Kudos to the FreSWITCH team!
by David Villasmil 03 Jan '13

03 Jan '13

Hello FS team, I'm just writing thie short email to congratulate you guys for the amazing work you're doing with FS since the very beginning. As some of you may know, some time ago I developed the FreeSWITC-Billing platform on top of FreeSWITCH (although it's been some time since I updated it). Some of my customers have been using it for 2 years now and have good traffic running on it. Long story short, I was called by 2 of my customers who were in turn called by a couple of their providers asking to please, please, pretty please slow doen the rate with which my customers were sending calls to them or to limit the channels, because my customers were bringing their soft-switches DOWN... I don't know the other switch's brand , but I know one is a Quintum. So, like I said: KUDOS! Cheers to all and Happy New Year!! David Villasmil https://github.com/davidcsi/FreeSWITCH-Billing

Problem with Polycom
by Abaci 03 Jan '13

03 Jan '13

We have OpenSIPS in front of FreeSWITCH, phones register to OpenSIPS, OpenSIPS sends all calls to FreeSWITCH. the way we have it set up is that both OpenSIPS and FreeSWITCH auth all the invites (we have it like this for a reason). this setup works fine (with Yealink at least). Problem we have is with Polycom phones, the phone registers just fine but can't make calls. When OpenSIPS gets the INVITE it responds with a 407, to which the Polycom responds, OpenSIPS is then sending the call to FreeSWITCH which sends a 407 again, OpenSIPS proxies it back to the polycom, however the Polycom does not respond to the challenge. I don't think this is a FreeSWITCH problem, I would still like to hear if anyone has an idea how I can get this working (config option?) Thanks

Sofia fails to detect offline gateway
by Steven Ayre 03 Jan '13

03 Jan '13

Hi Guys, A couple of our gateways have been shut down for hardware upgrades. However, the FreeSWITCH servers didn't spot the gateways go offline so they're still trying to send calls to them. I see this in the logs: 2011-01-11 09:35:05.396610 [WARNING] sofia.c:3981 Ping failed gw4 with code 503 - count 1/0/10, state UP 2011-01-11 09:35:05.396610 [WARNING] sofia.c:3981 Ping failed gw3 with code 503 - count 1/0/10, state UP 2011-01-11 09:35:13.408674 [WARNING] sofia.c:3981 Ping failed gw4 with code 503 - count 1/0/10, state UP 2011-01-11 09:35:13.408674 [WARNING] sofia.c:3981 Ping failed gw3 with code 503 - count 1/0/10, state UP 2011-01-11 09:35:21.420884 [WARNING] sofia.c:3981 Ping failed gw4 with code 503 - count 1/0/10, state UP 2011-01-11 09:35:21.420884 [WARNING] sofia.c:3981 Ping failed gw3 with code 503 - count 1/0/10, state UP 2011-01-11 09:35:29.458114 [WARNING] sofia.c:3981 Ping failed gw4 with code 503 - count 1/0/10, state UP 2011-01-11 09:35:29.458114 [WARNING] sofia.c:3981 Ping failed gw3 with code 503 - count 1/0/10, state UP 2011-01-11 09:35:37.472424 [WARNING] sofia.c:3981 Ping failed gw4 with code 503 - count 1/0/10, state UP 2011-01-11 09:35:37.472424 [WARNING] sofia.c:3981 Ping failed gw3 with code 503 - count 1/0/10, state UP 2011-01-11 09:35:46.475934 [WARNING] sofia.c:3981 Ping failed gw4 with code 503 - count 1/0/10, state UP 2011-01-11 09:35:46.475934 [WARNING] sofia.c:3981 Ping failed gw3 with code 503 - count 1/0/10, state UP 2011-01-11 09:35:55.489967 [WARNING] sofia.c:3981 Ping failed gw4 with code 503 - count 1/0/10, state UP 2011-01-11 09:35:55.489967 [WARNING] sofia.c:3981 Ping failed gw3 with code 503 - count 1/0/10, state UP ... you get the idea. I've done some testing and it happens both when FS is running and the gateway goes offline (code 408 then) and when FS starts up with the gateway already offline (code 503 as above). Both IP addresses are entirely offline. I had expected these would go to state DOWN but they haven't, I just get the above repeating. The gateway definitions look like this: <gateway name="gw3"> <param name="realm" value="a.b.c.d"/> <param name="username" value="nouser"/> <param name="password" value="nopass"/> <param name="register" value="false"/> <param name="caller-id-in-from" value="true"/> <param name="ping" value="5"/> <param name="ping-max" value="10"/> <param name="ping-min" value="1"/> <param name="retry-seconds" value="5"/> <param name="expire-seconds" value="60"/> </gateway> Is there a mistake in my configuration? -Steve

Naming convention - sip_profile_name / sofia_profile_name / sip_gateway_name
by Cal Leeming [Simplicity Media Ltd] 03 Jan '13

03 Jan '13

Hello, The following ticket has been raised in regards to the somewhat confusion naming convention of sip_profile_name / sofia_profile_name / sip_gateway_name. http://jira.freeswitch.org/browse/FS-4980 To avoid confusion, I have also updated the documentation to reflect the current behavior; http://wiki.freeswitch.org/wiki/Variable_sofia_profile_name http://wiki.freeswitch.org/wiki/Variable_sip_profile_name http://wiki.freeswitch.org/wiki/Variable_sip_gateway_name If anyone spots any mistakes in the above, please let me know.

I must be getting closer to getting this to work, because now I get this message: 2012-12-28 15:18:23.596375 [WARNING] sofia_reg.c:2485 Can't find user [ 103(a)xx.com] You must define a domain called 'xx.com' in your directory and add a user with the id="103" attribute and you must configure your device to use the proper domain in it's authentication credentials.

Newbie question: Executing Lua scripts for incoming calls, how concurrency is to be handled?
by Sirish Masur Mohan 02 Jan '13

02 Jan '13

Hello All, I am a newbie to FreeSWITCH, please excuse if this question has already been answered. My requirement is as follows: * When an incoming call is received, it needs to be bridged to one of the 4 available destination lines * Minimal management of these lines is required: need to keep track of when each line was used, so that, when a new incoming call is received, I can use the oldest used available line to bridge the call to In order to achieve this, I have: * Defined a few global variables in vars.xml, which would keep track of each line's status (available/busy) and last used timestamp * Implemented a Lua script which 'chooses' the line based on global variables status and timestamp (using "global_getvar") and update the status of the line to be used (using "global_setvar") * Bridge to the line returned by the script * Execute another Lua script on hang-up, which updates the global variables I am now wondering if I would run into issues in cases where I receive concurrent calls (I am using a Sangoma E1 card, and will receive multiple concurrent calls soon)? Would I need to be applying some kind of explicit mutex protection in these scripts for the global variables? Thanks in advance! With regards, Sirish

uuid_record and RECORD_STEREO
by Luca Pradovera 31 Dec '12

31 Dec '12

Hello, is there a way to invoke uuid_record through bgapi, setting RECORD_STEREO to true as a local parameter instead of using uuid_setvar, over inbound Event Socket? I would prefer to not set a global state on the channel if possible. Thanks! -- Luca Pradovera luca.pradovera(a)gmail.com
