Hi, We are trying to establish communication between a radio and a SIP user locally. Both radio and SIP phone are users of an asterisk exchange with no intervention of Allstar, Echolink etc. We have configured our system according to the link http://ohnosec.org/pipermail/app_rpt-users/2010-February/000788.html and now we are able to call from radio to the local SIP user. We are trying to do it in the reverse direction i.e. to enable a SIP user to call a radio. Can anyone please help us how can we configure this? Thanks and Regards Sarosh and Amber
