Monitoring audio quality
Hi Guys, I have a prety large system with a lot of traffic. Sometimes I get complains from customers about 'loud noises', 'not hearing audio', or just 'bad quality audio'. I can see a lot of info on the CDR's, no I have tried to search the wiki and groups for some explanaition about how to interpret them, but there is not much to find.. Is there someone who can tell me what these mean, and how to interpret them, could they help me in finding issues with audio? <rtp_audio_in_raw_bytes>573964</rtp_audio_in_raw_bytes> <rtp_audio_in_media_bytes>572932</rtp_audio_in_media_bytes> <rtp_audio_in_packet_count>3337</rtp_audio_in_packet_count> <rtp_audio_in_media_packet_count>3331</rtp_audio_in_media_packet_count> <rtp_audio_in_skip_packet_count>47</rtp_audio_in_skip_packet_count> <rtp_audio_in_jb_packet_count>0</rtp_audio_in_jb_packet_count> <rtp_audio_in_dtmf_packet_count>0</rtp_audio_in_dtmf_packet_count> <rtp_audio_in_cng_packet_count>0</rtp_audio_in_cng_packet_count> <rtp_audio_in_flush_packet_count>6</rtp_audio_in_flush_packet_count> <rtp_audio_in_largest_jb_size>0</rtp_audio_in_largest_jb_size> <rtp_audio_out_raw_bytes>485556</rtp_audio_out_raw_bytes> <rtp_audio_out_media_bytes>485556</rtp_audio_out_media_bytes> <rtp_audio_out_packet_count>2823</rtp_audio_out_packet_count> <rtp_audio_out_media_packet_count>2823</rtp_audio_out_media_packet_count> <rtp_audio_out_skip_packet_count>0</rtp_audio_out_skip_packet_count> <rtp_audio_out_dtmf_packet_count>0</rtp_audio_out_dtmf_packet_count> <rtp_audio_out_cng_packet_count>0</rtp_audio_out_cng_packet_count> <rtp_audio_rtcp_packet_count>0</rtp_audio_rtcp_packet_count> <rtp_audio_rtcp_octet_count>0</rtp_audio_rtcp_octet_count> Or are there other (better) methods of finding problems related to bad audio?

Hi Michael, Not exactly an answer to your question, but I have quite a lot of call traffic running over three servers. I have found the best way to manage this is by using a monitoring tool. The one I use is http://www.voipmonitor.org/, the actual daemon is open source but you can buy a webUI which uses rrdtool to graph the call quality and display the calls history. Using a tool like this you can get an idea of call quality for each call. Cheers, Ash. On 31/05/2012, at 7:19 PM, Michael Lutz wrote:

Hi Mike, If you are interested to achieve real-time improving of the quality (as opposed to passive monitoring) you can try PBXMate. This tool is *NOT* a passive monitoring tool but an active tool. It works like a Sip Proxy and if it encounters a quality issue during a call (e.g. noise and/or low volume) it will fix it in real-time. As a by product the PBXMate also provides statistics on the quality. You can see one option for integration in the wiki http://wiki.freeswitch.org/wiki/PBXMate-FreeSWITCH-integration Cheers, ________________________________ From: Ash <ash@archerdrive.com> To: FreeSWITCH Users Help <freeswitch-users@lists.freeswitch.org> Sent: Thursday, May 31, 2012 12:30 PM Subject: Re: [Freeswitch-users] Monitoring audio quality Hi Michael, Not exactly an answer to your question, but I have quite a lot of call traffic running over three servers.

Hi all, I like to plan a opensourceproject. Open_voicechat is the first open source voice chat worldwide. Freeswitch and other voip-systems don.t have a big application. Unfortunately, I can not even work, programming. I am looking for people to help me, and dominate one of the following programming languages: perl lua java php python or ruby. There is no specific programming language requested. I have setup a big mysql database for all modular features of a nice chat. Mailboxes, news forums, line managment and more! An exact documented functionplan has already been added. A german demo voicefile has ben included to the archive. You can download my long work at: http://www.blindi.net/downloads/open_vocechat.tar.gz I have 2 Languages german and english added to the archive. I would be happy if someone help me. The advantage of FreeSWITCH is the flexibility.

What kind of voice chat are we talking about? There are plenty of voice chat type things out there (skype for one). Specify your demographic and what the actual purpose is, and how it's going to be different from any other provider. -BDF On Mon 04 Jun 2012 11:27:54 AM EDT, Thomas Hoellriegel wrote:

Hi Brian,
What kind of voice chat are we talking about? There are plenty of voice chat type things out there (skype for one).
This is a Freeswitch-interface. This chat can be setup as a sipbased Freeswitch. Skype is proprietary and not opensource. You can.t setup skype to a simpli root server on textbase only system.
Specify your demographic
Sorry, i.m. blind. grafic???? in a voicechat?? I don.t understand! Skype is not operable on simple text based systems. the installation of freeswitch on skype is very difficult. --------------- Du kannst mich jederzeit kostenlos per Festnetz erreichen unter: http://www.blindi.net/callback homepage: http://www.blindi.net blinde-misc mailingliste für blinde. anmeldung unter: http://www.blindi.net/mailman/listinfo/blinde-misc
baresip is a console-based open source SIP client. http://www.creytiv.com/baresip.html The documentation could be better, but it's text-based (assume that running in the console or terminal is what you meant by text-based).

I don't understand what you are trying to accomplish. You said you were blind, which is why it should be text based, but what exactly are you trying to accomplish?

Hi Brain,
I don't understand what you are trying to accomplish. You said you were blind, which is why it should be text based, but what exactly are you trying to accomplish?
ou meant something of a graphics demo. I can.t look any grafics.
Mmy intention is: I like to create a Unified Messaging chat. Since there are many blind people, they rely on language. One can make with the help of these forums people information easily accessible. Since the functions I have a very well thought out, you could also use this system well in the bussiness areas. I downloaded your files but that doesn't tell me much. I means i have a idea, but i.m. not a programmer. I have setup the database, and i documented the features to progamm a professional voicechat for free. Sip is open and very flexible.

Hi Thomas, I appreciate your effort in communicating here and in trying to make something the helps other blind and visually-impaired users. When Brian Foster asked about "demographics" he was using an English word that really means "target audience" or something like that. ( www.freetranslation.com translates it into German as "Demografisch" if that helps.) What he was asking is, "Who would use the software that you are wanting to build?" You've already answered part of that question: people who use screen readers and need a text-based setup. I believe another person mentioned Baresip in this email thread. If you haven't checked that out you might want to. It could give you some ideas on how to proceed. Thanks, Michael On Mon, Jun 4, 2012 at 12:33 PM, Thomas Hoellriegel <admin@blindi.net>wrote:

Hi Sanath Thanks for your helpfull message I suggest: we do everything step by step. First: the voice mail creation and login. for example: press 1 for login. Press 2 to create your onw mailbox. It is important that the mailbox already exists. If the Mailbox exists, play a error wavfile for example: Sorry this mailbox is allready exists, and go back to the creation option again. Thanks. --------------- Du kannst mich jederzeit kostenlos per Festnetz erreichen unter: http://www.blindi.net/callback homepage: http://www.blindi.net blinde-misc mailingliste für blinde. anmeldung unter: http://www.blindi.net/mailman/listinfo/blinde-misc
