Voice Bandwith

[lordhyde]

Hi,

I'd like your advice.

I have a server with GoAutoDial and 5 pc's with eyebeam as softphone,
My server is a Sempron 2500 with 2gb in ram.
My internet connection is 5mbps

But when 2 or 3 pc's try to call at the same time, the voice gets very noisy and you can't understand the person you're calling. (I don't know the exact word to name the problem, but it's like you hear some words and you lose other words)

What can be the problem?
The server? the internet? the voip provider? a very high voice quality?


In case it were the voice quality.... how can I setup a lower voice quality? I can't find where to configure the audio codecs

every answer will be helpful

Thank you

1) Always post your installer with Version (goautodial is the installer, which version?)

2) Always list your Vicidial Version with Build

3) I'll assume you are using VOIP ... please list the Protocol (SIP/IAX?) and codec (ulaw/gsm/g729?) in use

4) Are calls internally also choppy or only outbound?

5) DO try another provider (NEVER limit yourself to only one provider, you should always have at least TWO and preferably three, if people's weekly paycheck is riding on THIS machine)

6) What exactly is your server load? (listed under Admin->Servers for this specific server; also give us the number of simultaneous calls, easiest method is "show channels" from within asterisk)

1) Always post your installer with Version (goautodial is the installer, which version?)
VERSION: 2.2.1-237
BUILD: 100510-2015

2) Always list your Vicidial Version with Build

3) I'll assume you are using VOIP ... please list the Protocol (SIP/IAX?) and codec (ulaw/gsm/g729?) in use
Protocol SIP
Codec: the eyeBeam has active 8 codecs, and 5 codecs inactive, I don't know which I should deactivate or activate
Disabled: BroadVoice-32 FEC // G711 aLaw // iLBC // L16 PCM Wideband // Speex
Enabled: BroadVoice-32 // DVI4 // DVI4 Wideband // G711 uLaw // G729 // GSM // Speex FEC // Speex Wideband // Speex Wideband FEC



4) Are calls internally also choppy or only outbound?
I've just discovered how to make the internal calls
but they sound good, just the outbound are choppy

5) DO try another provider (NEVER limit yourself to only one provider, you should always have at least TWO and preferably three, if people's weekly paycheck is riding on THIS machine)
I have 5 active carriers.
they're directed to 3 different providers.
what i don't know, is if the server selects automatically the best, or I need to select wich one to use, or what I should do in that case.

6) What exactly is your server load? (listed under Admin->Servers for this specific server; also give us the number of simultaneous calls, easiest method is "show channels" from within asterisk)
System Load: 13 - 5%
Live Channels: 2
Disk Usage: 1 - 3% 2 - 18% 3 - 0%

It seems to be everything working fine, but I don't know what else to do.

Thanks for your help[/b]

THAT is the Vicidial Version. NOT the GoAutoDial Version. Vicidial is the PREDICTIVE AUTODIALER. GoAutoDial is the INSTALLER. I was requesting the version of the installer (helps to track installer bugs and bring others with the same installer version to THIS post). the Installer version will be contained in the name of the .iso image you downloaded.

2) Always list your Vicidial Version with Build

Handled!

Enabled: BroadVoice-32 // DVI4 // DVI4 Wideband // G711 uLaw // G729 // GSM // Speex FEC // Speex Wideband // Speex Wideband FEC

I didn't ask which ones are "active" or "enabled". I asked which ones where in use during the call.

Code: Select all

asterisk -rx "sip show channels"

But that was a good reflex, because obviously watching the active codec and altering them to see if there is any effect on call quality is a method of troubleshooting.

Be SURE that you have NOTHING ELSE in the office accessing your internet (only Vicidial). No "YouTube", no Facebook, no "Mediaplayer radios". NOTHING. JUST Vicidial.

5) DO try another provider (NEVER limit yourself to only one provider, you should always have at least TWO and preferably three, if people's weekly paycheck is riding on THIS machine)

Your campaign decides which carrier to use. If you do not know which one(s) you are using ... you need some training!! The method above used to show the channels will show the IP address with which the call is connected in addition to the codec. If you are connecting all your calls to the same IP ... you'll need to modify your campaigns to call through different providers! (Dial prefix compared to the dial plan first digit under admin->carriers)

2 live channels? 5%? and you had crappy sound already? Hm.

so far we do not know that you are not just calling through a single bad provider.

also: surf to "speakeasy.net" and use their speed test when noone else is on the system (so you get the "total" speed available,not just the leftover). If you're in the US: broadband.gov is a great place to do this (the FCC collects statistics on carrier speeds so they can force carriers to INCREASE their speed )

i had a long time bad quality of voice !

i have changed the settings in eyebeam:

1) i use only g729 to call the server (for a low bandwith in my office)

2) the most of my agents had a very bad quality, the only way i have found is:

go to eyebeam options-devices and disable all AEC/ AGC/ and noice reductions.

after that changes all of my agents have a wonderfull quality
