Call Termination
US voice routes with clean CLI and honest ASR
Terminate outbound voice to any US destination over direct and tier-1 interconnects. We publish real ASR and ACD figures, keep CLI intact where the route permits, and price competitively without quietly degrading quality.
Premium and standard routes
Pick the quality-to-cost profile that fits each destination and campaign.
Caller ID preserved
Your caller ID is passed through intact on every US route, for higher answer rates.
Automatic failover
Least-cost routing reroutes around a degrading carrier in real time.
Overview
How Call Termination works
Cheap minutes are easy to find; cheap minutes that actually connect are not. VoipXDialer maintains a routing table built from direct carrier relationships and selected tier-1 wholesale partners, monitored continuously for answer-seizure ratio, average call duration, post-dial delay and audio quality.
You choose the profile per destination: premium routes where deliverability matters most, or standard routes where cost leads — both preserve your caller ID. Least-cost routing with automatic failover moves traffic off a degrading carrier before your agents notice, and a real-time dashboard plus CDR API keeps your margins visible.

Customer stories
Teams already running this
We moved 140 agents off an on-premise dialer in under three weeks. Talk time per agent went up by roughly 40% in the first month, and we finally stopped losing mornings to hardware faults.
Local DIDs across twenty-two states from one portal, one invoice and one support contact. Our answer rates climbed the moment we switched to matched area codes in each market.
Questions
Call Termination FAQs
Yes, on every route. The caller ID you send is passed through intact, provided it is a number you own or are authorised to present. We do not offer routes that substitute or strip caller ID — that is what gets traffic flagged, and it is prohibited under our acceptable use policy.
Least-cost routing selects the best route for the destination and quality profile you have chosen, then automatically fails over if ASR, PDD or audio quality drops below threshold.
Yes. ASR, ACD, PDD and NER are visible per destination in real time, and full CDRs are available in the dashboard or through the API.
Both prepaid and postpaid are available. Prepaid accounts get real-time balance tracking and configurable low-balance alerts.
Test trunks are typically issued the same day so you can benchmark our routes against your current carrier before committing traffic.
