Product Substitution Options

The recommended replacement for the Cisco CSR is the Cisco NAM (Table 3). The Cisco NAM Package for IP-Based Least Cost Routing (LCR) drops into the network in the same position as the Cisco CSR (on top of the gatekeeper through the Gatekeeper Transaction Message Protocol [GKTMP] interface on the Cisco gatekeeper), and provides the Cisco CSR capabilities and more.

Cisco Network Applications Manager Package Details

The Cisco NAM is a flexible, highly scalable software application that supports a portfolio of services for both time-division multiplexing (TDM) and IP networks. These services range from simple to complex, enabling service providers to capitalize on a multitude of business opportunities across their customer base. Specifically, it provides a service continuum that includes:

  • Advanced routing capabilities, which compare favorably to the call routing capabilities of the Cisco CSR
  • Support for automatic call distributors (ACDs)
  • Support of Cisco IP Contact Center (IPCC)
  • Full-featured computer-telephony integration (CTI)
  • Integrated interactive voice response (IVR) option
  • Integrated customer relationship management (CRM) option
  • Web collaboration option
  • E-mail response management option
  • Connectivity to Public Switched Telephone Network (PSTN) and voice-over-IP (VoIP) networks


A special NAM package for routing applications in VoIP networks is available. It includes:

  • One NAM server with 100 calls-per-second throughput for LCR applications. For limitations see below.
  • One gatekeeper (supporting GKTMP) network interface card (NIC) for use with this limited NAM only
  • Either Structured Query Language (SQL) gateway or application gateway for interfacing with an external database or application (database and application not included; assistance in integrating with and customizing for the customer's preferred database is available from Cisco Professional Services)
  • Two user provisioning and reporting systems (admin workstations)

Ordering Information

Cisco NAM Package for IP-Based LCR Applications

Part Number: NAM-LCRPAC

Additional 100 calls-per-second throughput for Cisco NAM Package

Part Number: NAM-LCR100CPS or NAM-LCR100CPS=

Additional throughput capacity can be added by ordering part number NAM-LCR100CPS, which will give customers the ability to handle up to 300 calls per second in total. Please note—the package is subject to the following limitations:

  • No Cisco Intelligent Contact Management devices or other NAM applications can be connected to this NAM.
  • No other NICs than the gatekeeper (GKTMP) NIC can be deployed with this NAM.
  • The gatekeeper NIC supports Cisco IOS® Software Release 12.1(5)XM, which is supported on the Cisco 3600 and Cisco 7200 Series routers.
