Hi to all.
IP Phones Dialog 4422/2 and 4425/2 use an inside Processor Board (ROA 309 210/1 - R1E or R2B).
Some times I read on display these messages: "No network connection" or "ERROR! Check Addr Netmask" and some other times it's impossible to login the IP Phone (it's impossiblke to do ping).
I tried to replace the Processor Board and the problem was desappeared.
Now, it's possible to repair the Processor Board or to re-configure it?
If yes, how can do it?
If not, where can I buy the right Processor Boards?
Can you help me?

Thanx a lot in advance / Gianni

Never seen this board as an orderable spare part. You either have to swap boards, or send the phone(s) for repair.
