Verto Qs
by Rick Jarvis 21 Sep '17

21 Sep '17

Ok I’ve asked a lot of questions about Verto, so I thought I’d summarise my current confusions here - if anyone can give me any pointers on any of these inline, that would be amazing! :) 1. Correct way to list all conference members via wss? 2. How to check if there is a current verto session / call in progress, and make the call if not. 3. Difference between :7443 and :8082 (is one for signalling and one for audio?) I have just purchased the latest FS book, 1.8, so hoping that will help also :) Thanks R

Dear All, FreeSWITCH Version 1.6.17-34-0fc0946~64bit (-34-0fc0946 64bit) How can I get below channel variables in dialplan? Caller-Callee-ID-Number: Other-Leg-Callee-ID-Number: Other-Leg-Destination-Number: variable_last_sent_callee_id_number: Thanks!

Session recording performance
by Stanislav Sinyagin 20 Sep '17

20 Sep '17

I'm building an environment for voice quality testing, and found a strange behavior. Maybe someone has an explanation. Two identical physical computers (PC Engines APU2), connected back to back (A and B). A initiates the test calls to B's SIP address, and then both ends go through a small dialplan (less than 100 lines of XML, similar to https://github.com/voxserv/fsqa/blob/master/fsqa.xml and start recording the session. The dialplan initiates session recording to a Raw file, and plays back a 20-second audio sample, and then inserts the filename into a Redis queue, then hangs up. Then the files get processed by Sevana AQuA software in lowest CPU priority, and deleted. The files are written into a tmpfs filesystem. With 2 calls per second, I get 48 simultaneous calls, and B indicates frame drops in the audio recordings, while A shows good results. The CPU average idle time is always above 50% on both computers. Why is the B side (the one receiving INVITEs) getting more frame drops than the A (the one originating the calls)? I flipped the sides, and then the other machine started to get more drops. At first I started recording in WAV format, and similar effect started to appear at a call every 2 seconds, resulting in 12 simultaneous calls. With raw recording, the performance is much better, but still it's a mistery why there are dropped frames in the audio. The CPU is always running at its highest frequency, under "performance" governor.

sox L16 to G711, inconsistent results
by Stanislav Sinyagin 20 Sep '17

20 Sep '17

In order to utilize mod_native_file, I converted the original L16 8000Hz audio into G711 with sox: sox ${SRCFILE} -t raw -r 8k -b 8 -c 1 -e u-law ${DSTDIR}/${BASENAME}.PCMU I just discovered that if I do this command twice and compare resulting files, they differ. They also differ if I take 44100Hz source audio. Anyone got a clue what's going on? FreeSWITCH is always producing the same bitstream when converting L16 to G711.

Unable to catch extra sip headers
by Aqs Younas 20 Sep '17

20 Sep '17

Greetings list, I am trying to catch extra sip header in dialplan but of no avail. I have tried info app and uuid_dump on the call to make show variables are appearing in console, but they were not. Though I can see header in sip trace when i run "sofia global siptrace on". This is how it is appearing in sip trace. 2017/09/20 11:22:37.025662 35.189.47.13:5060 -> 10.240.0.23:5063 INVITE sip:0061862083277@sip99.mondotalk.com:5060;transport=udp SIP/2.0 Record-Route:

RTP Loss with Freeswitch in Default Mode
by vikas sharma 20 Sep '17

20 Sep '17

Hi I am using Freeswitch in Default mode for video calls.But while i am making video calls using two linphone applications on android mobile phone with H264 codec support ,video is getting stuck in between the calls on linphone i.e video is not continuous. *aleg*:*bleg*: Here is my analysis on RTP packet dump taken on the Freeswitch server side: 1. Audio RTP received on *A leg*= *5184* but* forwarded *on *B leg *= 5005 + 35(*private port*) =* 5040*. 2. Audio RTP received on* B leg* = *5178* but forwarded on* A leg* = 4763 + 68(*private port*) = *4831*. 3. Video RTP received on* A leg* = *3145* but forwarded on* B leg* = 3050 + 77(*private port)* = *3127*. 4. Video RTP received on *B leg* = *6402* but forwarded on *A leg* = *6252*. I have also attached here the screenshot of RTP streams from wireshark. This RTP Loss is causing video call quality very bad if network is not too good.Kindly help me to improve the video call quality and reduce RTP loss. Questions: 1. Why some of the RTP packets are being forwarded to private ports? 2. Why there is so much difference in the RTP packets received on the Freeswitch and sent out from the Freeswitch Kindly let me know if i am doing something wrong.

Verto
by Rick Jarvis 19 Sep '17

19 Sep '17

Looking to get into Verto, in particular handling voice calls with JS. Going through the source, I’m wondering: 1. What’s the difference between the Verto source and the Verto Communicator source? 2. What’s the best way to start from the bottom up - by this I mean that it seems hugely comprehensive, but rather than just use grunt to set it all up, I’d like to start simply with the basics… is there for instance a list of the bare minimum scripts / file structure to use? Apologies if this is a silly question, I’m still relatively new to JS and I don’t want to blow my mind in one go ;) Rick
