I need a seasoned VoIP/SIP professional who can open reliable wholesale termination routes to Premium-Rate Number (PRTN) destinations worldwide. Voice call routing is the sole focus—no SMS or multimedia at this stage. The immediate goal is to secure stable, high-quality CLI or CC routes that reach the UK, the Caribbean, North America and any other international PRTN markets you can cover. I do not yet have relationships with wholesale SIP carriers, so you would be expected to bring your own interconnects or broker new ones on my behalf, handle the commercial negotiations, and deliver live test traffic that proves the route works at agreed ASR, ACD and PDD benchmarks. You will be working alongside our in-house mobile-security app team; your routes will ultimately feed fraud-detection and call-protect features inside the product, so consistency and uptime matter as much as aggressive rates. Familiarity with common softswitches, SIP signalling, SIP-TLS, RTP-SRTP, and standard fraud-mitigation tools will help us integrate faster. Deliverables (acceptance criteria): • At least one functioning wholesale SIP trunk per target region capable of routing PRTN voice traffic. • Live test results documenting ASR, ACD, PDD and CLI presentation. • Rate sheet and commercial terms for ongoing traffic. • Technical hand-off details (IP, codecs, authentication, fail-over notes) suitable for direct switch integration. If you are confident in your existing carrier portfolio and can activate test channels quickly, let’s move forward.
