I am having some trouble getting two of the three Mitel 5055 SIP phones I purchased recently to register on Asterisk PBX. One of them works perfectly, and it has firmware version The other two have a newer version and don't seem to want to register. I've verified the password and SIP username on both more than once and I cannot figure it out. I'm stuck at them flashing *NO REG* on the screen and it is going to give me an aneurysm. Does anyone have access to the firmware file for the 5055, or might know a solution to this issue? Thanks a bunch.
