3CX SIP Trunking

SIP trunking replaces traditional ISDN and analogue phone lines with voice-over-IP connections that route calls over the internet. 3CX SIP Trunking from Xcobean delivers carrier-grade voice connectivity with significant cost savings — typically 40-60% less than legacy PSTN lines — while providing far greater flexibility and scalability. Adding new channels takes minutes instead of the weeks required to provision physical lines.

Xcobean maintains direct peering with major Kenyan and East African carriers, ensuring low-latency call routing with local number portability. Businesses can retain their existing phone numbers while migrating to SIP, and we support geographic numbers across multiple African countries including Kenya (+254), Uganda (+256), Tanzania (+255), Rwanda (+250), and South Africa (+27). For international calling, our global SIP trunk partners deliver competitive per-minute rates to over 200 destinations.

Every SIP trunk deployment includes automatic failover to backup routes, ensuring continuity even if a primary carrier experiences an outage. Call quality is monitored in real time using MOS scoring, and our NOC team proactively investigates any degradation. TLS encryption and SRTP secure all signalling and media, protecting sensitive voice communications from eavesdropping.

Whether you are connecting a 3CX PBX, FreeSWITCH, Asterisk, or any standards-compliant SIP endpoint, Xcobean provides pre-configured trunk templates and dedicated onboarding support to get you connected quickly and reliably.
