hello every one, i have an asterisk system and want to act as gateway and send calls to cisco gatekeeper. this is my h323.conf file: [general] port=1720 binaddr=192.168.0.YY context=from-trunk faststart=yes h245tunneling=yes gatekeeper=192.168.0.XX //cisco address progress_setup=8 progress_alert=8 dtmfmode=rfc2833 jbenable=yes jbforce=no jbmaxsize=200 jbresyncthreshold=1000 jbimpl=fixed jblog=no and this is extension that i defined for it in extensions.conf: exten=>_2.,1,Dial(H323/2${EXTEN:1}) (if i define my extension like (exten=>_2.,1,Dial(H323/to-cisco/2${EXTEN:1}), asterisk returns core dump error. but, i can't send my calls to cisco gatekeeper. do you have any suggestion what is wrong with my configuration? thanks in advance SAM -------------- next part -------------- An HTML attachment was scrubbed...
