[cisco-voip] CUCM 8.6.2a SU2 and OpenSSH SFTP Server

[Ed Leatherman]

Eric,

I'm using openssh on Ubuntu for CUCM 8.6.2aSU2, UCCX 8.5(1)SU4, Unity
Connection 8.6something, CER 8. Also have some 9.x test systems pointed to
it. I've not run into any issues, I've been using it on that CUCM version
for about 8 months now. Nothing special configured on the server for any of
the backups to work.

3.1GB looks like its the biggest tarball i'm getting from CUCM for TFTP.
Connection message store backup gets up to 8.9GB.

Hope that helps or at least provides a data point for you.

Ed
