Man, really, you don't know how things works so STOP saying that something is not what you need, only because you don't have the knowleage.

David, told you EXACTLY, what you need, send the API call to hold the B-Leg on the FreeSwitch.

YDSC ---- > FS ---- > PBX

If you send the HOLD api commando to FS, and told it to doit on the B-Leg of and outgoing call, FS will put the leg PBX on hold, EXACTLY as if you have a "hold"
button on your YDSC (Your Dumb SIP Client).
But as is more than clear, that you don't have a f**k idea how things works on the SIP world, you keep saying "that's not what I was asking for".

No, I was refering to the reply that still is not on the list, where I pointed you to and way to solve your issue using Asterisk, pointing you to the DOCS where it's explaixed how that AMI commands works and what you need to take into account on the dialplan to get it working.

That's point you to the docs WHERE it explained how it works. But you whant me to give you the full solution, that will not happen.

Again ... RTFM, I've told you more than tree times, that the solution is on the docs.

> Which ones, please?  You seem to know, why not just tell me?

Because I do not work for free, and your attitude on the thread, not ever reading the docs we point you, don't give me any incentive to do it so.

I could count at least 5 people on this list, that have told you, that could be done, but will be easier do it using a B2BUA.

Try to make me doing your job, and that will not happen, I've told you why.
I've point you to the docs where it's explained how to put a call on hold, in Asterisk throught the AMI and enabling some features on the dialplan manager.
I'm not going to give you a full step-by-step guide on how to do it.

I got it perfectly, It's just I don't want to give it to you, as simple as that.

Your answers show to me, and the rest of the list, that what you call "knowing Asterisk"
it's probably nothing deeper than runing an Issabel or FreePBX, if you would REALLY know Asterisk and the SIP protocol, you will not insist that what we have told you is not what you need.

Again an again ... YOU COULD DO THAT WITH A CUSTOMIZED B2BUA. Get it or leave it

So you say you know Asterisk and you don't know that on Asterisk and on any other SIP pbx, you could control the call flow using DTMF? ... Really?

http://www.asteriskdocs.org/en/3rd_Edition/asterisk-book-html-chunk/AdditionalConfig_id256654.html

Please read the [featuremap] section. You could do that control on the A-Leg or on the B-Leg, if your upstream PBX doesn't support DTMF call-control, THATS where your customized B2BUA take into place. If your still doesn't unsdestand that. Just give up on this.

> I'm looking for the textbook.  (Oh, and if your response is "buy the

And if you have it, why are you asking if Kamailio could do a B2BUA Role feature, like putting a call on hold? ... just because you don't undestand a word of what you have read from that book.

I'm been very polite on my replies, better you don't get see my BOFH side ;-)

There is thousands ways of skinning a cat, and you insist on the only one that don't work ... ;-)
