The problem is that I'll also need to see where in the dialplan each channel is up to and then from there relate back to customers. With "show channels" this other info is also provided - although I'll look into mod_limit. >> esl_send_recv(&ser->handle, "bgapi originate >> {variable_accountcode=bar}sofia/internal/1000%x.x.x.x 9999\n\n"); >> >> Then the accountcode is blank - maybe because it is initially set up >> without one and the variable is set later? > > where is it blank?

Yeah, basically the patch just copies the accountcode into the channel in the sqlite db. I'd love to be able to do it some other way! I'm not in any way tied to making it work like Asterisk :) In fact I have even created a new SVN branch for dealing with this even though the code will support both Asterisk and FreeSwitch :) I'll have a look at mod_limit and maybe that's a better place to patch if need be. -- Cheers, Matt Riddell Director _______________________________________________ http://www.venturevoip.com/news.php (Daily Asterisk News) http://www.venturevoip.com/st.php (SmoothTorque Predictive Dialer) http://www.venturevoip.com/c3.php (ConduIT3 PABX Systems)

[Freeswitch-dev] Add accountcode to Show Channels
by Matt Riddell 15 Sep '09

15 Sep '09

Hi, I opened a bug with a patch (which admittedly will need some extra work), but wondered if I've maybe stepped on someone's toes, or if I should be approaching the problem in a different manner. Basically what I'm trying to achieve is this: (this particular implementation is to replace Asterisk for an emergency warning broadcast system) 1. Originate a call (with accountcode to specify which customer of a multi tenanted system should be billed). 2. Check how many calls the system currently has (broken down by accountcode so that I can restrict individual accounts). I realise that I could keep a lookup table of UUID to customer on origination, but if we're doing thousands of calls in a short period of time the list would become huge (we're load balancing calls across multiple freeswitch machines), and I'd rather keep the data sent to/from each machine to a minimum. So, in Asterisk the way we do it is "show channels concise" which provides a list of channels with their details (much the same as freeswitch), but also provides the accountcode which allows me to group the calls. By the way, the format for return from "show channels" is fantastic, the code on my side now looks at the header line once (the first time it checks channels) and compares each field to the list I expect. This means that even if the order of the fields is different on different machines, I'll still get the expected results. Anyway, so I put together a super small patch to add in the accountcode, but get the feeling that it's not useful. It's available here: http://jira.freeswitch.org/browse/FSCORE-438 I noticed that if you have a call originated by a softphone, the accountcode comes from the configs, and this gets passed to the show channels no problems. However, if I set it in the originate, i.e.: esl_send_recv(&ser->handle, "bgapi originate {variable_accountcode=bar}sofia/internal/1000%x.x.x.x 9999\n\n"); Then the accountcode is blank - maybe because it is initially set up without one and the variable is set later? Anyway, so where to from here? Should I keep working on it (I'd likely need some assistance, but am willing to do whatever it takes), or is there a better way to do it that I'm not seeing because of no0bness to FreeSwitch? Thanks for your time. -- Cheers, Matt Riddell Director _______________________________________________ http://www.venturevoip.com/news.php (Daily Asterisk News) http://www.venturevoip.com/st.php (SmoothTorque Predictive Dialer) http://www.venturevoip.com/c3.php (ConduIT3 PABX Systems)

[Freeswitch-dev] Controlling FS from C#, creating users and conferences
by Craig Presti 15 Sep '09

15 Sep '09

Hi all, I've been playing with mod_managed from C# to build a proxy for FS that I use to create users and conferences on demand. Currently I use the approach of generating an xml file in the appropriate folder under conf and then executing a reloadxml command via: api.executestring("reloadxml") I'm wondering if there is perhaps a better approach and what sort of danger is involved with a reloadxml command for users that are on an existing conference call? Cheers, Craig

[Freeswitch-dev] ATTENTION BEHAVIOR CHANGE of sip_invite_params variable.
by Brian West 14 Sep '09

14 Sep '09

I just committed revision 14849 to make sip_invite_params only apply to the RURI, If you wish to modify the To param son the invite you MUST use sip_invite_to_params moving forward. you have sip_invite_contact_params and sip_invite_from_params to work with also which were already there just making sure you know that now. Thanks, Brian West

[Freeswitch-dev] How to get busy profiles in mod_dingaling
by Muhammad Shahzad 14 Sep '09

Hi, How can we determine if a mod_dingaling profile is busy, i.e. in a call or locked somehow due to which it can not be deleted during a reload?

[Freeswitch-dev] mod_event_socket C API
by Dan White 12 Sep '09

12 Sep '09

http://wiki.freeswitch.org/wiki/Event_socket_outbound mentions that "someone working on a C library to use as an event socket library". What is the status of that library? If still under progress, is the API for the library available? I'm trying to get a feel for what the API will look like, in preparation of a future project that will make use of the outbound event socket. Thanks, -- Dan White

[Freeswitch-dev] Event-socket uuid problem
by Mathieu Lautram 11 Sep '09

11 Sep '09

Hi there, Here is my problem: I'd like to set up a switchboard. I'm using python scripts called when a call is coming. Here is my public.xml: *<extension name="toto"> <condition field="destination_number" expression="[0-9]*"> <action application="python" data="test.test2" /> </condition> </extension>* Next, in my test2.py, I put the uuid of the session in a database: *import os, cgi, MySQLdb, time from freeswitch import * def handler(session, args): uuid = session.getVariable("uuid") myconnection = MySQLdb.connect(host = "localhost", user = "root", passwd = "root", db = "testfreeswitch") mycursor = myconnection.cursor() mycursor.execute("INSERT INTO fileAttente VALUES (NULL, '0123456789', 'LIBRE', '" + uuid + "')") session.execute("park")* Everything runs fine from here. After this, I use telnet to have a connection to freeswitch. And... I'm stuck. I would like this: a file corresponding to the caller (test2) a file corresponding to the callee; This file will be pretty much the same that test2. a file which will be run in the same time that Freeswitch; This file will dialog with Freeswitch and the database. The real problem that I have is that I don't know how to create a new session corresponding to the callee (via a python script). If somebody could help me, it could be really great =) Thanks a lot Mathieu
