i am working on DISA in Freepbx and able to make call back service in which if i call to my pbx it will disconnect my call and call me back then it will convert my call to DISA and after giving password i can make call to any destination mean in this i am paying call charge for only my PBX and my issue is that if i am calling from my mobile, after call back when i am in DISA it is giving me dial tune but i am not able to make any call from my mobile because of dial tune do you know how to use DISA from mobile access.
actually when i m calling to my pbx from my number i am able to enter in DISA but not able to press any key because when i m pressing any key its nothing happens and i am online able to lessen to dial tune because i remove the DISA password, one more thing i am using only one SIP for callling and transfring the call.
I am using this setting in trunk for DISA
