Voice Routing
Carrier and quality-aware voice routing—LCR patterns, route sets, and failover across interconnects.
Voice routing decides which carrier or path carries a call. We design routing tables, LCR-style policies, quality and priority rules, and failover behavior on softswitch and SIP proxy platforms—so cost, quality, and resilience are explicit policy rather than accidental defaults.

Who it’s for
- • Wholesale and retail voice carriers
- • Aggregators managing many egress routes
- • Platforms needing tenant-aware route policy
Problems we address
- • Routes are updated manually with little audit trail
- • Failover to secondary carriers is untested
- • Quality issues are blamed on “the network” without data
Expected outcomes
- • Structured route sets with ownership and change control
- • Priority/LCR policy matched to your commercial model
- • Monitoring hooks for route health

FAQ
We can implement routing that consumes your rate/priority inputs. Fully automated rate shopping depends on the data feeds and controls you want—scoped explicitly when needed.
