Hi Steve, Thanks for interest. Yes, i figured out that i cannot eavesdrop any 'easy' way. I tried the approach you described (dialing into FS2 to a special context and passing sip-h_X header). In fact i use this to bridge calls on different FSes. But while i managed to get it working with bridging, i cannot find a way to do eavesdropping. With bridging I send: uuid_transfer [CallA channel] bridge:{sip_h_X-target_channel_id=[CallB channel]}sofia/bridging/123456@ip:port,park inline Then FS2 in dialplan for 123456 extracts target channel id from sip header and intercepts it: <condition field="destination_number" expression="^(123456)$"> <action application="intercept" data="${sip_h_X-target_channel_id}" /> </condition> What actions should i define in FS2 dialplan for eavesdropping? What inline dialplan should i send in dial string? I'm stuck here. -- View this message in context: http://freeswitch-users.2379917.n2.nabble.com/Eavesdrop-between-2-FS-instace...
