Wholesale IP Interconnection
Carrier-to-carrier SIP interconnection for packet-based voice at scale.
Wholesale IP Interconnection
Wholesale IP interconnection, transport and call completion of packet-based voice traffic. We interconnect with international carriers over secure SIP trunks, providing bilateral and unilateral traffic exchange with carrier-grade session border control.
Key capabilities
- Secure SIP trunking with session border controllers
- Bilateral and unilateral traffic models
- IP whitelisting, TLS/SRTP and IPsec options
- Elastic capacity — scale concurrent channels on demand
- Multi-protocol interworking (SIP ↔ SIP-I ↔ ISUP)
- Detailed CDR exchange and reconciliation
Why carriers choose it
Lower cost per minute
IP-native interconnection removes legacy transport overhead.
Fast provisioning
New capacity can be turned up without physical circuit lead times.
Secure by design
Topology hiding, access control and encryption protect both networks.
