I have not done a deployment in the last year, but before that I've done 
multiple installation with the 3300 and ever ran into this issue.

Is this on the same LAN, I assume there is no routing issue?

A SIP debug log from Asterisk would be helpful.

But to answer your question, there is no way to change SIP response 
codes via the dialplan, you would have to modify the source for 
chan_sip.c (something I do not recommend).
