<p class="MsoNormal"><span style="font-size:10.0pt">Yes, we have a customer who used to work in a place with an old Panasonic PBX and Panasonic phones that had this feature and he loved it. His secretary could whisper in his handset, he’d hit a key and be able
to talk to the secretary really quick without the other party even knowing he’d done anything. We were told by a guy who used to consult for us on Asterisk stuff that this isn’t possible due to the nature of how SIP works, but we’ve always kind of wondered.<o:p></o:p></span></p>

<p class="MsoNormal">This would be pretty damn awesome, I've always been a fan of PTT and having this somehow mixed into your SIP handset would be cool.. having this hooked up to an external controller would be an awesome hack project. <o:p></o:p></p>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">You could even do it in software, a little desktop app for controlling your phone / open channel with a PTT button for intercom. <o:p></o:p></p>

<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Going back to your original question, the technical implementation, I'm not completely sure how this would be done. I'm wondering if you could use ESL to take over a channel temporarily.. perhaps you could place the call temporarily into
parking, connect the bridge to an application which records the audio, then pulls the call from parking and re-bridges.. perhaps using a remote initiated series of transfers. (there might be a more elegant way.. or maybe Anthony could write a small patch that
introduces this in a cleaner way).<o:p></o:p></p>

<p class="MsoNormal">That's actually a pretty neat feature, but I'm not sure how feasible it would be to do this via DTMF, purely on the user experience point of view.<o:p></o:p></p>

<div>
<p class="MsoNormal">For example, say your whisper key is *#, followed by the extension, then a final #, to start the whisper, so *#1234#, followed by another hash to stop the whisper - that's a lot of buttons to be pushing. And how would you handle the user
not currently being on a call? Would it record your response, call the extension, and play it back to them? <o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>

<div>
<p class="MsoNormal">In theory, something like this would be really cool, but without a dedicated PTT button on the phone I think it might be too fiddly to use - although this would really be personal preference and others may disagree.<o:p></o:p></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">For instance, the secretary whispers into the boss, “Hey, I have Mr. Jones on another call and he says it’s urgent. Do you want to take it?” and the boss wants to respond to the
secretary right there without putting the current caller on hold, so he hits *500 or something and tells the secretary, “Tell Mr. Jones I’ll call him back” without disrupting the current caller babbling on. Is this possible?<o:p></o:p></p>
