Cisco CUBE modification of response code?

[Clifford McGlamry]

Customer is asking if we can modify a SIP response code.  Specifically, when the CUBE receives a 487 (busy) response, the customer is asking us to return a 503 to the other leg.

Is there a way to do this?

Have a look at this url, it should have some information about what you ask about.

Interesting.  I'll have to lab this up.  Not sure if it will work as I'm trying to change the response code number itself, but it's worth a try.
