Hi Chris,
If I am understanding correctly, I think what you are looking to do is
possible. (of course - what isn't possible with determination and a big enough
hammer? ;) )
You can use the auto-answer capability of Group A's phones and the Page()
dialplan function. This would allow a Group B member to pick up the phone, and
end up broadcasting to all of Group A's phones. This should be the desired "B
Talks, A Listens" behaviour. (for one person in Group B, and multiple people
in Group A) The auto answer capability will depend on the make/model of the
phones.
Interesting things might happen if two different Group B people pick up their
phones at the same time - they would have no way of knowing they are stepping
on eachother, supplying a busy tone to the second Group B person who tries to
call should reduce congestion - if this is acceptable.
The second case of a Group A member calling a Group B member, such that
another Group A member can join into the call - I assume this is what some of
the web-based call managers do (haven't experimented with any of these, so I
can't say for sure).
Use Group A's speed dial buttons - one per Group B person. (* if you are
looking at Group B being across North America - you might run out of speed dial
buttons eventually)
Have the speed dial buttons connect to an extension in the dialplan that will:
- announce what conference number is about to be created
- connect the specified Group B person to the conference via a call file
created by a shell script
- then join the Group A person to the conference.
Your 2nd,3rd,etc. Group A participants would need to know (or guess) the
conference number and can join at will.
Alternately, Group A's phones might support some conferencing within the phone
itself.
The Asterisk mailing list may also have some good input on this. (I haven't
lurked there for a while)
I have the page() function working well with an installation of Snom phones,
and have experimented with call files. The only part I haven't worked with
directly is the AGI() dialplan command. On initial inspection - it doesn't
_SEEM_ too hard.
Curious - are you using the internet to connect your remote Group B's? I
would be interested to hear comments on the reliability and call quality. We
are just about to try a remote extension in Houston where the networking side
is handled by a WRT54GL with the openvpn version of DD-WRT installed, and the
phone is oblivious that it's operating through a VPN. (seems pretty solid with
my testing, now we put it in a user's hands.......)

Dana Harding

Subject: [clug-talk] asterisk wizard needed
Hi,
I'm hoping you guys can tell me if this is even possible in asterisk and if
it is possible who to talk to to hire as a consultant. I have two groups of
people group A (internal to my office) and group B (dispersed throughout North
America). Group A wants to hear everyone in group B coming out of the speaker
on their voip phone with the option of pressing a button and speaking directly
with a member of group B.
I think the easiest way to do this is to conference everyone and mute the
line in of Group A and mute line out on Group B (i.e have it so group B hears
nothing but can speak and group A hears everything but can't speak). Then, when
a member of group A wants to talk to a member of group B they can press a
button on their phone and asterisk will put that member of group A and group B
in a private conference call that any other member of group A can join. Is this
possible? Group B will be connected to the office where group A is by automatic
ringdown circuits (no dial tone, pick up the phone and you're connected).
Thanks,
Chris
