SPA9000 Field Reference Voice tab B Phone Config XML Use LVS_PROXY CTI Enable XML configuration to be served to the phones when they request the init_$MA.xml file from the SPA9000 during their first-time initialization (either a brand-new phone or after a factory reset). If this parameter is empty, the SPA9000 serves the normal auto-generated startup XML configuration file to the phone instead. The purpose of this parameter is to facilitate ITSP provisioning of new phones remotely. ITSP can simply include a default phone profile rule parameter in this parameter so that the phone can obtain it from the SPA9000 on initial power-up. For example: https://www.itsp.com/init/spa$MA.cfg Do not include .... The SPA9000 automatically adds them when serving the configuration file to the phones. Default: blank If this option is yes, the SPA9000 uses the hostname LVS_PROXY instead of its IP address in the Profile_Rule parameter that is served to the phones when they request init_$MA.xml during first-time initialization (when is not specified). On reboot, the phones resolve the LVS_PROXY by querying the LAN via multicast. The SPA9000 replies to the query with its actual IP address. This allows the SPA9000 to use a dynamically-assigned IP address that is not fixed. Make sure that the phones have a compatible firmware that understands that LVS_PROXY is a special hostname. For SPA-941/942/921/922/901, use 4.1.12 or later; for SPA-841, use 3.1.6(KS) or later. Enables or disables the Computer Telephone Interface feature provided by some servers. NOTE If you have a SPA962 with a SPA932 console, enable CTI to support busy lamp field (B LF). SPA9000 Voice System Administration Guide 223
