[Asterisk-Users] RE: IAX Passing Variables

Well, this kinda sux.

We have three Asterisk servers. Phones register to a single, 
primary server.
When a phone on one wants to reach a phone on another, we use 
DUNDi to discover the destination pbx and IAX to transfer the 
call to the other Asterisk box. This seems to be a fairly 
common practice amongst Asterisk users, yes?

Well, what about setting variables before call placement? Say 
you want to set the variable _ALERT_INFO, to have Polycom 
phones auto answer? Essentially the problem is that channel 
variables (with the exception of caller id) are not passed 
from one Asterisk box to another with IAX. How have people 
gotten around this?

Doug.
