We're in the process of moving from an external VOIP provider (using MINET) to an internal FrePBX (using SIP). The phones have been just chugging along for years, and so the SIP conversion has hit some speedbumps. For example, some phones will take the SIP load, and some will not. Turns out that they have differing levels of software on them a,d some will accept the last SIP load (v8), and some need V5 then V8 (or V5 then V7 then V8).
Anyway, one phone got into quite a struggle, displays a message about updating flash, and stays stuck at 0%. We have had no joy at doing a phone reset, or any other intervention.
Is there some sort of a hard reset which can get it out of the current state, and into a happier place? Or have we bricked it?
