+You can upgrade from an old SCCP firmware to the latest SIP firmware in one pass.
+**IMPORTANT NOTE!**
+<del>It seems that after this upgrade TFTP does not work any more, and you cannot upgrade the firmware again, nor load config from a centralized server.</del>
+It is not true, i was having trouble with the tftp server. If it tries to send pxe (netboot), then the phone DOES NOT ask the tftp server for nothing. So I suppose that also official upgrade procedure (readme file) works. Will check.
 Version of the previous firmware CP7912010300SCCP.....?
