[cisco-voip] Route patterns, translation patterns

Justin and Wes,

Thanks.  It's true that we are using CMI for SMDI integration, so we 
have some parameters
to play with.  Your problem will probably resurface when you begin to 
get international calls that want to go to voicemail. I think with a 
VG248 you can use dial peers to translate numbers in the SMDI messages.

Unfortunately, I cannot apply a single mask to the calling party number, 
it has to be different based on the source of the call.  If the call is 
generic PSTN, blank out the CPN, but if it is from an enterprise 
exchange, keep the CPN.  The legacy VM system, will look up a mailbox 
with the last 5 digits of any CPN, if there is a number there.  So we 
have to blank out CPN for non-enterprise exchanges or there are 
mismatches galore. (some algorithm, eh?)

I'm pretty sure I need to do this with variable translation patterns.  
These patterns have to be applied on a call that call forwards to voice 
mail through the device calling search space.  A direct dial to the VM 
access number doesn't require calling party number translation.  So what 
I'd really like is a flowchart that describes how a call routes when 
there is both a translation pattern and a route pattern.

thanks,
Candace
