asterisk users - May 2009 - Bandwidth management and ADSL router

Hi All;

I discover that most of the voice cutting complain are coming from the Internet
bandwidth when we are connecting two remote offices togethor via Asterisk or any
other IP PBX.

Anyone has an idea on a ADSL router that work as ADSL + Bandwidth division? So
we can resolve the problem of providing a guaranteed bandwidth for the voice
packets instead of suffering the voice cutting?

Regards
Bilal

A lot of the ADSL CPE (customer premise equipment) deployed has basic 
QoS capabilities in a pre-set kind of way, but if you want to do your 
own DiffServ tagging the standard practice is to do Layer 2 Ethernet 
bridging to a more intelligent box behind the ADSL CPE.

m0n0wall and pfsense both do traffic shaping, which forcibly allocates
bandwidth for your VoIP traffic.

Draytek 2800 series routers have adequate traffic management on outgoing 
traffic to do a reasonable job. (There is a very little you can do to 
shape incoming traffic)

However you need to make sure that the actual Internet connection isn't 
where the bottleneck is. Try making calls when you can guarantee that no 
other traffic is flowing into/out of each end.

Thanks for all.

But what all gave me was a software need to be installed on PC, but I am looking
for a router (ADSL router) that can does this, because usually the ADSL router
is the default gateway where all the traffic goes out and in.

Any ADSL router device can do this?

About Draytek, as I understand that control can be done only at upload traffic
and not download traffic, while 90% of the problem are coming from download
traffic, so this is not the needed.

Any advise in that direction?

Bilal

I've had good luck using a sangoma S518 ADSL card in a linux box.  the
logging capabilities are supurb (cought my provider not providing what they
said they were and great for troubleshooting as it logs line speed and
dropouts to the second).  support is also top notch.  once installed it
looks to the system like any other interface.  Since it looks to the system
like any other interface you have the full power of routing, bridging,
firewalling, iptables, neumerous queing schemes, etc.  everything linux has
to offer.  It has served me well and is extremely flexable.

Internal ADSL cards;  not external router appliances.
