We upgraded the phone firmware for our 7941/7961's to SCCP41.8-3-2SR1S. We have about 9 7941's that are having issues configuring an IP and registering with CCM 4.2(3).
I tried to reset one phone to factory defaults and now the screen lists "Upgrading" and just sits there. Any suggestions for this, also for other phones that say "Configuring IP" what should be tried. All other 7941/7961's work fine (about 213 of them).
