Older version of sftp

The newer version of SW Sftp uses stronger hashing than our Cisco Voice servers and therefore we aren`t able to do backups, I`m looking for an older version of SW sftp to get me by until we upgrade our voice systems.

  • What version of SFTP are you using? How do you tell what hashing the SFTP server is using?

    I recently upgraded Call Manager to 11.5(SU8) and I can no longer install software (COP files) from the SFTP server, however the backups going to the SFTP server are still working.  The 11.5(SU8) upgrade removes the diffie-hellman-group14-sha1 algorithm due to a vulnerability.
