Hi All, I am familiar with Asterisk and doing some testing for my next project. I have had some difficulties Asterisk, and now researching FreeSwitch hoping that it has some out-of-the box answers for my questions. Basically I want to implement a Click 2 Call service. Very simple, user types in his/her number on a website, that number is called, after it's answered, the company number is called and they are bridged together. 1) Is there a way to communicate with FreeSwitch programatically and issue commands such as initiate calls etc ? (ver much like manager API in Asterisk) 2) If you initiate a call from the software and then once its answered call a 2nd number. How do you bridge them? 3) After the 2 numbers talk and hang up. How does your cdr look like? Do you have 2 cdr's that correspond to both calls or just 1 after both numbers are bridged together? This is one of the problems I can't solve with Asterisk as it generates only 1 cdr after the 2 calss are bridged. The reason for this request is, in case of a Click2Call service, you are charged for both calls by your SIP provider therefore you need to be able to track both calls for invoices/payments etc. 4) Is there a way to programatically know if a call has been asnwered or not and act based upon that. I understand the cdr contains that information. But what I want is, if the call is not answered maybe I can play a prerecorded message or take them to the voicemail or whatnot. So I need a way to do a flow-control based on if the call has been asnwered or not in the dialplan. Does that exist? If so can you point me to some resources? Thanks, Vito A.

There is an interface that we call the fsapi interface that can be accessed in many ways, including over a socket method similar to a combination of AMI and FAGI:

http://wiki.freeswitch.org/wiki/Event_Socket

and xmlrpc:

You can do this all in one command:

We can do either per leg or combined cdr's

http://wiki.freeswitch.org/wiki/Channel_Variables#process_cdr

We have multiple supported formats for cdr:

http://wiki.freeswitch.org/wiki/Mod_xml_cdr
http://wiki.freeswitch.org/wiki/Mod_cdr_csv

Michael,

Thanks a lot for the answers, it answers my questions, I guess the next thing would be downloading and trying FS Smile

Also, as I saw in the wiki, there is no built in support for mysql right? The solution that was suggested was setting up a cron to import the csv files into mysql, is this still what's available or are there any updates on this?

Thank,

Vito A.

Another way would be to export to a Radius server using a MySQL backend.

I am not using the feature so I can not report how well it works but I
am confident that "it should just work" and that if it does not, it will
be fixed Smile

There are several approaches you could take to this. You could do this
all in dialplan if there is not any real forking other than if the call
worked. You can use the variables:

http://wiki.freeswitch.org/wiki/Channel_Variables#hangup_after_bridge
http://wiki.freeswitch.org/wiki/Channel_Variables#continue_on_fail

and just playing the sounds in the dial-plan after a bridge line.
