Try the variable sip_h_X-FreeTDM-ANI-TON Or just run the "info" app on the incoming call to show all variables. /Peter Från: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] För Nagalenoj H. Skickat: den 31 mars 2011 15:03 Till: FreeSWITCH Users Help Ämne: [Freeswitch-users] Knowing TON of each call Dear Friends, I'm using ftmod_sangom_isdn in my setup and I would want to know the TON(Type of Numbering) presented for each call. Is it possible to know the TON through channel variable in freeswitch?! Based on the Type Of Numbering of a call, I would want to modify the caller_id to a standard format and store in my database. It's always pleasure working with FS. Thanks. -- Nagalenoj H. !DSPAM:4d947c2432764944577751!
