Please Help: TDM Hardware For Testing
by Michael Collins 17 Sep '09

17 Sep '09

Hello all! We could use your help with something. We've had several volunteers willing to assist with testing and debugging various scenarios with TDM circuits. However, there is a need to get TDM hardware into the hands of those volunteers. If you have old TDM hardware, be it analog or digital, that is sitting around collecting dust and you'd like to donate it (or loan it) to the cause then please email me off list. Thanks! -MC

ATTN: Debian gurus and enthusiasts
by Michael Collins 17 Sep '09

17 Sep '09

If you are a Debian person and have experience creating .debs then read on... Frank Carmickle has graciously volunteered to assist with creating a FS deb config. I've heard that others have been doing something similar or are interested. If you are such a person then please email Frank and me off list so that we can organize the volunteers. Thanks! -Michael

FreeSWITCH and radios
by Trixter aka Bret McDanel 16 Sep '09

16 Sep '09

I am working on a few things, when I have time I am integrating FreeSWITCh with ham radios. While this is not specific to ham radios, that is *my* intent. Potentially you can use FRS/GMRS, CB, commercial radios, whatever. If anyone is interested in doing this type of stuff I would ask that you contact me, and possibly check out what I have done so far: http://svn.freeswitch.org/svn/freeswitch/trunk/contrib/trixter/radio/ my goal is to build tools that enable people to quickly and easily integrate FreeSWITCH to build a repeater or some other radio appliance. In essence a radio would be YATE (Yet Another Telephony Endpoint) :D -- Trixter http://www.0xdecafbad.com Bret McDanel pgp key: http://pgp.mit.edu:11371/pks/lookup?op=get&search=0x8AE5C721

As always, we are looking for volunteers to assist with various sub-projects. All are invited to listen in on the weekly call.

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)

mod_odbc_query
by Leon de Rooij 15 Sep '09

15 Sep '09

Hi, I wrote a new module mod_odbc_query the last few days and I'm wondering what other people think of it. It works here, tested it and valgrind sees no leaks.. You can check it out here: http://fisheye.freeswitch.org/browse/FreeSWITCH/contrib/ledr/c/mod_odbc_que… It's pretty flexible and useful for me. regards, Leon --- mod_odbc_query readme This module can be used for doing odbc queries from the dialplan. Usage: <application name="odbc_query" data="SELECT some_column_name AS target_channel_variable_name FROM some_table_name WHERE 1;"/> or: <application name="odbc_query" data="my-query"/> The module simply checks whether the data attr contains a space. If it does, then that field will be seen as an SQL query, otherwise it will be seen as a query 'name' which then has to be defined in the modules configuration in the <queries> section like this: <queries> <query name="my-query" value="SELECT some_column_name AS target_channel_variable_name FROM some_table_name WHERE 1;"/> </queries> The module will do the query and store each returned column name as channel variable name together with its corresponding value. Another feature is, that if only two columns are returned, which have the column names "name" and "value", then the channel variables will be set according to them. This way you can have the query return multiple rows with different channel variables. If the query returns something else than column-names "name" and "value" and it returns multiple rows, then the channel variables will be overwritten with each iteration of the rows - which is probably useless. The query may contain ${blah} variables that will be expanded from channel variables before the query is performed. For example: query: "SELECT foo, bar FROM huk WHERE tilde='kek';" returns: foo bar ---------- a b c d then the channel variables that will be set are: foo=c bar=d --- query: "SELECT foo AS name, bar AS value FROM huk WHERE tilde='kek';" returns: name value ------------ a b c d then the channel variables that will be set are: a=b c=d --- So, the first example should only be used when you know that only zero or one row will be returned, and second one if you know zero or more rows will be returned. If zero rows are returned (in either foo/bar or name/value case) then no channel variables will be set, overwritten or deleted. --- <configuration name="odbc_query.conf" description="ODBC Query Module"> <settings> <param name="odbc-dsn" value="freeswitch:freeswitch:secret"/> </settings> <queries>  <query name="map-did-users" value=" SELECT dir_users.username AS dest_user, dir_domains.name AS dest_domain FROM map_did_users, dir_domains, dir_users WHERE map_did_users.did='${destination_number}' AND dir_users.id = map_did_users.user_id AND dir_domains.id = dir_users.dir_domain_id;"/> </queries> </configuration>

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

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

How to get busy profiles in mod_dingaling
by Muhammad Shahzad 14 Sep '09

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? Thank you. -- Muhammad Shahzad ----------------------------------- CISCO Rich Media Communication Specialist (CRMCS) CISCO Certified Network Associate (CCNA) Cell: +92 334 422 40 88 MSN: shari_786pk(a)hotmail.com Email: shaheryarkh(a)googlemail.com
