Forrester Consulting estimates a 401% ROI for a typical large organization that deploys a centralized SIP trunking topology using Acme Packet E-SBCs. The Total Economic Impact of Acme Packet’s Session Border Controller, which is based on separate and independent research by Forrester, indicates organizations save by eliminating underutilized TDM trunks serving each location as well as lower per-minute rates that apply to VoIP usage. In fact, each of the customers that Forrester interviewed reported a 40%-60% reduction in monthly service fees upon replacing T1/E1 TDM trunk lines with SIP trunks. Obviously, savings is directly proportional to the number of TDM trunks eliminated.

VoIPmonitor is open source network packet sniffer with commercial frontend for SIP RTP and RTCP VoIP protocols running on linux. VoIPmonitor is designed to analyze quality of VoIP call based on network parameters – delay variation and packet loss according to ITU-T G.107 E-model which predicts quality on MOS scale.

You might want to be careful about this after reading this article on slashdot:
The hidden messages can consist of text, audio or video, and can be transmitted at a rate of almost 1 kilobit per second. And, according to Mazurczyk, the secret data is indistinguishable from silence-period traffic
via Hiding secret messages in Skype silences.
That’s about 128 bytes per second or a little less than a tweet or long text per second.
The NTCA wants the FCC to include intercarrier compensation — that’s the sharing of revenues for completing voice calls — in the IP transition so that VoIP calls are treated differently.

Configure Linux to Work with Skype
I’ll assume that because you’re a Linux Journal reader, getting Fedora Core 3 up and running on your Skype server is a no-brainer. The only important thing to remember is that Skype is a Qt application (though it’s also available in a version with Qt statically linked), and the Skype API uses D-BUS. Also, disable the screensaver (after all, there won’t be any screen to “save”) and power standby features as these may interfere with Skype.
Here’s a step-by-step guide to setting up Linux to work with Skype (it assumes you have set up a Linux user account named skype for the purpose):
