Recently i noticed we have this strange issue: what we are doing is: first we create a conference for AGENT (because several party needed for the phone call) then we start dialing LEAD once LEAD answered the phone, I'll transfer this LEAD into AGENT's conference by using

uuid_transfer LEAD 'conference:AGENT' inline

if everything goes well, I'll receive this event very quick (usually less than one second)

Event-Subclass:conference::maintenance Action:add-member so i could get the LEAD's member_id (to do mute/deaf with member_id)

But, now, sometimes -- not always, we could not receive the conference::maintenance event with member_id after uuid_transfer command, it will take around 7 seconds to receive! I spend a lot of time on this issue, but still could not find any clue, and don't know how to reproduce it, but it still happens from time to time... I hope somebody could help me out. Thanks!! Eric
