BCM 3.6 and SRG 1.0 Wireless IP Telephony Patch Executive Summary In general, the objective of BCM 3.6/SRG 1.0 WLAN IP Telephony patch is to provide Unified Manager and DHCP Server support for Wireless IP Handset 2210 and 2211. This patch will be rolled into the factory build as at the next BCM release, BCM 3.7. This document contains release notes that describe the new behaviors introduced by BCM 3.6/SRG 1.0 WLAN IP Telephony patch as well as the limitations that apply to the proposed solution.

BCM 3.6 and SRG 1.0 Wireless IP Telephony Patch Enhancements by component 1. Unified Manager GUI 1: To input the TFTP and SVP server IP addresses, in Unified Manager, navigate to Services>>DHCP and click on the Global Options tab. Two new prompts, “TFTP server” and “Netlink SVP server” (a.k.a. WLAN IP Telephony Manager 2245) will be displayed. These prompts are used to input the TFTP and SVP server IP addresses. Please refer to GUI 1. The configured IP addresses are sent in DHCP.
BCM 3.6 and SRG 1.0 Wireless IP Telephony Patch GUI 2: 2. Telephony Services There are two modes in which the i2210/i2211 wireless telephone can operate: DHCP enabled or Static IP. DHCP will use Dynamic Host Configuration Protocol to assign an IP address each time the wireless telephone is turned on. If DHCP is enabled, the wireless telephone also receives all other IP address configurations from the DHCP server.
BCM 3.6 and SRG 1.0 Wireless IP Telephony Patch The DHCP server can be on either side of the firewall according to the site administrator’s preference. The DHCP server is optional if the administrator wants to statically configure the handsets and SVP server. The 2210 and 2211 can have their IP related parameters configured manually or via a DHCP server (RFC1541 and RFC 1533). Any DHCP server can be used but it must support the following capabilities.
BCM 3.6 and SRG 1.0 Wireless IP Telephony Patch addresses as big as the number of phones supported must be marked as unavailable for distribution by the DHCP server. When multiple WLAN's are connected to a single WSS, the DHCP server may require specific configuration modifications. Please refer to the documentation for the specific WSS being used for any special DHCP configuration requirements. 3. QoS The i2210/i2211 wireless sets operate on 802.11b protocol. The 802.
BCM 3.6 and SRG 1.0 Wireless IP Telephony Patch replaces the SVP protocol number, 0x77, with the UDP number, 0x11. For packets going from the network to the handset the protocol number is changed from 0x11 to 0x77. SVP is required for QoS because the current IEEE 802.11b wireless LAN standard provides no mechanism for differentiating audio packets from data packets. This standard is undergoing revision to version 802.
BCM 3.6 and SRG 1.0 Wireless IP Telephony Patch initial release. At the next BCM release they will be included as part of the online BCM core documentation: BCM Wireless LAN IP Telephony Installation & Configuratio n Guide BCM Wireless LAN Handset 2210/2211 User Guide. 5. 2210/2211 limitations • • • • • • i2210/i2211 jitter buffer size cannot be adjusted. Any changes in unified manager will not be enforced by the handset. i2210/i2211 does not support RTCP i2210/i2211 does not support G.
BCM 3.6 and SRG 1.0 Wireless IP Telephony Patch • • • o Verify all devices connected to the IP Telephony Manager 2245 are configured correctly (no duplex mismatch found) o If all configurations are correct, re-boot the IP Telephony Manager 2245. The error message should be cleared Q00953132 - Display does not show "Local Mode" when Spectralink under control of SRG Q00992252 – When using the Hotline feature on 2210/2211, pressing the release key shortly after the ringback tone starts will have no effect.
