Carrier-Grade
VoIP Interconnect
Direct IP peering, prefix-based routing control, and SIP architecture built for telecom carriers who demand stability, performance, and full operational transparency.
Interconnect Architecture
SIP RFC 3261 Compliant
UDP / TCP / TLS transport. Port 5060 (UDP/TCP) • 5061 (TLS). IP Whitelist + SIP Digest authentication. NAT traversal via STUN/ICE.
Media & Codec Policy
RTP range 10000–20000 UDP. DTMF via RFC 2833. G.711 PCMU/PCMA (recommended for IPRN), G.729 (compressed), G.722 (HD voice) — codec policy enforced at interconnect level.
Platform & Uptime
VOS3000 + ViciDial on dedicated physical servers. 99.9% carrier-grade uptime SLA. 24/7 NOC coverage with fast escalation and real-time CDR reporting.
Security & Access Control
Strict IP whitelisting per partner, no open SIP registration. Firewall-level SIP filtering, rate limiting on INVITE attempts, and continuous anomaly monitoring.
