Introduction to Cisco IPT

Based on Cisco® Unified Communication Manager technology, Cisco Internet Protocol Telephony (IPT) provides medium-sized and large businesses with cost-effective and feature-rich IP telephony solutions.
OR Based on Cisco® Unified Communication Manager technology, Cisco Internet Protocol Telephony (IPT) transmits voice, video and data applications over a single network, saving you costs and increasing employee productivity.

What is Cisco IPT?

Traditionally, enterprise communication takes place on two separate networks: Voice and Data. However, business requirements often force these networks to interoperate. By converging these networks, we can now integrate voice, data and video applications into one single network, saving costs and increasing productivity.

Cisco Internet Protocol Telephony (IPT) does exactly this. It replaces the standard public switched telephone network (PSTN) by using the internet to transmit audio between two or more users in real time and allowing users to communicate through an IP phone. This means that the Cisco Architecture for Voice, Video and Integrated Data (AVIDD) component of the IPT product transmits voice, video and data over a single network.

Designed for medium-sized to large businesses and government enterprises, Cisco IPT helps you to take full advantage of your existing IP networks to securely and cost-effectively deliver converged voice, video and data applications to your workforce, no matter where they are located.

Cisco IPT includes IP telephony, call processing software, Unified Communications, IP video and audio conferencing, a customer contact centre, voice infrastructure, network management applications and security solutions. The product is deployed either as a single site, a multi-site with a centralised call control or a multi-site with distributed call control. See below for more information.

How Will Cisco IPT Benefit My Business?

Make calls over the internet

  • The IP telephone increases personal and team productivity
  • It is virtually operated. An IP phone registers itself whenever it is moved, so users can plug in a receive calls, regardless of their location.
  • The IP telephone costs less to deploy and maintain.

Install a phone onto your computer

  • IP softphones allows your employees to install telephone technology onto their laptop or desktop.

Enjoy a centralised voice service

  • Extend the functionality of voice, video and data solutions to remote office locations without costly investments.

Manage calls

  • Cisco IPT gives you complete control of originating, routing and terminating calls.

More About Cisco IPT

Cisco IPT includes the following components:

  • CallManager:
  • This serves as the software-based, call-processing component of the solution based on Cisco AVVID. The CallManager provides signalling and call control services to the products telephony applications and third-party applications. The CallManager performs numerous functions:

  • Call processing

  • Signalling and device control
  • Dial-plan administrations
  • Phone-feature administration
  • Directory services
  • Operations, administration, management and provisioning (OAM&P)
  • Acts as a programming interface to external voice-processing applications such as Cisco SoftPhone, Cisco IP Interactive Voice Response (IPIVR), Cisco Personal Assistance, and Cisco CallManager Attendant


  • Local Area Network (LAN)/Wide Area Network (WAN) infrastructure
  • Routers and switches
  • Unify (Unified Messaging)
  • IP Telephones
  • Rich media

BCX implements Cisco IPT with the following deployment models:

  1. Single Site: A single site deployment model consists of a Call Manager located at a single site or campus. No voice services are provided across the IP WAN. Calls beyond the site LAN breakout at a gateway located at the site and are carried across the public switched telephone network (PSTN). The below figure shows a rudimentary single site deployment. For a more detailed deployment description, refer to the Cisco® Unified Communications Solution Reference Network Design (SRND).

  2. Multi-site with centralised call control: A multi-site deployment model with a centralised call control consists of a single Call Manager, typically located at a head-office site, which provides telephony services to multiple sites across an IP WAN. Both voice traffic and call control signalling are carried across the IP WAN. In the event of WAN failure, branch IP phones at affected sites re-register with a voice-enabled branch router. On-site calls can be made and received, possibly with a reduced feature set and calls to other sites are routed via the PSTN. The below figure shows a rudimentary multi-site deployment. Refer to the Cisco® Unified Communications SRND for a detailed deployment description.

  3. Multi-site with Distributed Call Control A multi-site deployment model with distributed call control consists of multiple Call Managers located at independent sites distributed across an IP WAN. In the event of a WAN failu
