Maximum phones and directory numbers
max ephone & max ephone-dn
Firmware load files
share the phone loads with “tftp-server” command
"tftp-server flash:/phone/7942-7962/apps42.8-3-1-22.sbn alias apps42.8-3-1-22.sbn"
load phone loads under telephony-service configuration mode
"load 7962 SCCP42.8-3-2S" (*** DO NOT include the suffix ".loads" or ".bin", I spent lot of time for troubleshooting when I lab it the first time.)
Even you specified the wrong “loads” or “bin” file, the phone can still register to CCME with error message “File NOT Found….”.

"ip source-address x.x.x.x”
