Hi, I am trying to achieve 3-way conferencing taking hint from wiki link http://www.voip-info.org/wiki/view/Asterisk+n-way+call+HOWTO
Here is the scenario: 1. user "ua1" calls user "ca1" 2. "ua1" then presses the feature code "*0" to redirect "ca1" to conference room 300 3. "ua1" then dials the user "33" 4. user "ua1" and "33" are connected 5. Now when "ua1" presses the feature code "**" to redirect user "33" to same conference room 300, there is error thrown on Asterisk console that "res_features.c:1415 ast_bridge_call: Bridge failed on channels SIP/ua1-ac750040 and AsyncGoto/Local/[EMAIL PROTECTED],1<ZOMBIE>" Here is my dial plan: [manu] exten => ca1,1,Dial(SIP/ca1,,wWtTkKrR) [nway-conf] exten => _.,1,Answer exten =>
