Gsmopen: K3520 automatic device discovery
by Johannes Stads 25 Sep '13

25 Sep '13

Hello. I've built FS on a CentOS 6.4 virtual machine (MacOS 10.8 Parallels) using minimal config for testing with Huawei K3520 dongle. It was initially unlocked (Vodafone DE) and voice enabled by default. Using manual USB port config all worked fine including calls and sms, voice quality was good. It uses USB2 port for modem, and USB1 for audio. I tried to attach 2 dongles, made used rules and that worked fine too, however this scenario does not guarantee the same order in which dongles are seen after each reboot. Automatic device discovery does not seem to work with that dongle. I specified IMSI for each dongle, or IMEA, or both. Every time mod_gsmopen tries to use /dev/ttyUSB3 which is not a proper choice for those dongles. I can see K3520 in the list of supported dongles. Maybe something I do wrong. Any idea? Jo

Freeswitch Port
by Andre 25 Sep '13

25 Sep '13

What is the variable to find the SIP port in a dial plan? I'm looking for the 5060 port (assuming I didn't change it in the profile).

"Upgrade" from 1.3b to 1.2stable caused higher cpu usage
by Freddy Andersen 25 Sep '13

25 Sep '13

Hi, We have 5 Freeswitch servers running with about 500 concurrent calls total so about 100 each at peak. These servers was installed with version FreeSWITCH Version 1.3.13b+git~20130215T194756Z~9733740cab (git 9733740 2013-02-15 19:47:56Z) and they have been running fine with 250% cpu (out of 2400%), load average hits 3 at peak. We wanted to get our Freeswitch onto a stable release and thought 1.2.12 was the most stable version so this is what we installed on one server. This servers cpu is at 800-900% and load average hits 10 when the server runs with 1.2.12, if we rollback cpu goes back to old 2-300%.. Call quality is still ok but I feel we have less room for more load and upgrading should normally improve performance not decrees performance. Just as an experiment I also tried to install latest 1.4 thinking this might have been something in the 1.2 branch but 1.4 acts the exact same. here is a quick vmstat snapshot: procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 15 2 0 430144 321280 9988432 0 0 3 33 1 1 11 3 87 0 7 0 0 425160 321344 9991936 0 0 56 116 67726 113824 30 4 66 0 22 0 0 424380 321368 9993580 0 0 28 0 84236 148377 25 4 70 0 19 0 0 423656 321404 9994324 0 0 32 0 61714 103954 23 2 74 0 9 0 0 422740 321444 9996020 0 0 24 1524 52116 86355 23 2 74 0 7 0 0 421908 321456 9997160 0 0 20 5524 58977 98786 22 2 76 0 10 0 0 420812 321464 9998244 0 0 4 0 52964 83640 23 2 75 0 21 0 0 417152 321496 9999184 0 0 56 36 73430 124669 25 3 71 0 6 0 0 417496 321516 10000704 0 0 20 0 78778 134441 27 3 69 0 This is from sometime, same calls but from a freeswitch 1.3 server: procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 3 0 244 2668752 269200 4589652 0 0 7 60 1 0 14 3 83 0 4 0 244 2666192 269228 4590676 0 0 64 12 44941 50134 24 4 72 0 3 0 244 2670200 269256 4592680 0 0 28 24 62350 86122 34 4 62 0 4 0 244 2668584 269280 4593848 0 0 20 0 43495 53052 27 2 70 0 6 0 244 2664636 269332 4595884 0 0 32 5576 53941 67240 26 4 70 0 8 0 244 2665316 269380 4596720 0 0 40 68 66434 91266 31 4 64 0 3 0 244 2666780 269404 4597792 0 0 24 0 41862 48055 23 3 74 0 -- - Freddy

Re: [Freeswitch-users] inherit_codec failing with pre-media

Did I explain a bit to much detail for the users list? Does anyone use "inherit_codec=true" and have it working?

Help with MOH
by JP 25 Sep '13

25 Sep '13

I am trying to play MOH on a leg after bridge. Here are the steps 1. I "originate" a call( Call-A ). 2. I then "bridge" it to another call (Call-B). I have set "park_after_bridge=true". 3. After a while, I "transfer" the Call-B to a dialplan extension where I just "playback" moh as follows... <action application="playback" data="local_stream://moh" /> The problem is that I don't hear the moh on leg B even though I observe that the calls are un-bridged. It looks like both the calls remain in park state. Any help appreciated. Thanks JP

Incomplete Hangup(Customer/Caller Still Active)
by Arpit Gadle 25 Sep '13

25 Sep '13

Dear All, When an agent receives,an incoming call he hangsup/disconnect/ignore without answering. The call is clear at agent's end and he is ready for another call but the call is still active at caller/customer end. * *I tried disconnecting the active call by "fsctl hupall normal_clearing" but failed, I also tried transfering call to to other extension in dialplan and hangup from there but no result. Any help is appreciated. Thanks & Regards, Arpit Gadle

No TALK and NOTALK events are fired
by mathieu virard 24 Sep '13

24 Sep '13

Hi, I'm trying to get TALK and NOTALK events but it seems that theses events are never fired. That's what I've done so far: - add the line "<param name="vad" value="both"/>" under settings in my sip profile - add the lines "<action application="set" data="fire_talk_events=true"/> and <action application="set" data="fire_not_talk_events=true"/> " to my dialplan (I also tried with "export" instead of "set", and i tried to use the "rtp_enable_vad_out" variable without success) - I started a the fs_cli.exe console and typed: "/event talk" and "/event notalk" - I established a call which uses the modified sip profile and dialplan. I alternatively speak on the microphone and mute it, but i can't see any event on the console but the hearbeats (i also activate "/event heartbeat" to be sure that event are well displayed) Has someone an idea about what i did wrong / missunderstood? My intention is to detect inactivity on the call and to process this event in an external application connected to freeswitch. Thanks in advance for any help! Cheers, mathieu

Issue with auth-calls false
by Trevor Benson 23 Sep '13

23 Sep '13

I am having trouble creating an unregistered external gateway in FS. I went through the wiki and found that auth-calls and ACL's looks like the proper way to achieve this. I set auth-calls to false in both internal & external, added an ACL into domains to allow the cidr of the gateway in question. However after the gateway sends the Invite, FS always sends a 407 Proxy Auth back to the gateway. I checked into the IRC channel and one or two nice folks reviewed the config and said they thought it should be working, but the call still fails on Proxy Auth 407. The SIP Trace, external, internal & gateway profile from the test system are available at http://pastebin.freeswitch.org/21443 All suggestions are welcome, Trevor

Freeswitch RTP endpoint linked to another RTP endpoint
by Danny Gershman 23 Sep '13

23 Sep '13

So I have an INVITE that comes in that doesn’t have SDP in it. I have the “enable-3pcc” turned on so FreeSWITCH does respond properly. So then it responds with SDP allocating an endpoint. Then I take that SDP information and I turn around and send a new INVITE with the SDP in it. The hopes is that this endpoint is then bridges to a new endpoint. Essentially Freeswitch is connected to itself. Here is the pastebin - http://pastebin.freeswitch.org/21327 Look at the CreatePlayConnectionForConference:1 in the User-Agent field. And then look at the CreatePlayConnectionForConference:2. Those two are supposed be linked together with RTP.
