[cisco-voip] quick sanity check on factory reset

[Wellnitz, Erick A.]

I was just double checking because I have two bricked  7911s (one from a site and one from me testing).  Packet captures show the phone getting DHCP but no tftp traffic.  I know the DHCP scope is correct because my desk phone is using that same scope without issue.



I have a TAC case open

We covered this earlier in a fairly interesting thread, I think it boiled down to this: Whatever was the last firmware loaded on the TFTP server will be the load that the phone will try to load after a factory default reset.

If you are "testing" a new SIP load and that was the last firmware you loaded, a factory reset will force the phone to load a SIP load.

If you are "testing" a new SCCP load, don't like it, then revert the default firmware load to what you had before, when you perform a factory reset, it will load the newer SCCP firmware first, then load the default SCCP firmware, so basically doing the upgrade twice.

It all depends on the termXXdefault.xml or something like that.

I believe you can download/edit/upload them as required so you don't have to fool around with installing firmware files.

I'm sure others will correct me, but I'm pretty sure this is the dealio.

I’m doing a factory reset on a 7911 which has SCCP firmware 8.3(2) installed.  My CUCM has 9.0(3) as the default.

This should factory reset without issue, correct?
