I have some phones with the version of firmware 220.127.116.11,
I try to upgrade to 18.104.22.168, but I always do that and I get these error, and the device is locked for a long time for "unregistered"
These phones get locked for about 40 minutes, and some of the DO upgrade, and some do not and return with firmware 22.214.171.124
Like this phone: (The status message of this phone was the above)
And now is registered.
This is what I have in the Device Defaults.
(on a different device pool)
also, y' my phone take the 126.96.36.199 firmware if I told to the call manager not to do so on that device pool (lag) and just "Qrocampus" take changes. :S
There are the file names I have on my TFTP server (and subscribers also), for that model.
Please, helpme, what em I doing wrong?
Well, This scenario was solved this way.
The problem as that many phomes had differents levels of firmware's versions, and the leased lines T1 has too low bandwidh for the burst of UDP pakets the phones need to download.
1.- On every server cluster we installed all the versiones of firmware SCCP from 8.5.1 to 9.2.1.
2.- By bulk administration on the "phone load name" parameter, we upgrated those who had the oldest firmware to "normalize them all".
3.- We did this on the late night so our leased lines could handle all the TFTP request from the phones.
4.- We did this per brach office... one by one.
5.- That's it!
5 Stars for me
