[Asterisk-Users] Nested/cascading "switch" statements: possible?

[John Todd]

I'm lazy and decided that I didn't have the time to hack up a few 
servers for testing, which I'll probably have to do if nobody answers 
this mail, but it's late in this part of the world and I'm tired.  :-)

I'm wondering if the use of the "switch" statement can be nested, 
such that system A has a "switch" statement that points dialplan 
inclusion to server B, and server B has in that context a "switch" 
statement which points to server C.  Therefore, server A knows about 
extensions on server C only indirectly, through server B, though the 
media path of course may actually end up going directly A->C (if it's 
IAX or SIP.)

Google, the Wiki, nor my mail archives had anything that obviously 
matched my search keywords, though I can swear I've seen this 
question on the list before.  It sounds too good to be true, and I 
know what that means...
