Trying to SSH to 79XX phones

[Clifford McGlamry]

Trying to SSH into some 79XX phones on clusters running CUCM 10.5 and 11.  It's not working.  I set the SSH username and password, and enabled SSH.  I get the intial connection dialog, but never get the login before it disconnects.  I've put wireshark on it, and while I'm not seeing anything obvious, I'm thinking it might be related to the encryption capabilities of the older phones.  

Has anyone else gotten this to work recently?  If so, what am I missing here?

use Putty for ssh & see what's happens..
also test other ssh encryption protocol with it..

Figured this out.  I had to go download a much older version of Putty, and it was able to connect.  Using wireshark, I was able to see that the phone and the SSH client weren't able to agree on an encryption protocol, so the handshake was failing.  Older version of putty worked just fine.  Unfortunately, it didn't help me.  No ability to do a reset to factory defaults or change phone configuration on the 7900 series via SSH that I could find.
