Kermit and FTP are two different protocols. FTP is the standard Internet
file transfer protocols, but, as many people are learning, it can not (in
general) be used through firewalls, and it is difficult to automate.
When you say your client's host does not accommodate Telnet sessions, this
probably means that they have elected not to run a Telnet server. Thus
users can not use a Kermit program such as C-Kermit, Kermit 95, or MS-DOS
Kermit to make a Telnet connection to this system and transfer files over
that connection, at least not in the normal fashion.
But there are other approaches, depending on the platform. If the host is
UNIX-based (for example), the Kermit program for UNIX, which is C-Kermit
6.0:
http://www.columbia.edu/kermit/ck60.html
can be set up accept incoming TCP connections on the socket of your
choice, just like an FTP server, except using Kermit protocol rather than
FTP. This is documented in the manual, "Using C-Kermit", 2nd Edition,
pages 127-128.
