All of my phones have been 7960's to date but decided to add a 7970G. However I cannot get hte phone to pair up with the UC540 - instead am just getting flashing green line buttons. Have checked the CCA and it would appear that our installer may have deleted all phone loads except the one for the 7940 phones. Have downloaded both the Skinny and the SIP firmware files but cannot seem to add them - when trying to upload them the uploader can only see .ZIP file types. Have found .ZIP files on the Cisco site but neither are compatible with our UC540. Any ideas?
