No more voodoo...

voice class sip-profiles 100
 response 404 sip-header Reason add "Reason: Q.850;cause=21"

voice service voip
sip
sip-profiles 100

Seems to work. The "light" plan at bandwidth.com has Cuba blocked, and
what we normally get back from them is:

Received:
SIP/2.0 404 Invalid destination sip:+5378364072 at ot.bandwidth.com:5060

So by adding the cause=21 ("Call rejected") from

http://www.cisco.com/en/US/docs/ios/12_3/vvf_c/voice_troubleshooting/old/vts_appa.html

it falls through to our PRIs (without needing to change service
parameters on CUCM)
