We have 2 Freeswitches with a Sangoma A200 connected with an crossed E1 cable. Wanrouter is version 3.5.24, Freeswitch version is FreeSWITCH Version 1.0.head (git-3004fa0 2012-02-15 16-24-21 -0600). If I originate a call from one freeswitch to the other, I can see that the TON (type of number) for called and calling party is set. ...

But in the caller profile variables, the variable "variable_caller_ton" is not set. On our production system, connnected to the real PSTN, this variable is always set (also with the same freeswitch version). What could be the reason why "variable_caller_ton" is not set? Thanks Markus
