[asterisk-users] Unique call ID's across several systems

[Steve Edwards]

I have a farm of 7 1u's) with te410p's. When a call comes in, I call an 
AGI that creates a channel variable named GLOBALID. The GLOBALID is 2 
digits for the host number, 2 digits for the channel number, and 8 
characters for the UNIQUEID encoded in hex.

Then, I stuff it into CALLERID(name) so it will be available as the call 
is sent (using dial()) to the application servers.
