[asterisk-biz] New CSRP release: Class 4 / LCR system

[Alex Balashov]

Hello,

On behalf of Evariste Systems, I am pleased to announce a new release of 
our CSRP platform.

CSRP is a Kamailio and PostgreSQL-based LCR (Least Cost Routing), 
accounting and real-time rating platform designed for ITSPs who provide 
PSTN origination and termination.  It incorporates three pillars:

1) Business-layer functionality, such as sophisticated LCR capabilities 
(including profit-margin protection), LNP (local number portability) dip 
support, external CNAM delivery support, real-time rating of CDRs (both 
retail rating and vendor costing), concurrent channel limiting, and 
prepaid credit.

2) Some SBC-like technical capabilities needed to manage a variety of 
PBX endpoints, such as far-end NAT traversal + optional RTP relay, as 
well as an integrated SIP registrar.

3) A strong engineering emphasis on high performance and throughput, 
making the product suitable for high-volume environments such as dialers 
and call center / lead generation routing.  Many of CSRP's technical 
characteristics were shaped by the requirements of extremely high-volume 
dialers who needed an intelligent business layer without sacrificing 
high performance.

Simply put, CSRP is a feature-rich, high-performance, affordably priced 
SIP trunking box.

Traditional mainstays of CSRP include:

- High-performance least cost routing (can handle fast lookups on 
hundreds of millions of prefixes).
- Profit margin protection in LCR.
- Flexible LCR (multiple vendor termination group support).
- Flexible termination rating (multiple rate plan support).
- Support for intra/inter-jurisdictional rating (for interstate and 
intrastate rates or similar, can also be used to craft "unlimited" local 
calling areas).
- Asynchronous LNP dip support (via SIP redirect).
- Concurrent channel limits.
- Real-time call accounting and rating, for both retail and vendor costs.
- Static IP and registration support, and fast failover among customer 
gateways on inbound calls.
- Far-end NAT traversal and media relay support.

Some new features in this release, especially geared for better 
accommodation of retail SIP trunking offerings (an improvement over 
CSRP's largely wholesale heritage):

- An all-new administration GUI.
- A new JSON API.
- Improved vendor deck import capabilities.
- A robust caching layer for LNP and CNAM values.
- Support for delivery of external, asynchronous CNAM on origination 
(via SIP redirect).
- Minute package support.
- Fixed and variable surcharge support (USF taxation ready).
- PSTN call forwarding via integrated B2BUA.
- Voicemail backup.
- Improved route performance data collection and reporting.
