Hi,

I am using freeswitch server for android softphone development. When i am calling from my softphone to a mobile number, and if the receiver of the call hangs up without answering. then i am getting voice mail message from the receiver end. and The mobile number at the receiver end is receiving the call again.

please guide me which channel variable i must set in my sip providers dialplan, so that the call is established only once.

This behavior is not happening when i call between freeswitch extention to freeswitch extention.

Regards.
