Re: converting SIP to SCCP

I still don't see there what you say does happen.
Actually, Ryan says:

   In the process of recovering the phone application the first thing
   the phone will do is load whatever the default load on the server
   DHCP is pointing it to. If that's a SIP load you get SIP and if it's
   SCCP then you'll get SCCP. After the default load is obtained the
   phone will reboot to it and then proceed with a normal boot process.
   If the phone is still provisioned in CUCM (and DHCP option 150 is
   pointing to the correct server) then it will load whatever load it's
   SEPmac.cnf.xml file points to. If this is a different load than what
   the phone got via the default file then it will proceed to upgrade
   again.

...which is inline with what I said: the configuration tells the phone
what load it SHOULD be running, and the phone will try to get itself
updated.
If the phone is not provisioned, then the configuration comes from a
default one (given that option 150 points to a valid TFTP server).
If the phone can not get a config, it will eventually desist and use the
remembered one.
