<p class="MsoNormal">Thank you.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">May be a nice feature in the future to send an indication event when the call is answered.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The reason is if call A needs to be transferred to destination.<o:p></o:p></p>
<p class="MsoNormal">When calling the destination B (originate the call).<o:p></o:p></p>
<p class="MsoNormal">Some companies/departments play inband recordings instead of ringing. We have a customer who plays “Your call will be recorded for legal purposes”.<o:p></o:p></p>
<p class="MsoNormal">Because call A needs to hear that message, we currently place both calls in a ConfBridge. Call A now hears the recording.<o:p></o:p></p>
<p class="MsoNormal">If/when the call is really answered, we want to remove the calls from the ConfBridge and transfer A to B. (Successful transfer removes call from Asterisk and patches them internally in their switch NEC, Cisco, Avaya, etc)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Currently, we require an agent to listen into the ConfBridge and decide when they believe it’s answered.<o:p></o:p></p>
<p class="MsoNormal">Agent kicks everyone from the ConfBridge and the REFER (transfer) is sent.<o:p></o:p></p>
<p class="MsoNormal">On some occasions the agent is incorrect or makes a mistake in doing this too soon, so the transfer fails.<o:p></o:p></p>
<p class="MsoNormal">At that point, add everyone back into the ConfBridge, waiting for the agent to decide when to retry.<o:p></o:p></p>

<p class="MsoNormal">There is no option. The Originate code makes the channel appear as answered when the 183 arrives, everything reflects that afterwards. Even if a second answer occurs it gets ignored. The log message you refer to is internal state information
to do with the SIP side.<o:p></o:p></p>
