco voice enabled router.

I have a server and have been assigned a static IP by my ISP. How do I go about configuring my server to work on its assigned IP Implementing Cisco Unified Communications Manager, Part 2 CIPT2 Foundation Learning Guide CCNP Voice CIPT2 642457, 2nd Edition. As discussed here, the Cisco QInterface Signaling QSIG tunnelingoverIP feature, which provides the capability to tunnel QSIG protocol messages over an IP. This type of call is handled entirely by the router and does not travel over an external network. Both telephones are directly connected to Foreign Exchange Station FXS ports on the router. On Net Calls. On net calls occur between two telephones on the same data network, as shown in Figure 3 2. The calls can be routed through one or more Cisco voice enabled routers, but the calls remain on the same data network. The edge telephones attach to the network through direct connections and FXS ports, or through a PBX, which typically connects to the network via a T1 connection. IP phones that connect to the network via switches place on net calls through Cisco Unified Call. Manager. The connection across the data network can be a LAN connection, as in a campus environment, or a WAN connection, as in an enterprise environment. Off Net Calls. Figure 3 3 shows an example of an off net call. To gain access to the public switched telephone network PSTN, the user dials an access code, such as 9, from a telephone that is directly connected to a Cisco voice enabled router or PBX. The connection to the PSTN is typically a single analog connection via a Foreign Exchange Office FXO port or a digital T1 or E1 connection. PLAR Calls. PLAR calls automatically connect a telephone to a second telephone when the first telephone goes off hook, as depicted in Figure 3 4. When this connection occurs, the user does not get a dial tone because the voice enabled port that the telephone is connected to is preconfigured with a specific number to dial. A PLAR connection can work between any types of signaling, including receive and transmit ear and mouth E M, FXO, FXS, or any combination of analog and digital interfaces. As an example, you might have encountered a PLAR connection at an airline ticket counter, where you pick up a handset and are immediately connected with an airline representative. PBX to PBX Calls. PBX to PBX calls, as shown in Figure 3 5, originate at a PBX at one site and terminate at a PBX at another site while using the network as the transport between the two locations. Many business environments connect sites with private tie trunks. When migrating to a converged voice and data network, this same tie trunk connection can be emulated across the IP network. Modern PBX connections to the network are typically digital T1 or E1 with channel associated signaling CAS or PRI signaling, although PBX connections can also be analog. Call. Manager to Call. Manager Calls. As part of an overall migration strategy, a business might replace PBXs with a Cisco Unified Call. Manager infrastructure. This infrastructure includes IP telephones that plug directly into the IP network. Cisco Unified Call. Manager performs the same call routing functions formerly provided by the PBX. When an IP phone uses Cisco Unified Call. Manager to place a call, Cisco Call. Manager, based on its configuration, assesses whether the call is destined for another IP phone under its control or whether the call must be routed through a remote Cisco Call. Manager for call completion. Although the call stays on the IP network, it might be sent between zones. Every Cisco Call. Manager is part of a zone. Picsay Pro V1 3 5 3 For Android'>Picsay Pro V1 3 5 3 For Android. A zone is a collection of devices that are under a common administration, usually a Cisco Unified Call. Manager or gatekeeper. Figure 3 6 provides an example of a Call. Manager to Call. Manager call. On Net to Off Net Calls. When planning a resilient call routing strategy, it might be necessary to reroute calls through a secondary path should the primary path fail. An on net to off net call, as illustrated in Figure 3 7, originates on an internal network and is routed to an external network, usually to the PSTN. On net to off net call switching functionality might be necessary when a network link is down or if a network becomes overloaded and unable to handle all calls presented. Summarizing Examples of Voice Port Applications. Table 3 1 lists application examples for each type of call. Table 3 1. Voice Port Call Types. Type of Call. Example. Local call. One staff member calls another staff member at the same office. The call is switched between two ports on the same voice enabled router. On net call. One staff member calls another staff member at a remote office. The call is sent from the local voice enabled router, across the IP network, and terminated on the remote office voice enabled router. Off net call. A staff member calls a client who is located in the same city. The call is sent from the local voice enabled router, which acts as a gateway, to the PSTN. The call is then sent to the PSTN for call termination. PLAR call. A client picks up a customer service telephone located in the lobby of an office and is automatically connected to a customer service representative without dialing any digits. The call is automatically dialed, based on the PLAR configuration of the voice port. In this case, as soon as the handset goes off hook, the voice enabled router generates the prespecified digits to place the call. PBX to PBX call. One staff member calls another staff member at a remote office.
