I have partially solved the issue. In the dialplan I use a execute_on_ring to run: <action application="event" data="Event-Name=NOTIFY,uuid=${uuid},event-string=talk,content-type=application/simple-message-summary"/> This fires a notify to the phone called, which has nearly the right SIP to- and from-headers. Unfortunately the tag=xxxx in the to-header is missing. This tag should be the same as the tag in the SIP RINGING response from the phone, but somehow it is not passed on to the NOTIFY. The result is that the phone cannot determine which call should be answered, and it does not go off-hook. ________________________________ From: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] On Behalf Of Jon Bruel Sent: 18. juni 2012 15:39 To: freeswitch-users@lists.freeswitch.org Subject: [Freeswitch-users] sendevent NOTIFY After some time working with BroadSoft, I have returned to the FreeSWITCH, and I'm impressed with the overall improvements in consistency and documentation. Great work! I have tested the Event Socket sendevent NOTIFY command, and I have tried to check if I could change the SIP From and SIP To headers to suit my requirements. It looks as if there is no way. So is there a way to specify the From- and To-headers, including the associated tags? I need this to be able to control the phone sets (set it off-hook). Thanks /Jon
