[Asterisk-Users] Redirect two channels to each other?

I've been scratching my head trying to think of a way to do this, but
without success yet.

I'm using the Manager API. If I have two channels linked to each other
(i.e. direct connection), or even if they are independent channels,
I can transfer them both to the same extension by using Action: Redirect
and using Channel: for one and ExtraChannel: for the other. This is most
useful for putting them both in the same Meetme conference.

What I want to do is find a way to take two unrelated existing channels
(which for the sake of argument might be sitting in MusicOnHold, separate
conferences, the same conference or whatever), and link them together
into a direct call rather than having them talk via their own Meetme
conference.

Does anyone have any ideas if this can be done?

Cheers
Tony

I have no ideas, other than Meetme. It sounds like it would involve some 
direct modification of the * code. Its similar to the pickup code - perhaps 
start there. Let me know if you find anything - id be intersted in a solution 
for it as well, i just dont have the time to find a solution.

[Asterisk-Users] Redirect two channels to each other?

As ny 10 year old step-daugher says "I don't get it.."

Can't you just do a redirect if you specify the channels, * doesn't care
if they are bridged together or not.  You may end up with zombie
channels if the other leg does not drop, but you could do a soft hangup
and take care of that..


Or am I missing something????

[Asterisk-Users] Redirect two channels to each other?

Maybe this would best be explained in a diagram:

1).  person A <---> music on hold      and      person B <---> music
on hold

2).  *some manager API action*

3).  person A <---> person B


This is what I think he's asking about, how do you take two parties on
different conversations and put them together without using a meetme
conference?

[Asterisk-Users] Re: Redirect two channels to each other?

I haven't looked through the code yet, but no, there is no easy way that
I've discovered to be able to do this, although it seems like there should
be. 

All that we really need to be able to do is somehow execute a 'Link'
action
between two channels that would bridge the two desired channels and unlink
whatever those two channels were originally connected to. I'll take a look
at the manager API code later this week and see if there's any easy way of
patching it to accomplish this.

Thanks,

MATT---

Thanks Matt, that is exactly what I am asking. I assume you haven't found
a way either, otherwise you would have mentioned it! :-)

[Asterisk-Users] Redirect two channels to each other?

I would suggest opening up a bug on the tracker, if it hasn't been done
already, for all of these discussions to be logged to.
>From my glancing at the code, I think there would be a little more cleanupinvolved in it than just the ast_bridge_chan function. But either way being
part of the Manager this is going to have to be clean enough to pass the
Mark test to make it into CVS. Any master Asterisk developers listening out
there who would like to tackle this one?

Fine by me...but does anybody know the relevant subs in any of the asterisk 
source that actually does the bridging? I mean, is it possible that its as 
easy as: 'void ast_bridge_chan( ast_chan * a, ast_chan *b )' and we just
need 
to package it as a manager action? Anybody have any pointers on how to 
proceed?

[Asterisk-Users] Redirect two channels to each other?

This may be somewhat of a cross-post with -dev, but I have Manager Bridge
Action working under CVS_HEAD and releases 1.0.6-7.

I dunno...maybe _im_ missing something..

IIRC (http://www.voip-info.org/wiki-Asterisk+Manager+API+Action+Redirect), 
Manager action 'Redirect' only takes Channel, ExtraChannel, Exten,
Context,
and Priority as parameters.  

Example (transferring existing 2 party call to a meetme room): 

Action: Redirect 
Channel: Zap/73-1 
ExtraChannel: SIP/199testphone-1f3c 
Exten: 8600029 
Context: default 
Priority: 1 

The problem is that you cant redirect to an existing _channel_.  I dont know

of any channel 'hack' like there is for Local extensions (e.g. to make
an
extension look like a channel, use Local/1234@context, etc - is there the 
inverse of that? Make a channel look like an extension?) 

It almost sounds like there needs to me a new manager action:

Action: Bridge
ChannelA: SIP/199testfone-1f3c
ChannelB: Zap/6-1

It sounds like the intrinsic functionality for 'bridging' is already
there
in 
Asterisk (duh!), it just needs to be encapsulated in a manager action.

Any takers? Maybe a bounty is needed...?
