Trusted by operators who measure every ASR point.
Call centers, BPOs, resellers and carrier partners rely on DialSync for compliant routes, clean CDRs and responsive NOC support.
We migrated roughly 40M monthly minutes to DialSync last quarter. ASR improved 12 points on our US outbound campaigns, and their NOC flagged a carrier congestion issue at 2am before our ops team noticed anything on our dashboards.
Onboarding took less than 48 hours from KYC approval. CDR delivery via SFTP is consistent — no more chasing missing call records at month-end. The billing portal reconciles with our internal usage within a fraction of a percent.
We run VICIdial on DialSync's hosted platform with their SIP trunking. Route quality on our outbound campaigns held steady through Q4, and STIR/SHAKEN A-level attestation cut our "call failed" complaints noticeably.
As a telecom reseller we need transparent rate sheets and dependable white-label support. DialSync gives us both — our downstream clients get NOC escalation through us, and the margin structure is clear enough to quote confidently on 50M+ minute deals.
UK TPS filtering was non-negotiable for our consumer campaigns. DialSync's OFCOM-aligned routing with built-in TPS/CTPS screening let us pass compliance review with our enterprise clients without bolting on a third-party scrubber.
We interconnect as a carrier partner on selective routes. Interconnect setup was clean, RTP quality metrics are visible in real time, and when we had a routing issue their engineering team had a fix deployed in under four hours.
