Hello, Evariste Systems announce with pleasure the newest major release of the Canonical SIP Routing Platform (CSRP), a SIP trunking service delivery platform based on Kamailio and PostgreSQL. CSRP combines a high-performance Least Cost Routing engine with a sophisticated and flexible business layer to provide an advanced "Class 4" solution for origination and termination routing, rating and accounting to the ITSP industry. It is used by a range of SIP operators, from conversational SIP trunking providers to wholesale termination companies specialising in high-volume traffic, as well as application providers such as call broadcasters and hosted IVR companies. The v0.3 release provides many long-awaited improvements, including: - An improved CPS (Calls Per Second) rate-limiting mechanism. - Pseudo-asynchronous call processing for improved CPS performance and throughput. - Global termination ANI blacklist. - PDD-sensitive failover across termination vendor routes. - Redis-based LRN and CNAM dip caching (to replace Memcached). - Full topology hiding support. - Integration of optional outboard SBC/B2BUA component. - Many API and GUI improvements in functionality and usability, including better online help and navigation. - Signalling-based dead peer detection/keepalive support. At Evariste, we take pride in our established reputation for high-value vendor support and deep technical expertise. Moreover, we offer CSRP at a flat licence fee irrespective of number of channels, calls, hosts, ports, etc. If you are interested in learning more about CSRP, please direct enquiries to sales@evaristesys.com or give us a call at +1-678-954-0670. -- Alex Balashov - Principal Evariste Systems LLC 235 E Ponce de Leon Ave Suite 106 Decatur, GA 30030 United States Tel: +1-678-954-0670 Web: http://www.evaristesys.com/
