Here's a clip of comments lifted from a Cisco bug list. This will be perhaps useful to those of you who have just purchased a Cisco phone off eBay. JT ------------- (1) Short problem description: Documentation on how to load SIP image on phone with skinny software (2) Longer problem description (what happens): If the phone is loaded with the Cisco Skinny code, then there is a small problem with loading SIP images that are over 4K in size. This is caused by the Skinny code having a 4K tftp buffer. So if you look at the latest images P0S3-04-1-00.bin is 449K in size, if you try and load this file the tftpboot will hang when the buffer is full. At present there is NO error message and you have to look at a sniffer trace to see the error message. (3) Possible solution (what did you expect): Information in the documentation on how to do this. (5) Workaround used currently (if applicable): A simple procedure is..... Download the SIP image P0S30203.bin and the rest of the files that are needed (OS79XX.txt/SIPDefault.cnf/SIPDefaultGeneric.cnf/ringer1.pcm/ringer2.pcm/dialplan.xml/RINGLIST.DAT) Change OS79XX.TXT file to contain P0S30203 Power cycle the phone so that it will load the new image Once the phone is loaded with P0S30203 you can then download SIP image P0S3-04-3-00.bin into the TFTPBOOT directory and either change the SIPmacaddress.cnf file to load this image, or change OS79XX.TXT file to reflect this image. Do NOT rename this file, it should appear as P0S3-04-3-00.bin otherwise the phone will continuously reload.

It seems to grab the OS79XX.TXT, upgrade to that version, and then grab the SIPDefault.cnf and upgrade to the version in there. This means you can just leave the config there, and phones will happily upgrade themselves when properly pointed (DHCP with the Boot Server option works quite nicely for me). Bonus points for inviting your friends with their Skinny phones to try them on your network. -rt -- Ryan Tucker Network Engineer NetAccess, Inc. 1159 Pittsford-Victor Road Bldg. 5, Suite 140 Pittsford, New York 14534 585-419-8200 www.netacc.net
