Configuration FlexibilityAll-in-one: Signaling + media, SIP, H.323 |
Access Control ListsCPS/RPS restrictions across IP networks and by registered/static gateways. |
Session Control FunctionalityB2BUA |
Topology HidingOn signaling and media layer, NAT by means of OS |
Media TranscodingG.729 (plain, A,B, AB), G.723.1, G.711A-Law, G.711 mU-Law, G.726, Speex, AMR NB, iLBC, GSM FR – transcoding;H.261, H.263, H.264 – pass through; Point-to-point media capability. Configurable proxy policies (no proxying, without codec conversion etc.) |
Routing IntelligenceIncoming and outgoing call number, origination equipment, time-of-day/days-of-week/month, dial-peer priority/ statistics (QoS, ASR, etc.), incoming SIP 300/302 redirect messages, LRQ, relative/absolute gateway workload, codecs, CPC, other call parameters. |
Load BalancingUsing hunt, round-robin, least busy, proportional distribution or least-busy balancing methods, statistics-based balancing (ASR-, QoS-oriented, etc.) |
Service AssuranceQoS measurement (packet loss, latency, and jitter), real-time failure notification, EMS, QoS marking, load balancing, redundancy deployments, ingress traffic restriction by CPS |
Calls Per Second/BHCA500 CPS per traffic entry point, multiple entry points, BHCA 10 mln. |
Call/Session Admission ControlRestrictions by CPS, RPS, CC, registered/static gateway |
Concurrent Calls50 000 per cluster |
Scalability Using Multiple SystemsNear-linear scalability by adding servers and entry points due to modular architecture |
Call Detail RecordsCDRs in the DB, interim CDR reports, statistics keeping, schedule-based CDR import and export (to ftp, etc.) |
High Availability/RedundancyCluster system with the capability of entry point shifting among the cluster servers and a plurality of entry points, load balancing, “safe configuration” mode |
