I have successfully originated calls and dumped them into my Stasis app. I am trying to figure out what the best way is to send a channel into an Application. The current architecture for /channels/{id}/play works well for the majority of my app, but I am running into a block figuring out how to interact with Asterisk dialplan applications.</span></div><div><span style="font-size: 14px;"><br></span></div><div><span style="font-size: 14px;">To give an example - I submit an originate to go to SIP/vendor/phoneNumber - with the other leg going to App: myStasisApp, {"soundFile":"blah"}. That works fine (with the proper quote escaping). Now my Stasis app has received the channelID to which we can do a lot of neat stuff. Say I play a sound to the user but then want to call the app WaitForSilence. What's the best way to do this? I may be misinterpreting the intended use of both Stasis and ARI - but I am curious to see what your thoughts are.</span></div><div><span style="font-size: 14px;"><br></span></div><div><span style="font-size: 14px;">Also, for the stasis app to get a list of arguments, I am passing it through as JSON. So far that is working fine - but I wanted to see if there was a better way to get a list/array of app args to Stasis.</span></div><div><span style="font-size: 14px;"><br></span></div><div><span style="font-size: 14px;">Forgive me if there is an easy solution - through digging and poking the last few days, I have not been able to find the intended use case or even a use case.</span></div><div><span style="font-size: 14px;"><br></span></div><br></div></blockquote></div><br></div></div></div><div style="font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;">Well, the solution for this just got added into the Asterisk 12 branch, and so it hasn't made it into a release yet.

This lets you asynchronously 'know' when both talking/silence has occurred - obviating the need for the WaitForSilence/WaitForNoise dialplan applications. Plus, because it is asynchronous, if you decide you don't *want* to wait for silence, you don't have to!<br><br></div><div style="font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;">With a bit of manipulation, you could also construct AMD from this as well - but I'll admit that's a bit more challenging. I'd be interested in people's experiences with attempting to do that, and if an asynchronous "IS_HUMAN" detection function is needed or not.<br></div></div></blockquote><div><br></div><div>We are in the process right now of creating an application that needs asynchronous AMD.

Is the reasoning behind doing this instead of starting the call with WaitForSilence or AMD because you want the user to not have a delay when they answer the phone and when the message is played? We've found through testing Lumenvox's CPA and Sangoma's, that the super simple WaitForSilence works _pretty_ well (especially with some threshold "tweaks"), but our use case is just the guarantee of message delivery, not a possible agent/queue scenario. Regardless of what our use case scenario is vs yours, I can definitely see a problem with asynchronous use. Let me know what you find!</span></div><div><br></div><div>I could imagine if you could get the stats from the CPA in real-time to change the path of the call, that would be really neat but impossible right now.

While Adhearsion sees both the input and output components as being asynchronous, this is a fake facility provided by Punchblock to make Asterisk look like an async server when it is not.

It cannot be honoured for the async case, nor can any equivalent alternative be introduced, without changes to Asterisk.</p></div></div><div><br></div><div>[1]: <a href="http://www.lumenvox.com/products/speech_engine/cpa.aspx">http://www.lumenvox.com/products/speech_engine/cpa.aspx</a></div><div><br></div><div>/BAK/</div><div><br></div><div><div><div style="orphans: 2; text-align: -webkit-auto; widows: 2; word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;"><span style="border-collapse: separate; border-spacing: 0px;"><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;"><span style="border-collapse: separate; text-align: -webkit-auto; border-spacing: 0px;"><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;"><span style="border-collapse: separate; text-align: -webkit-auto; border-spacing: 0px;"><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;"><span style="border-collapse: separate; border-spacing: 0px;"><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;"><div><div>-- </div><div>Ben Klang</div><div>Principal/Technology Strategist, Mojo Lingo</div><div><a href="mailto:bklang@mojolingo.com">bklang@mojolingo.com</a></div><div>+1.404.475.4841</div><div><br></div><div>Mojo Lingo -- <i>Voice applications that work like magic</i></div><div><a href="http://mojolingo.com/">http://mojolingo.com</a></div></div><div>Twitter: @MojoLingo</div><div><br></div></div></span></div></span></div></span></div></span></div></div></div><br><blockquote type="cite"><div><div style="font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;"><br>[1]<span> </span><a href="https://wiki.asterisk.org/wiki/display/AST/Asterisk+12+Function_TALK_DETECT" target="_blank">https://wiki.asterisk.org/wiki/display/AST/Asterisk+12+Function_TALK_DETECT</a><br>[2]<span> </span><a href="https://wiki.asterisk.org/wiki/display/AST/Asterisk+12+ManagerEvent_ChannelTalkingStart" target="_blank">https://wiki.asterisk.org/wiki/display/AST/Asterisk+12+ManagerEvent_ChannelTalkingStart</a><br>[3]<span> </span><a href="https://wiki.asterisk.org/wiki/display/AST/Asterisk+12+ManagerEvent_ChannelTalkingStop" target="_blank">https://wiki.asterisk.org/wiki/display/AST/Asterisk+12+ManagerEvent_ChannelTalkingStop</a><br>[4]<a href="https://wiki.asterisk.org/wiki/display/AST/Asterisk+12+REST+Data+Models#Asterisk12RESTDataModels-ChannelTalkingStarted" target="_blank">https://wiki.asterisk.org/wiki/display/AST/Asterisk+12+REST+Data+Models#Asterisk12RESTDataModels-ChannelTalkingStarted</a><br>[5]<a href="https://wiki.asterisk.org/wiki/display/AST/Asterisk+12+REST+Data+Models#Asterisk12RESTDataModels-ChannelTalkingFinished" target="_blank">https://wiki.asterisk.org/wiki/display/AST/Asterisk+12+REST+Data+Models#Asterisk12RESTDataModels-ChannelTalkingFinished</a><br><br></div><div style="font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;">Matt<span><font color="#888888"><br><br></font></span></div><span style="font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;"><font color="#888888">-- </font></span></div></blockquote></div><br></div><div><div>_______________________________________________</div><div>asterisk-app-dev mailing list</div><div><a href="mailto:asterisk-app-dev@lists.digium.com">asterisk-app-dev@lists.digium.com</a></div><div><a href="http://lists.digium.com/cgi-bin/mailman/listinfo/asterisk-app-dev">http://lists.digium.com/cgi-bin/mailman/listinfo/asterisk-app-dev</a></div></div></div></span>
