Thank you. May be a nice feature in the future to send an indication event when the call is answered.
The reason is if call A needs to be transferred to destination. When calling the destination B (originate the call). Some companies/departments play inband recordings instead of ringing. We have a customer who plays “Your call will be recorded for legal purposes”. Because call A needs to hear that message, we currently place both calls in a ConfBridge. Call A now hears the recording. 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) Currently, we require an agent to listen into the ConfBridge and decide when they believe it’s answered. Agent kicks everyone from the ConfBridge and the REFER (transfer) is sent. On some occasions the agent is incorrect or makes a mistake in doing this too soon, so the transfer fails. At that point, add everyone back into the ConfBridge, waiting for the agent to decide when to retry. Dan From: asterisk-users <asterisk-users-boun...@lists.digium.com> On Behalf Of Joshua C.

All is fine up to this point. It may take the caller several seconds before the called party answers. When the called party answers (200 OK received), in the debugging I see Asterisk processing this and debugging show TSX State: Terminated Inv State: EARLY At this point, the call is truly connected. Is there a configuration setting to indicate whether Asterisk should send an event indicating when the early media ends and the call is really Up? 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. -- Joshua C.
