Hi,
Consider a regular OpenSER + Asterisk solution: OpenSER is the
proxy/registrar, Asterisk hosts voicemail and conference, talks to
PSTN terminations, etc. NAT traversal is assisted by either rtpproxy
or mediaproxy.
In such a setup, can OpenSER be configured for barge-in? (If yes, how?)
Or, what do you think is the best way to approach this problem?
Thanks,
Sajith.

Hi!
What is "barge-in"?

According to https://studio.tellme.com/vxml2/ovw/bargein.html:
'In an automated telephone system, experienced users are accustomed to
interrupting the system to quickly navigate to the next prompt. In the
world of telephony this is known as "bargein."'
So, no, OpenSER can't do barge-in, since it's a signalling-only proxy.
It has to be supported by the voice application.

Well, sorry about not being clear. What I understood is more like this:
http://www.voip-info.org/wiki/index.php?page=PBX+Barge-In
"Barge-In is a feature in which an extension - such as an operator -
can break into a conversation between two extensions or an extension and
an outside line."

a signalling-only proxy.

Right. But signaling information is needed to start barge-in, right?
Once this is available, how to get a handle on the media?
What about some kind of SEMS hack? Or, is it possible to tap into
rtpproxy or mediaproxy for that matter? Assuming that some soldering
is required, of course...
Thanks,
Sajith.

If you send all calls to Asterisk you can use the features of Asterisk
for this.

True, but isn't it a little suboptimal? Say, I'm a supervisor in a
call center. I wouldn't want to barge into all calls, only certain
calls where my agents would need assistance.
Is there a way to initiate a directed call transfer sort of thing,
perhaps towards a conference room? Is 3PCC suited for such a scenario?
I'd imagine that proxy should need B2BUA functionality in this case.
And - thanks a lot for the responses. Much appreciated.

OpenSER is a proxy,
so for the requirement you have mentioned need a conference room
until you use Meetme or Appconference or any 3rd party
you can not have option to barge the call.

As per Klaus says 100 %. because OpenSER is powerfull sip signalling. its
cann't do media tracking the call, So if u pass all the calls to Asterisk,

Thanks for the suggestion.
It's pretty clear by now that openser can't do this out of the box.
I'm wondering if there's a way to stick this atop openser, say, using
duct tape and solder approach.

Sajith.
