Good Day Everyone,

I would like to ask if how many channels my server can handle. Here is my server set up:

Server
Dual Xeon 5150, 4 Cores / 4 Threads, 2.66Ghz - 2 processors
8GB DDR2
500GB Hard Drive
20TB Monthly Transfer
OS: OpenSuse 12

Vicidial
VERSION: 2.8-428a
BUILD: 140305-0846
Codecs: ULAW and ALAW
VOIP: apntelecom with 100 channels

I like also to ask on what are the settings to use the maximum channels.

Thanks,

Pejie

Hello Pejie,
Welcome to the community!
The amount of channels that your server can handle depends it depends of:
The codec you are using (G729, g711)
your actual internet speed (20TB Monthly Transfer, but this does not said the speed (down/up)


But you can have an idea of the amount of channels here:

Hello Omar,

Thanks for the reply.
Here is our internet speed:
Download: 74.53 Mbits/s
Upload: 13.62 Mbits/s

We are only using ULAW and ALAW codecs. We dont have license yet for g729 codec.

Thanks

Hello,
For Voip the better is to have symmetric Bandwith (same upload as download), because if not, your limit is defined by the lowest.
In your case 13.62 Mbits/s
For calculation, take this in consideration:

You have available 1.70 MB/s that will be used not only for Voice, but also for data transfer(web, data base, etc)
Lets said that you will have 80% available for Voip 13.62 *0.8 => 10.88 MB/s
G711 Needs at least 64 Kb/s

10880 KBs/ 64 KBs = 170 Channels
