5325 won't load sip firmware.

[twinturbo]

I have upgraded 7 of 8 5325's to SIP with little fuss.

one however will not do it..

it first complains "L2Boot_5325........" ( this is also reported as not found by my TFTP server.

The TFTP server also complains about "BootIP5325...." not found.

The phone loads the SIP file up to "514" then complains "SIP MAIN TOO BIG" and then reboots.

Any ideas on what's up with this last one?

Cheers

This is your clue... that set is on a very old firmware, and needs to be upgraded to a mid-level release before up to what you have.

From http://www.voip-info.org/wiki/view/Mitel+SIP+Firmware

For all SIP Phone types running any software previous to Rel 7.2, this includes Rel 3.0, Rel 3.1, Rel 4.0, Rel 5.0 MUST upgrade to Rel 5.0.0.21 prior to upgrading to Rel 7.2.

Rel 5.0.0.21 MINIMUM is required as a stepping point up to Rel 7.2. Any other method of upgrade could result in corrupted Flash Memory on the SIP Phone resulting in a permanently dead phone.

In general it is important to upgrade older firmware in sequence - eg: v3 -> V4 -> V5 -> V6 etc. without skipping any releases. Failure to do this (eg: upgrading from V3 directly to V6) may brick the phone.
