Summary of Contents for Avaya S8300

  • Page 1 Avaya and Cisco Telephones - Issue 1.0 Abstract These Application Notes describe a configuration, including, Avaya Communication Manager, a Cisco 2811 Gatekeeper, and Cisco CallManager that was verified for a customer proof of concept request. In this configuration, Avaya Communication Manager and Cisco CallManager are registered with the Cisco 2811 Gatekeeper, which provides call control between Avaya Communication Manager and Cisco CallManager.
  • Page 2 Figure 1 depicts the network configuration utilized for these Application Notes. In Location A in Figure 1, the Avaya G350 Media Gateway with S8300 Server provides both H.323 Gateway (GW) and Gatekeeper (GK) functionality. In Location B, the Cisco 2811 access router is configured as an H.323 Gatekeeper, and the Cisco CallManager is registered with it.

  • Page 3: Equipment And Software Validated

    The following equipment and software were used for the sample configuration provided: Network Component Software Version Avaya Communication Manager 3.1.2 (634) S8300 Server with G350 Media Gateway Avaya G350 Media Gateway 26.31 Avaya 9600 IP Telephone (H.323) 1.2.1 Avaya 4620 IP Telephone (H.323) Cisco 2811 Gatekeeper 12.4(2)T5 (IP Voice)

  • Page 4: Ip Node Names

    Communication Manager. It is assumed that appropriate license and authentication files have been installed on the S8300 Server. It is also assumed that the network IP address on the S8300 Server has been configured to 22.1.1.22/24 and the IP address on the G350 GW has been configured to 22.1.1.23/24.
  • Page 5 Calls above the specified limit will not be permitted, and may be re-routed to a different path. The bandwidth usage is based on the packet size and codec selection. Avaya supports IP Call Admission Control via Bandwidth Limits (CAC-BL). Codec set 2 is used for calls between regions 1 and 2.
  • Page 6 Calls above the specified limit will not be permitted, and may be re-routed to a different path. The bandwidth usage is based on the packet size and codec selection. Avaya supports IP Call Admission Control via Bandwidth Limits (CAC-BL). Codec set 2 is used for calls between regions 2 and 1.
  • Page 7 Cisco 2811 GK, a signaling group for outbound traffic must be configured. Note that the IP address of the Avaya S8300 Server (procr) functions as an IP address for both H.323 GW and Use the command add signaling-group <group number> to create a signaling group. The Near- End Node Name and Far-end Node Name are configured to the procr and Cisco-GK respectively.

The Cisco 2811 Gatekeeper will send the call setup message to the appropriate gateway, for these Application Notes, Cisco CallManager.
  • Page 11 To reduce the configuration required, the Far-end Node Name can be left unspecified, or an inbound signaling group can be configured for each GW from which Avaya Communication Manager should accept calls. The following screen shows the configuration for inbound signaling group 21.
