I was wondering if anyone could help me out with a problem we have been having with one of our handsets.
We have a UC500 with a number of 7961 handsets connected to it, and then three remote locations with SR520's with a smaller number of handsets (and ATA adaptors we are trying to use for fax) connected. The main site were the UC500 is located has been up and running without a hitch, as are most of the remote sites. The phones at one of the remote sites were acting strange however, and I fear our response create another problem.
The ATA adaptor at the site was registering fine, but both phones lost their registration and wouldn't re-register to the UC500 (though the VPN tunnel remains up and un-affected). On one of the handsets, I followed the procedure given by Cisco to reset the phone to factory default configuration (reboot, hold down # until the line buttons start flashing, type in 123456789*0#, etc). The phone rebooted, and then tried to go through the upgrade process, but it kept throwing an error, and then rebooting and trying to upgrade and throwing up and error message, and rebooting... etc. It seems to be stuck in a loop. This was true at the remote site, or if it was plugged directly into the UC500 at the main site.
The other phone at that site, I simply went into the menu (after the first phone was displaying this odd behavior), and had the handset reset it's network configuration, after which it found re-discovered the 10.1.1.1 as it's TFTP address (which it hadn't been doing before), and is now fully functional.
Does anyone have any ideas on how I might reclaim my rogue 7961 handset?
On a slightly related note, does anyone know how to disable the second port on an ATA 186? The ATA 186 is registering fine, but it is registering both analog ports as independant extensions (and using up seat licenses) where we only need one port on each adaptor. Any idea you had would be greatly appreciated.
Thank you for your time.
