If you're looking to actually circumvent your proxy settings at will, that
will depend on what proxy/firewall/router your company actually uses, and
whether or not there are vulnerabilities associated with them.  You'll have to
supply more info on those items before anyone can say yes or no.  

However, if, as other replies have noted, you're just looking to get to one
particular server, there are other methods.  One which no one else has
mentioned however, is using Java or JavaScript through a browser with an HTTP
interface to telnet.  If you'd like to see an example, try this:

I cannot say what the degree of implementation difficulty is.  

HTH,
