Softtop's CLI Routes page centers on caller ID authenticity as the foundation of trustworthy outbound calling. CLI routes pass the full originating number to every destination, which the page states improves answer rates by up to 40 percent compared to anonymous non-CLI routes — a standard the page frames as something businesses, regulators, and customers all now expect rather than an optional premium feature. A proprietary Least Cost Routing engine evaluates live carrier rates, quality metrics, and destination rules in real time, automatically selecting the cheapest compliant CLI path without sacrificing Answer Seizure Ratio or voice quality, so cost optimization doesn't come at the expense of caller ID integrity. Trust and compliance are built into onboarding through three automated protections: every CLI call is signed with STIR/SHAKEN Level A, blocking spoofed caller IDs at the source; global compliance is enforced through FCC and GDPR readiness with data residency controls and retention policies configured without additional setup; and fraud is blocked in real time through IRSF detection, spoofing blocks, and SIP rate limiting that fire automatically before a fraudulent call can complete. This combination — guaranteed number presentation, automated Least Cost Routing that still respects CLI requirements, and built-in STIR/SHAKEN attestation — targets businesses where the called party needs to see and trust the calling number: enterprise outbound sales and support, financial services and healthcare where regulatory number presentation rules apply, and any operation where answer rates depend on the recipient recognizing or trusting the caller ID. The page targets businesses and carriers that need every outbound call to arrive with a verified, trustworthy caller ID rather than accepting the lower cost and lower answer rates of anonymous non-CLI routing.
