Re: [Asterisk-java-users] Association channel-extension/context

[Bruno K. <bru...@un...>]

Hello Martin,
=20
thanks for your answer. I agree with you, * requires channel and context =
but the next question is "how to get that information if we
don't have it?". If the application making the originate does know only =
the extension is there a way to get the channel and context
associated to it. Using a command like "show dialplan" may work but I'd =
like to know if there is a better way.

thanks,

Hi Bruno,
=20
I took a look at =
http://www.voip-info.org/wiki/view/Asterisk+Manager+API+Action+Originate =
and
http://svn.digium.com/view/asterisk/tags/1.4.2/main/manager.c?rev=3D59053=

<http://svn.digium.com/view/asterisk/tags/1.4.2/main/manager.c?rev=3D5905=
3&view=3Dmarkup> &view=3Dmarkup and it appears that Asterisk
requires and immediately uses the context and channel.
=20
An extension can ONLY exist within a context, so that information should =
be readily available somewhere, if I'm not mistaken.
Without a context, I don't think Asterisk can uniquely identify the =
extension. As for a channel, your extension (for example a
softphone with SIP) will exist on a SIP channel. If you have the =
extension, you have the rest of these details -- without them, the
extension is indeterminate, I think.
=20
Each device has a channel. If you're doing out on a zap device, your =
channel is "Zap/n" where n is the channel number on the zap
device. If you're dialing a sip destination, you'll use "Sip/<extension =
#>".

Does that help?

Subject: [Asterisk-java-users] Association channel-extension/context


Hello all,

I would like to make an OriginateAction with knowing only the extension =
which will make the call (the calling extension) and
extension which will be called. I don't know the channel neither the =
context of the calling extension. Yet I would like to know if
it is possible to get that association from a manager action or command =
(I mean the association of an extension with the channel and
context to initiate calls).=20
For example, "show dialplan" may give information (it forces to parse =
the dialplan and I imagine it may be tricky if macros or
variables are used) but I would like to know if there is a better way to =
do this.=20

Thanks for your help,
