Sorry for the double post ... actually hit send too early ...

OK ... Here goes another I'm doing this with AST ... but I want to move it to FS. Searched via google site:lists.freeswitch.org auto dialer and others ... nothing useful.

Today I have a platform for auto dialing with AST (centrally managed ... about 10 machines) and we do this:
-- Remote machines query central DB for numbers to call based on certain configs
-- Use AMI to generate the call
-- If call gets answered, extension info queried via rta (central db again)


The nice thing about all of this is it's relatively easy to manage (through one central web interface we built) and it works ... the bad part is reporting ...

So ... conceptually I'm trying to accomplish the same thing ...


Today we use FS a lot for termination of VoIP traffic ... all done via XML_CURL ... which is awesome (not to xml cdr ... and the "proxying" of media) ...


Would like to do something like:
-- originate request (looks simple enough)
-- on answer XML_CURL posts info

But for the life of me I can't figure out how to translate this into the xml response ...

[campaign]
exten => 100,1,ANSWER()
exten => 100,n,WAIT(2)
exten => 100,n,BACKGROUND(${SOUND_DIR}/somefile)
exten => 100,n,WAITEXTEN(10)
exten => 100,n,HANGUP()

exten => 1,1,PLAYBACK(goodbye)
.... and so on ...

I've looked at the ivr.conf stuff but it's all static and all of this has to be manageable via a web interface .... meaning dumping into a DB and returning an XML response seems reasonable ... but trying to stick or modify static text files from the web interface is too much text parsing and bad things will happen ...

Any thoughts or pointing me in the right direction would be appreciated.

Does AST mean Asterisk Open Source PBX ?

If so, then yes I am familiar with it's archetechure as I am a former developer from that project.

You have 3 choices with FreeSWITCH

1) You can open a dedicated connection to mod_event_socket or XMLRPC per call and issue the originate command from there:
This will block until you know for sure the outcome of the attempt. If it's success it will give you the uuid if not it gives you the cause code.

2) You can use a single mod_event_socket or XMLRPC connection to send all calls but use the bgapi mechanism which will do the same as above
only asynchronously, The command will return immediately and the result will be fired as an event that you can pick up on the same or different event_socket connection or
other event consumer such as a custom C,perl,lua etc module.

3) You can use mod_xml_cdr to generate detailed 1-file-per-leg call files that will tell you when where and why the calls failed or did not fail.

Anthony / Michael,
Thanks for the quick responses. What I don't want to do is "drive the call" (by that listen on a socket ... do this on this event ... or anything else that my very limited FS foo would break) ... Just want to start it and then give it instructions on where to go.

So I guess a better question would be ... how do I give directions to FS for this (and I get the 1st part ... that's obvious ... really lost on the DTMF digit part) ... and please keep in mind we're talking hundreds of extensions / IVR's and distributed machines so I can't have any dependancy on static conf files other than maybe something like what Michael mentioned where I point every call to something:

[campaign]
exten => 100,1,ANSWER()
exten => 100,n,PLAYBACK(somefile)
exten => 100,n,BACKGROUND(somefile)
exten => 100,n,WAITEXTEN(4)
exten => 100,n,HANGUP()

but in that same context is someone triggers DTMF:
exten => 1,1,DOSOMETHING
exten => 2,1,DOSOMETHING

I was imaging issuing originate via XML_RPC ... something like originate sofia/$ANI@$IP $SOMEEXTEN then on answer when FS tries to connect to $SOMEEXTEN it will ask me what to do via xml_curl ... where I would normally respond with something like this:

<?xml version="1.0" encoding="UTF-8" standalone="no"?> <document type="freeswitch/xml"> <section name="dialplan" description="FS RESPONSE"> <context name="public"> <extension name="$EXTEN"> <condition field="destination_number" expression=""> <action application="set" data="hangup_after_bridge=true"/> <action application="set" data="continue_on_fail=true"/> <action application="set" data="call_timeout=180"/> <action application="set" data="proxy_media=true"/> <action application="set" data="pass_rfc2833=true"/> <action application="set" data="accountcode=$CUSTOMER" /> <action application="set" data="origination_caller_id_name=NULL" /> <action application="set" data="origination_caller_id_number=$CIDNUM" /> <action application="set" data="effective_caller_id_name=NULL" /> <action application="set" data="effective_caller_id_number=$CIDNUM" /> <action application="set" data="userfield=$BUNCHOFCRAPFORMYCDR" /> <action application="bridge" data="sofia/external/$ANI@$PROVIDERIP" /> </condition> </extension>
</context>

</section> </document>

The challenge I've got is I have no idea how to do stuff like the IVR mentioned above (the playback part is easy) ... but I can't grasp conceptually how to get the "context" with "multiple extensions" part back to FS via this method (is it possible?)...

Sorry for what is probably a very simple answer and any AST references (but I've been using it in heavy production environments for about 5 years). Just trying to "port" what I do today without making my brain melt out of my ears (and it doesn't take much for that to happen).

PS ... Really enjoy the list. I usually fall out of my chair laughing once a day from your remarks Anthony. Keep it coming!

Try it from the FS CLI first to see how to do it.

originate <dial string> <extension> <dialplan> <context>

so type this in the console replacing the sofia url with one of your choice:

originate sofia/default/100@dom.com (100@dom.com) 9998 XML default

when you answer the call you should hear the tetris song. so you can use any ext@context+dialplan combo with those args.

You can do the same over xmlrpc or mod_event_socket

I see your dilemma. To keep things dynamic you definitely want to use
your XML_CURL stuff. Like you said, nothing static.

Can you post a sample call-flow in plain English? I'm curious about
something. I don't want to say anything else. Just post a simple call
flow:
Initiate call
Wait for answer/busy/timeout/invalid
On busy/timeout/invalid: update db and move on
On answer play greeting, accept digit, route based on digit

Something like that would help me conceptualize what you are trying to do.

Thanks
MC

P.S. - I've done a little bit of outbound IVR calling so hopefully I
can assist you.

Thanks Michael.
Here are some really simple examples (we limit what people do through the web ... nothing really fancy ... just some good old fashion robo calls).
ultimately today it looks like this extensions_table (context, exten, priority, app, appdata):

campaign,100,1,ANSWER() --> answers call
campaign,100,2,WAIT(1) --> this is a pause
campaign,100,3,PLAYBACK($INTROFILE) --> plays intro file
campaign,100,4,BACKGROUND($MESSAGE) --> plays message
campaign,100,5,WAITEXTEN(5) --> WAIT for DTMF
campaign,100,6,HANGUP()
Here are DTMF options
campaign,1,SYSTEM($SCRIPT campaign $EXTEN)
campaign,2,SYSTEM($SCRIPT campaign $EXTEN)
campaign,3,DIAL,zap/g1/$ANI

anothercampaign,112,1,ANSWER()
anothercampaign,112,2,BACKGROUND($SOMEFILE)
anothercampaign,112,3,WAITEXTEN(5)
anothercampaign,112,4,HANGUP()
Options:
anothercampaign,1,DIAL(sip/$ANI@$IP)
anothercampaign,2,PLAYBACK($GOODBYE)


And they pretty much all look like that ... it's easy to return the stuff for extension 100 via XML ... but the challenge is the DTMF options (relating to the same context) ... or maybe I'm just missing something (which is a definite possibility). We don't ever do anything complicated in the IVRs (TTS or ASR) but there is just a lot of them that all get controlled, manipulated via a web interface.


I can originate a call ... do all of that ... just trying to figure out a "simple" way to return the above via xml.

Thanks for your help Anthony and Michael as always!

Shelby

its the same idea where i gave you that example to call 9998 call 1234 where your extension is delivered via curl when 1234 is requested
use the "read" and "transfer" apps in the xml you return, you can get it working statically first in your regular dialplan.

MC / Anthony,

Muchas gracias ... looks like I'm going to be on my way to being * free Ran a small production test today (about 20,000 dials) and going to get after it tomorrow with a real campaign.

You guys kick ass.

Thanks again for the assistance fine sirs.
