Hello Everyone, Firstly, thank you for the assistance to date.  I think I'll need to engage a CISCO engineer that's familiar with telephony to come on-site and correct the problem.  That assumes the phones can actually be configured correctly to oper...

Yes that’s correct. FUBAR indeed.Apparently I just need a copy of Cisco Unified Comms Manager and I can change the phone from Enterprise to MFF.Are you familiar with that process?

Now they just want to replace the phones with Yealink 45G things. I don’t what them.BTW – what’s your on site or remote tech support fee?Thanks, Frank

PID version on the handset I have is v04.I’d prefer to try and convert this handset than use Yealink crap. How do I do this? Point the update/change at the relevant handset IP addy?Thanks so much for your help – I owe you one.Frank

Thanks – what’s the cost to do this? So far we’ve spent over $1.5k to do this with new PoE switches, and the 8851 handsets x 2.
