Found some new firmware was released on Dec 10th for the 7970 series of phones. This brings it up to 8.2 instead of the 8.0 series. Lets hope it fixes the MWI issues we’re all experiencing.

I haven’t finished my full testing of this firmware yet, however it does seem to boot on the phone.

I also noticed that in order to perform the upgrade, and if your tftpd server is running on linux, you will have to rename a file to a different case to get the phone to recognize it, and load it.

Do this for it to work..

tftproot 
# mv jar70sip.8-2-0-55.sbn Jar70sip.8-2-0-55.sbn

Now the phone will take it during the upgrade. Stay tuned for more 7970 action soon!
