[Asterisk-biz] Minimum internet connection!

[Alen Miketic]

It was absolutely coincidental that my question came just after this one.  Has anyone verified these IAX2 trunking figures?  25 channels in a 384 pipe doesn't seem right.  Plus, does trunking work, or is there currently a bug with it?

According to that link, 25 channels of G729 is 600k. 16 G729 channels
theoretically fit in 384kbps of IP traffic. Also note that this is
symmetrical (you need the same bandwidth upstream and downstream).

Now, with IAX2 trunking you could get 25 channels in 384kbps:

Hi, 
 
A good start would be:

depending on the codec 384 kbit should be enough (g729 codec).
You can lower the bandwidth by using some low bitrate codec or 
gateways like Quintum that have PacketSaver techniques).
 
We have some ADSL gateways running heavy traffic (20 calls), 
it really depends on your ADSL provider quality and the router
behind this connection.
 
Kind Regards, 
Dario.

Hi,
What is the minimum internet connection needed to run asterisk, would an
ADSL be suffecient, and if yes how many internet connection needed to run 25
concurent calls.
Thanks.
MOK.
