As the previous posts show there are 2 ways that you can specify the address to be used for telnet from an IOS device. If you want that the telenet source address will always be the specified address then you should use the configuration option of:

ip telnet source-interface

and if you want that the telnet source address be controlled only for this telnet then you should use the command line option of:

telnet 10.1.1.1 /source-interface loopback 0

So the way to do it depends on whether you want a permanent change or control just for a particular telnet session.
