[Freeswitch-users] Svar: Re: Somebody help me understand the 'features' set up please :-)

[mailinglist]

Hi Michael
 
I'm trying to get the possibility of transfering an incoming call from one extension to another, and give the possibility of turning it into a conference.
I don't have a 'transfer' button.
I do have an 'R' button on the Siemens handsets, and a 'Flash' button on the Sipura. The 'Flash' button gives me a new dialtone, gives the caller MOH, and then I can dial the new extension, and transfer the call, but not create a conference.
But the Siemens handset does not have a 'flash', and pressing the R doesn't do anything.
 
It might be two different features 'transfer' and 'conference'...

But I thought that using the bind_meta_app would accomplish both.
 
It's on an incoming call from the outside.
So the situation:
The Public folder has an entry that matches the dialed number, and does a transfer to 8202.
Then the dialplan matches the 8202 with a group, and the phone rings.
Somebody picks it up, finds out that it needs to be transferred to another extension, or transferred to a conference with a second extension.
 
 
Best regards
Fribse

Hmm, I've just downloaded the default.xml under conf/dialplan from the SVN just to be on the safe side.
Line 758 is the last </include>, but I did find some examples on line 249-251.
So I've changed my dialplan entry handling calls from the outside to this:

<extension name="PrivateIn">
<condition field="destination_number" expression="^(8202)$">
<action application="bind_meta_app" data="1 b s execute_extension::att_xfer XML features"/>
<action application="bind_meta_app" data="2 b s record_session::$${recordings_dir}/${caller_id_number}.${strftime(%Y-%m-%d-%H-%M-%S)}.wav"/>
<action application="set" data="call_timeout=45"/>
<action application="set" data="domain_name=10.11.12.25"/>
<action application="set" data="continue_on_fail=true"/>
<action application="set" data="hangup_after_bridge=true"/>
<action application="set" data="transfer_ringback=$${hold_music}"/>
<action application="bridge" data="group/private@${domain_name}"/ ( mailto:group/private@$%7Bdomain_name%7D%22/ )>
<action application="answer" data=""/>
<action application="sleep" data="1000"/>
<action application="voicemail" data="default 10.11.12.25 45"/>
</condition>
</extension>
As I understand the bind_meta_app it listens for *1 and then it runs the att_xfer, *2 to record the call.
I've included the att_xfer in the XML features.
Question is, will it work at all when I bridge to a group?
Nothing happens when I press *1 and an extension.


Fribse,

I think your confusion might be from the purpose of the bind_meta_app application. The *1 or *2, etc. must be dialed after the call has been established. In other words, bind_meta_app sits there on an existing call, listening for *1 or *2 (etc.) and if the person on the appropriate call leg dials it then the application in bind_meta_app gets executed. Example:

<action application="bind_meta_app" data="2 b s record_session::$${recordings_
dir}/${caller_id_number}.${strftime(%Y-%m-%d-%H-%M-%S)}.wav"/>

The "2 b s" part of that means: Listen for *2 on the b leg and execute the app on the s leg. So, the b leg could dial *2 and it would initiate call recording. 

Let's take a step back... are you sure you need bind_meta_app? What exactly is your use case here? In general terms, what are you trying to accomplish with your dialplan extension?
