[asterisk-biz] "Class 4" SIP trunking / LCR platform

[Alex Balashov]

It's hard to say for sure because:

1. Having a proxy-based core, a lot depends on the throughput bottlenecks of the endpoints;

2. The workload is substantially I/O-bound in many respects, though certainly asynchronous where possible. So, hardware is a factor.

However, we have seen throughput of at least 250 CPS.  That's just being realistic; we get a lot of BS CPS requirements from dialer guys that we would find difficult to meet, but which they also don't actually have.

>>

>> When talking here about larger-scale commercial service delivery platforms, the focus is usually on multi-tenant hosted PBX containers and Asterisk-based softswitch assemblies that offer rich Class 5-style subscriber features.  CSRP doesn't try to do any of that; it tries to do one thing and one thing well, and that is to address the needs of wholesale operators, CLECs and ITSPs who provide SIP trunking.  There are plenty of other good solutions routinely advertised here for the small to medium integrated service space, but we feel that CSRP specifically meets the needs of wholesale/resale without compromises in any other direction.
>> 
>> A lot of the technical architecture of CSRP has been influenced by the demanding requirements of customers who run dialer traffic, so there is a very heavy emphasis on high capacity and throughput.
