I have a following observation:
After making 5 or so "transfer xxx XML default" in my dial-plan call brakes with [Exchange_Routing_Error].
This seems to be dependent on the number of extensions the call goes through, and not on the extensions content itself.

Could someone please confirm or deny such a behaviour?
If this is true would be nice to know where this"max number" can be increased/decrease.

P.S. I'm using "transfer" and multiple consequential extensions  as a workaround for "Variables Availability".
Thank you,
Victor
