FreeSWITCH in virtual environments
by Dan Edwards 02 Feb '16

02 Feb '16

I am reviewing the Confluence Virtualization page and had some questions, in particular about VMWare. My company distributes some of its software as a VMWare image file and we were looking to distribute a new product using FS in the same manner. The products operate at a customer premise, on their VMWare infrastructure, not in a cloud environment. Since our customers already have VMWare, switching to a different VM infrastructure is going to hurt, so I am looking for options/alternatives. First, does anybody know if the virtual timing issues with VMWare have improved since this page was last updated in 2014? Is VMWare still not good enough? Is it possible to throw CPU & memory at this and make VMWare good enough, or is the virtual timing just not workable? On the virtualization page, there was a comment from 2010 that you might be happy with a High CPU Medium instance on AWS EC2. Certainly workload is a factor here, but I am trying to get my head around how big a machine to perform how small a workload. Is there a place where people talk about their experiences? Are there other VM platforms that might be acceptable? Any help or comment is appreciated. Thank you, Dan

Simple LuaScript to Record Session Failing
by Leonardo Lima Ribeiro 01 Feb '16

01 Feb '16

Hello all, I’m trying to record an IVR using my gateway to do the outbound call in my luascript: local new_session = freeswitch.Session("[origination_caller_id_name=‘987654321',origination_caller_id_number=‘987654321']sofia/gateway/MY_GATEWAY/3157244022", session); new_session:execute("record_session","/usr/local/freeswitch/recordings/myrecording.wav") new_session:sleep("10000") new_session:hangup() So in the above script I just call to the Bank Of America as an example and try to record the first 10 seconds of the call in the recordings path. The problem is that I have an empty recording file.. Why? The funny thing is: if I add this command after the record_session command: new_session:streamFile("voicemail/vm-goodbye.wav”); And then this is the entire new script: local new_session = freeswitch.Session("[origination_caller_id_name=‘987654321',origination_caller_id_number=‘987654321']sofia/gateway/MY_GATEWAY/3157244022", session); new_session:execute("record_session","/usr/local/freeswitch/recordings/myrecording.wav”) new_session:streamFile("voicemail/vm-goodbye.wav”); new_session:sleep("10000") new_session:hangup() I can hear the Good Bye sound from my script and then hear the Bank of America IVR. I just don’t understand why the record works if I play a sound in our side and the record does not work if I don’t play any sound. Do you know what’s happening? How can I solve this? Thank you!

[Video Calling Issue][Freeswitch 1.7]
by Bilal Abbasi 01 Feb '16

01 Feb '16

Hi Users, I am writing this question after reading old questions and forums, so my problem is i am unable to dial video call using freeswitch 1.7. I have enabled video codecs in var.xml (VP8,H263,H264) and i am using bria sipfone for UA1 and UA2. I am able to dial the normal call but unable to dial video. do i need any further variables to activate video calling? One of my friend told me to shift to FS 1.6 as that provides transcoding. so can anybody help me out. FS Version: 1.7.0 OS: jessie 8 Softphone: Bria Regards Abbasi

DTMF capture and early media
by Борисов, Дмитрий / Dmitriy Borisov 30 Jan '16

30 Jan '16

Hi, All! https://tools.ietf.org/html/rfc3960 has next part: Early media refers to media (e.g., audio and video) that is exchanged before a particular session is accepted by the called user. Within a dialog, early media occurs from the moment the initial INVITE is sent until the User Agent Server (UAS) generates a final response. It may be unidirectional or bidirectional, and can be generated by the caller, the callee, or both. Typical examples of early media generated by the callee are ringing tone and announcements (e.g., queuing status). Early media generated by the caller typically consists of voice commands or dual tone multi-frequency (DTMF) tones to drive interactive voice response (IVR) systems. But I know that in FreeSWITCH in preanswer state I can`t capture DTMF. Why? This part of RFC is conflicting with some other standard? It can be very intresting feature. -- С уважением, Борисов Дмитрий Отдел облачных технологий 1С-Рарус Тел. +7 (495) 231-20-02 доб.: 15-94 -- with best regards, Dmitriy Borisov 1C-Rarus Cloud Services tel.: +7 (495) 231-20-02 add.: 15-94

Audio Codecs over Mobile Connection
by Oleg Stolyar 30 Jan '16

30 Jan '16

Hi guys, does anyone have experience using different codecs to reduce choppiness and metallic/robotic sound when connecting to FreeSWITCH from a mobile device? I know both OPUS and G.722 have packet loss concealment but I wonder if someone actually has practical experience with different codecs over iffy mobile connections. OPUS vs. G.722 vs G.711

Routing and multicast question
by Chris Mandra 30 Jan '16

30 Jan '16

Hi guys - I have a question: I want an endpoint sending an audio RTP stream to freeswitch, which freeswitch is transcoding and then sending the transcoded RTP stream to another device on my network from which I then want to send back INTO freeswitch before sending to the 2nd endpoint. I’d like the stream from freeswitch to the other device on my network to be a multicast RTP stream. What’s the best way to do this? thanks! chris

Resetting FS call counters
by Kurtis Heimerl 29 Jan '16

29 Jan '16

Hello All, I'd like to gather statistics about call failures. FS already does this for gateways: freeswitch@internal> sofia status external Profile::Gateway-Name Data State Ping Time IB Calls(F/T) OB Calls(F/T) ================================================================================================= NAME::NAME sip:FreeSWITCH@IP_ADDRESS NOREG 0.00 0/0 290/453 ================================================================================================= 1 gateway: *Inbound(Failed/Total): 0/0,Outbound(Failed/Total):290/453* However, this statistic is already aggregated and I'd like it in time series. Is there a way to reset it to zero after a lookup in order to figure out how many calls have happened since the last query?

RingBack for PSTN call
by ankitdoshi 29 Jan '16

29 Jan '16

Hello, I want to set .wav as ringback tone for PSTN call, like caller tune. I have implemented it partially for local calls by getting idea from here, https://wiki.freeswitch.org/wiki/Custom_Ring_Back_Tones i have set the param like this, $xml .="<action application=\"set\" data=\"ringback=/usr/local/freeswitch/sounds/en/us/callie/astpp-menu.wav\"/>"; before bridge line in dialplan. This works with local calls , but when i dial PSTN call then i hear only ring tone and not my set .wav audio. Any suggestions are welcome. Thanks. ----- Thanks Ankit Doshi -- View this message in context: http://freeswitch-users.2379917.n2.nabble.com/RingBack-for-PSTN-call-tp7596… Sent from the freeswitch-users mailing list archive at Nabble.com.

Checking which codecs a SIP-Trunk provides.
by Oivvio Polite 29 Jan '16

29 Jan '16

I've registered with SIP-trunk providers for experimentation. How can I figure out which codecs a SIP-trunk (gateway in FS parlance?) provides? regards, Oivvio Polite
