I'm trying to configure a 2901 CUCME router. It has IOS 15.1(1)T and CUCME 8.0.
I am having a problem with 7941G IP phones downloading their firmware. I have tried various versions of the firmware and watched it download via debugs:
*Jun 4 21:03:10.247: TFTP: Server request for port 49152, socket_id 0x29D24A78
for process 87
*Jun 4 21:03:10.247: TFTP: read request from host 192.168.150.51(49152) via Gig
*Jun 4 21:03:10.247: TFTP: Looking for term41.default.loads
*Jun 4 21:03:10.247: TFTP: Opened flash0:term41.default.loads, fd 15, size 642
for process 87
This is where it stops and the phone reboots to the Cisco splash screen with a target symbol in the lower left. I only have 7941G phones to test with but this is happening with mulitple phones.
I have the option 150 set in DHCP and the proper tftp statements (with the files uploaded to flash):
I've also upgrade the IOS from the factory installed 15.1(1)M2 and the problem was there for both IOS images.
Any help would be much appreciated!
Solved! Go to Solution.
I thought that the firmware was self contained and you didn't have to step through anything?
I'll give it a try though.
I'll let you know...
Why? Two IOS changes and four different phone firmwares to find the right combo?
Is that normal?
I haven't done millions of these but enough to think this is wacky.
Thanks for the help Rob! Post rated.
This is not a usual requirement for phone firmware and
has really messed things up for many, many people and upgrades/
installs. It has been many years since there was a pre-requisite firmware
requirement for any version. I'm not sure what happened with the newest
versions or why they require this "mid-point" step. But at least you have
moved past this and on to bigger better things It's a royal pain that will
bite many more people in the foreseeable future.
Yes, this is a real pain in the you know what
Firmware Upgrade Issues for SCCP
Note For all SCCP firmware upgrades from firmware release versions earlier than 8.3(3) to version 8.5(2)SR1 or greater, you must first upgrade your firmware to version 8.5(2). Once you have upgraded to version 8.5(2), you can upgrade your IP Phone to version 8.5(2)SR1 or later.
Hope this helps!
Hello, we experienced the same problem when upgrading to CUCM 7.0 and also with 8.0 on the phones that weren't plugged in to see version 7.0.
Had a case yesterday with an older 7911G, I did the manual to 8.5.2 and then after that let it go to SCCP41.9-0-2SR1S by itself.
Tonight we upgrade to the latest brand-spankin new 8.0.2c!
