Carrier-grade SIP trunking
Connect your PBXs, carriers and applications with secure, scalable SIP trunks. IP or registration authentication, codec control, channel and CPS limits, CLI/DID manipulation and built-in failover—all managed from one portal.
Connect a trunk in minutes
Point your PBX or carrier at our SIP edge, choose how you authenticate and set your limits. The same trunk works for inbound DID delivery and outbound termination—no separate accounts to juggle.
Total control over every trunk
Authentication, capacity, routing and media—all tuned for wholesale and enterprise traffic alike.
IP & registration auth
Authenticate trunks by static IP ACL for fixed gateways, or by SIP registration with credentials for roaming endpoints.
Channel & CPS limits
Set concurrent-channel ceilings and calls-per-second caps per trunk to guarantee capacity and stop traffic spikes.
CLI/DID manipulation
Rewrite caller ID, normalise to E.164, apply prefixes and translate DIDs with per-trunk number manipulation rules.
Codec support & transcoding
G.711, G.729 and Opus with on-the-fly transcoding so mismatched endpoints always interconnect cleanly.
Secure SIP (TLS) & SRTP
Encrypt signalling with SIP over TLS and protect the media path end to end with SRTP on every trunk.
Failover & redundancy
Geo-redundant SIP edges with automatic re-routing on outage, so a single point of failure never drops your calls.
Bring your own carrier (BYOC)
Plug in your existing upstream carriers and rate plans, or route over ours—mix and match per destination.
Burst capacity & scaling
Scale channels on demand for campaigns and seasonal peaks, then scale back down—no hardware to provision.
Numbers on the same platform as your trunks
Source, provision and route DIDs from the same console—then point them straight at the trunks above. The full number lifecycle, from acquisition to inbound delivery.
Number inventory
Search, reserve and manage local, national, mobile and toll-free DIDs from a searchable real-time stock.
Automated provisioning
Order a number via UI or API and have it active, rated and routed in seconds—no manual carrier tickets.
Porting / LNP
Bring existing numbers across with managed local number portability, status tracking and zero-downtime cutover.
Inbound routing
Map each DID to an account, trunk, IVR, queue or failover target with time-of-day and priority rules.
Global coverage
Numbers in 60+ countries—geographic, national and toll-free—sourced through vetted carrier partners.
Emergency / E911
Register service addresses for emergency calling and stay compliant with E911 and local equivalents.
CNAM & caller ID
Set outbound caller ID per number and manage CNAM display names so your calls are recognised, not blocked.
Number masking & privacy
Anonymise both parties with temporary proxy numbers for marketplaces, ride-hailing and field teams.
Secure and fraud-protected by default
Every trunk ships with encryption, access control and real-time fraud limits—not as paid add-ons, but as the baseline.
Trunks terminate on a Kamailio SBC edge with RTPengine handling media, transcoding and SRTP—open source, no proprietary lock-in.
