Hey guys

We have a VoIP solution set up in our offices, being in South Africa our maximum line speed is 4mb which is really limited, so anything above 4 calls at a time could get a little much for the line.

I have a spare ADSL line that I want to set up some sort of load balancing on. I just want to know if its possible to set up a Linux box with 2 NIC's to load balance the calls on both lines so we can get a few more calls out at a time. What software could I use to set something like that up?

Thanks

Hi, welcome to LQ!

You're not saying much about your infrastructure ... have
you come across http://www.kamailio.org in your searches?
It has load-balancing as a built-in feature.

Hi there.
Here is something I found at LinuxQuestions

Hope this helps.

@ Tinkster, sorry for lack of info, to be honest, there isn't much info, as this is a brand new network, which was set up on monday, the VoIP is on its own line and on its own network, so its just straight out to the cloud, that is why I want to throw in a box to balance between 2 connections to the cloud.

Kamailo looks like a good option at the moment (thanks) Will read a bit about it and see if it will suffice.

@ OdinnBurkni, yea I found that thread, at 1st glance I thought it wouldn't apply to me, as he is trying to get load balancing to a switch, and I am trying to get load balancing to 2 routers, but now it is looking like the same thing.

Im sure this is enough info to get me going, thanks a lot guys

One more question: Would it be a better solution buying one of these? http://www.xincom.com/products/502/overview.php

Or could I achieve the same thing with linux? I already have a spare PC and line and router, so there would be no cost in going the software route.

Hi.
I don't think you can say this solution is better than the other.
If you have a spare pc and line and everything and time to work on this then I would suggest you try Linux first. You would at least expand your knowledge...
If you don't have the time to do the experiments then I think you would be better of buying this router, it looks like it does all you want.

I found these on another forum:
LINKSYS RV042
XINCOM XC-DPG502
EDIMAX BR-624
D-Link DI-LB604

One of them is the one you found. Here is a link to the forum I found: DSLreports.com
I found more...

Decided to go with the manual set up, I have some time to work on it, busy downloading the latest SUSE and gonna get going.

Again thanks for the help guys, its much appreciated, im sure I will be back with new questions soon

Hi.
How is it going? Is it setup already and working? Please post your results and how you did it (if it worked... ...and even if it didn't work), it might help others...
