That handles the IVR case, sure, but the harried, highly-caffeinated receptionist with a headset that can strike the "answer" button like a cobra remains a persistent challenge.
David -----Original Message----- From: VoiceOps [mailto:[email protected]] On Behalf Of Ryan Delgrosso Sent: Friday, June 13, 2014 09:41 To: [email protected] Subject: Re: [VoiceOps] Call established before audio path Ive seen this pretty regularly, often times it happens when there are multiple sip servers in the path, and the final 200ok with SDP takes a second to get to the endpoint. Especially when something that does symmetric latching is in the path. Its not uncommon for symmetric latching to cause this as the called audio will start flowing the moment it sends the 200ok, but the 200ok still has to be received by the caller and it has to begin sending audio for the latch to take and have the audio routed both ways. The answer is typically a 0.5 second delay at the start of your prompt to insulate against this.
