Limit application usage in Lua
by Florent Krieg 14 Mar '15

14 Mar '15

Hi all, I wanted to implement call rate limits using this Lua instruction: session:execute("limit", "hash " .. billedcaller .. " caps 10/1 !REQUESTED_CHAN_UNAVAIL") It is actually working, but the rest of the Lua dialplan is still processed, which is a problem in my case. I made a dirty but quick workaround, looking like this: rate_var = session:getVariable("limit_rate_" .. billedcaller .. "_caps") if not rate_var then logz("[Calls limit] CAPS limit reached for " .. billedcaller .. ", aborting the dialplan.") return end How can it be done properly? Is there a way to be able to get the result of the 'limit' app call? Or shall I check the status of the a-leg just after to decide to process the rest of the dialplan or not? I know that this issue doesn't occur in a 'pure' XML dialplan, but I'm trying to find a solution for my Lua-only dialplan. Thanks in advance if you have any idea. I'm willing to try any possible solution you would think about! Florent

I'll go dig it up when I have time, but if someone has it please post it on the JIRA.

Doc-Sprint Friday 13 March 2015
by Areski 13 Mar '15

13 Mar '15

Hi Everyone, We are *now* running a small Sprint to work on FreeSWITCH Documentation. It will be 2-3 hours long. The Doc-sprint will focus on migrating the remaining pages from old FS Wiki (https://wiki.freeswitch.org) to Confluence ( https://freeswitch.org/confluence) We will use this IRC channel during the sprint: #freeswitch-docs and we will be tracking our work on a spreadsheet: https://docs.google.com/spreadsheets/d/1qsG-kRymvKlNBapnBLw86W130VdbnK6naYa… to avoid working on the same content. So during the sprint, please change the page "Status" you are working on to "Editing" with your name next to it. Some extra information: - https://freeswitch.org/confluence/display/FREESWITCH/Wiki+Migration - https://freeswitch.org/confluence/display/FREESWITCH/Contributing+Documenta… Let us know if you have any question. Please join in :)

JAVA & WebRTC & JAIN SIP - no WebSockets
by Oleg Blinnikov 13 Mar '15

13 Mar '15

Hi, I've made a simple Android Java application utilizing JAIN SIP, webrtc.org android library and connected to FreeSwitch via UDP. But when I send SDP from SIP/Chrome/Firefox phone to my JAIN SIP client this SDP is not managed well by FreeSwitch for establishment WebRTC PeerConnection. When I call `peerConnection.setRemoteDescription(new SDPObserver(), sdp);` in my Android Application with the SDP from FreeSwitch I get: "onSetFailure Failed to set remote offer sdp: Called with SDP without DTLS fingerprint." At the same time the calls between Chrome/Firefox(http://tryit.jssip.net/) and SIP-phone (e.g. linphone) greatly managed by FreeSwitch and I have pure audio flow. Here is initial SDP from Chrome (http://tryit.jssip.net/) v=0 o=- 6887715720880489867 2 IN IP4 127.0.0.1 s=- t=0 0 a=group:BUNDLE audio video a=msid-semantic: WMS itEKr0vXP6lg3KNs4kVau9aL3uAfyWOlItfU m=audio 38359 RTP/SAVPF 111 103 104 0 8 106 105 13 126 c=IN IP4 192.168.122.1 a=rtcp:38359 IN IP4 192.168.122.1 a=candidate:4062413514 1 udp 2122260223 192.168.122.1 38359 typ host generation 0 ....... a=candidate:3741779331 2 tcp 1518018303 172.17.42.1 0 typ host tcptype active generation 0 a=ice-ufrag:bwrCv9yS8rCY12Az a=ice-pwd:3k35jpG/i+TCbvBcJPWrw2eP a=ice-options:google-ice a=*fingerprint*:sha-256 52:8C:0F:27:C6:D6:CF:AE:F4:87:AC:AE:DF:7B:9B:B2:75:90:60:6A:2A:82:09:98:AD:04:0B:35:45:6A:13:A2 a=setup:actpass a=mid:audio a=extmap:1 urn:ietf:params:rtp-hdrext:ssrc-audio-level a=extmap:3 http://www.webrtc.org/experiments/rtp-hdrext/abs-send-time a=sendrecv a=rtcp-mux a=rtpmap:111 opus/48000/2 a=fmtp:111 minptime=10 a=rtpmap:103 ISAC/16000 a=rtpmap:104 ISAC/32000 a=rtpmap:0 PCMU/8000 a=rtpmap:8 PCMA/8000 a=rtpmap:106 CN/32000 a=rtpmap:105 CN/16000 a=rtpmap:13 CN/8000 a=rtpmap:126 telephone-event/8000 a=maxptime:60 a=ssrc:1291334905 cname:ALccmKLk9bGpSGWB a=ssrc:1291334905 msid:itEKr0vXP6lg3KNs4kVau9aL3uAfyWOlItfU 4e8f212e-746a-47bb-bc62-4a42d4e9e84e a=ssrc:1291334905 mslabel:itEKr0vXP6lg3KNs4kVau9aL3uAfyWOlItfU a=ssrc:1291334905 label:4e8f212e-746a-47bb-bc62-4a42d4e9e84e m=video 38359 RTP/SAVPF 100 116 117 96 c=IN IP4 192.168.122.1 a=rtcp:38359 IN IP4 192.168.122.1 a=candidate:4062413514 1 udp 2122260223 192.168.122.1 38359 typ host generation 0 ............ a=candidate:3741779331 2 tcp 1518018303 172.17.42.1 0 typ host tcptype active generation 0 a=ice-ufrag:bwrCv9yS8rCY12Az a=ice-pwd:3k35jpG/i+TCbvBcJPWrw2eP a=ice-options:google-ice a=*fingerprint*:sha-256 52:8C:0F:27:C6:D6:CF:AE:F4:87:AC:AE:DF:7B:9B:B2:75:90:60:6A:2A:82:09:98:AD:04:0B:35:45:6A:13:A2 a=setup:actpass a=mid:video a=extmap:2 urn:ietf:params:rtp-hdrext:toffset a=extmap:3 http://www.webrtc.org/experiments/rtp-hdrext/abs-send-time a=recvonly a=rtcp-mux a=rtpmap:100 VP8/90000 a=rtcp-fb:100 ccm fir a=rtcp-fb:100 nack a=rtcp-fb:100 nack pli a=rtcp-fb:100 goog-remb a=rtpmap:116 red/90000 a=rtpmap:117 ulpfec/90000 a=rtpmap:96 rtx/90000 a=fmtp:96 apt=100 Here is SDP received from FreeSwitch in JAIN SIP via UDP: v=0 o=FreeSWITCH 1425524563 1425524564 IN IP4 192.168.131.253 s=FreeSWITCH c=IN IP4 192.168.131.253 t=0 0 m=audio 16390 RTP/AVP 111 0 8 101 13 a=rtpmap:111 opus/48000/2 a=fmtp:111 minptime=10 a=rtpmap:0 PCMU/8000 a=rtpmap:8 PCMA/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=ptime:20 m=video 16388 RTP/AVP 100 a=rtpmap:100 VP8/90000 I suppose that FreeSwitch wants to see WebRTC connection only on the WebSocket ports and it doesn't know that my UDP client is actually WebRTC client. So I'm wondering if it possible to connect SIP client to the WebSocket port via TCP using standard SIP client and never upgrade connection to WebSocket? Regards, Oleg

Re: [Freeswitch-users] illegal instruction
by Andrew 13 Mar '15

13 Mar '15

Thanks, I looked and its set to "NOT SET". I do know the CPU is a AMD that is having an issue. Not sure if the other server is an Intel or not. Andrew From: Andrew [mailto:aademattia@Comcast.net] Sent: Sunday, March 8, 2015 3:36 PM To: 'FreeSWITCH Users Help' Subject: illegal instruction Hi, I have an odd issue. I was going to run out of the box FreeSWITCH on a windows server and just by double clicking on freeswitch.exe I get a crash. When I did a debug I found it was illegal instruction error. If I remove mod_spandsp The program starts up fine. I then try to do a tone detection and then the program crashes again. What would cause the same release code to work on one server but crash on another server? Andrew

failover in freeswitch dialplan using | or lcr
by Jason Holden 13 Mar '15

13 Mar '15

Hi, If I send an invite for a call and don't receive a response to the initial invite message how can I force FS to try the next route right away? Here is one of my lcr dialplan chunks. <condition field="destination_number" expression="^(.*)$"> <action application="set" data="continue_on_fail=true"/> <action application="set" data="hangup_after_bridge=true"/> <action application="set" data="domain_name=$${domain}"/> <action application="set" data="instant_ringback=true"/> <action application="ring_ready" /> <action application="set" data="ringback=${us-ring}"/> <action application="set" data="transfer-ringback=${us-ring}"/> <action application="lcr" data="$1 inbound"/> <action application="set" data="bypass_media=true"/> <action application="bridge" data="${lcr_auto_route}"/> </condition> </extension> All advise is welcome, thanks.

Values of read_codec/write_codec on different FS versions...
by Vladimir Getmanshchuk 13 Mar '15

13 Mar '15

Hello Everyone! I have two installations of FS with absolutely identical configurations. Both has SIP profiles with proxy-media enabled. But on freeswitch@internal> version FreeSWITCH Version 1.4.15~64bit ( 64bit) I have values in read_codec/write_codec variables at CDRs: "read_codec":"PROXY","write_codec":"PROXY" but on another one freeswitch@internal> version FreeSWITCH Version 1.4.5~64bit ( 64bit) I have: "read_codec":"G729","write_codec":"G729", "read_codec":"PCMA","write_codec":"PCMA", etc... So Why? -- Yours sincerely, Vladimir Getmanshchuk
