Hello Anthony,
As discussed earlier, Kamailio is not the right tool for your specific requirements. Here
on this list are people naturally most experienced with this software.
We can also not provide a detailed solution to any problem.
Regarding about telling the PBX to put the call on hold, one way how to do it is by
sending a Re-INVITE with a changed SDP from one of the called parties.
Maybe you can get more detailed and useful answers for you at the Asterisk or Freeswitch
user lists.
If hiring somebody is an option for you, we've is a business list available where you
can just ask for people to contact you regarding your particular requirements. You will
find similar lists also for other projects.
Best regards,
Henning

So, if your are unable to follow a hint, read the docs,
Which ones, please? You seem to know, why not just tell me?
Try what? I'm just saying that if you know how it can be done, please show me an
example.

David told you how to do it with FS,
No, he told me how to get FS to put a call *which it is processing* on hold *inside
FreeSwitch* - that is *not* what I need to do - I need to send a command to the *existing
PBX* which is handling the call so that *it* puts it on hold, just the same as it would if
I had standard SIP phone and could press the "hold" button.
2) Put a
B2BUA in front of that SIP Endpoint, and throught API,
DTMF, RPC or witchever method that B2BUA gives you, you will have
to emulate what your SIP Endpoint doesn't support
Precisely what I am asking how to do, thank you. I told you, how to do it with Asterisk, (if you wait a
couple of
hours, message will be approved and posted on the list)
If you are referring to:
"The thing you need it's a B2BUA, and Asterisk, FreeSwitch, YATE, SEMS, either a
simple python script using pjsua2 or any of the dozens SIP frameworks out there, will
allow you to acomplish your goals
"If you go the Asterisk road, any of the AMI/ARI documentation will explain to you
how to handle ongoing calls."
then this neither tells me how to do it, nor is it even what I need to do (see above about
FreeSwitch).
We give you hints about your options to solve your
issue. And there is
much more ways of solving the issue.
Please show me just one of them.
You have been given with the hints about how to solve
your
problem,
Hints are all very well, but telling me "put a B2BUA in front of
that SIP Endpoint, and use API, DTMF, RPC or witchever method that
B2BUA gives you" doesn't exactly help when I've made it perfectly
clear that I don't know how to solve the problem. try the things on your own and ask the right questions
on the right
place, better you hire someone that could solve it for you.
If I find someone who says they can do it, that's definitely an option.
If it really
is that simple, please just point me at one example of
how to actually do it.
Good try. It's really simple, for someone that knows how
things works. With a
minimal of dialplan programing knowleade of Asterisk, FreeSwitch, YATE, SEMS, etc.
and how to interact with that B2BUA from outside the SIP channel.
You really don't get what it is I need to do.
I do NOT need to build myself a B2BUA using any of the above tools and get *that machine*
to put calls on hold, transfer them, conference, etc. I can, and have, done that
perfectly well using Asterisk. Despite your opinion, I do in fact know both SIP and
Asterisk pretty well.
What I need is something which can tell *the existing server* to put the call on hold,
resume it, or transfer it, in just the same way that a competent SIP telephone can tell
the server to do that.
On the other email I pointed you how you could solve
it with Asterisk,
using CDF+AMI PlayDTMF command
How does playing a DTMF tone down a channel tell some other server to put a call on hold?
That makes no sense at all.
Giving you a hint, doesn't mean solving you the
problem. Means, you
must do you homework.
I'm looking for the textbook. (Oh, and if your response is "buy the Kamailio
book", I have.)
I have tried to be polite in my responses to you; I would appreciate if you
did the same.
Regards,
Antony.
