Tinkering with modified WRT54G firmware

A fairly common VoIP complaint (depending on configuration) has been choppy communications when users are throttling their broadband connection. To that end, users are tinkering with modified router firmware upgrades to incorporate bandwidth management and a host of other free improvements. This thread in our VoIP forum outlines how one user obtained the quality of service he was looking for with a Linksys WRT54G and Linux based modified firmware from Sveasoft.

The modified firmware has incorporated Wondershaper bandwidth management, allowing users to avoid choppy conversations while gobbling up bandwidth with other applications. Of course that doesn't just apply to VoIP, the firmware allows you to prioritize any important traffic across your network.

The improvements don't end there either, as the firmware also incorporates a number of networking improvements and upgrades, boosts power levels, and adds quite a number of treats to the router's web-interface.

A list of all the features added to the Sveasoft Linksys build is here. Discussion over at the Sveasoft forums tackles what kind of additional functionality users would like to see (such as which VPN software customers most prefer). You can download the firmware here at the Svesoft website, then find detailed instructions on getting up and running here in our forums.

Sveasoft isn't alone in offering modified firmware; there's also the Wi-Fi Box firmware that users in our Linksys forum have been discussing for the past month. It's an impressive way to get quite a bit of added functionality out of a piece of sub-$100 hardware ($80 at Amazon).

Although the Cisco alert should draw the attention of CIOs, and justifiably so, it is important to keep in mind that threats to VoIP systems still are fairly rare, according to Gartner analyst John Pescatore.

How to Distribute VoIP Throughout a Home

One obstacle to replacing traditional phone service with Voice over IP is that for your existing home phone jacks to work, it's necessary to make a change to your inside telephone wiring.

Fortunately, this change is very easy to make. In some cases it's as simple as removing a plug from a jack. Still, a basic understanding of how telephone wiring works is useful before attempting to make such a switch.
