[cisco-voip] Expressway Search Rules - Source:Any -or- Source-Named Zone

[Lelio Fulgenzi]

Curious - what are people doing with their search rules? I've got a search rule for calls coming from the 'net into E and then to C all good, but just wondering, I know the search rule on E has to be source:ANY because it's coming from the net, but what about the search rule on C? Shouldn't it be source:named zone (and pick C-to-E traversal zone) to be sure that nothing else hits it?

Same goes for say rules that I use to send calls all the way from CUCM to C to E to DNS Zone. Shouldn't my rules be as specifically configured as possible? Including the source zone?

I understand that if I start registering devices on either the C or E I will need to create additional rules, but I'm fine with that, that way I know exactly what's going to hit.

What are others doing? What's the best practice?
