With activity increasing on using Asterisk to interconnect to core TDM networks, Convergence is going to be performing SS7 options analysis and reporting on the performance and pros and cons of each option. Initially, we’re going to test libss7 from Digium, chan_ss7 from Sifira and Sangoma’s Signalling Media Gateway.
The questions asked are:
- Can a simple p4 3 ghz based asterisk box handle 4E1 of ss7 signaled calls?
- Can it do the same number of SIP + SS7 calls (signaling and media gateway)
- Whats needed for 8E1? 16E1?
- Whats the load increase for 10cps? 20? 30?
- How much CPU load is utilized in this? Interrupts? Context switches? RAM?
- Which of the three channel drivers handle it best? By how much?
We intend to use 2 identical hw machines. Test bed will be a Gentoo 2008.0 Linux distribution, latest stable kernel (2.6.25). Normalization / Control tests will be SIP-SIP and IAX-IAX calls between the two servers.
Next, we’ll also normalize the TDM drivers, by testing ISDN PRI. For all HW related tests, three sets will be conducted (Sangoma – Sangoma), (Sangoma – Digium) and (Digium – Digium). We intend to use the latest software and drivers available for each component, so that the tests have the longest relevance, shelf-life.
The second phase is to perform homogenous tests (SMG – SMG), (chan_ss7 – chan_ss7), (libss7 – libss7). The third phase will test SMG, chan_ss7 and libss7 in heteregenous environments.
The performance metrics we’re currently looking at are cpu utilization, ram utilization, context switches, interrupts, call setup / teardown time.

Pawel of halo-kwadarat fame, has also done an analysis for SMG on 16E1, read his great analysis and testing methodology.

Could only rustle up a 1.8ghz and a 2.4 ghz dell, will redo the tests later on once same spec servers are available
