FAQ

Wholesale VoIP, answered.

Proactively answering FAQs boosts user confidence and cuts down on support tickets.

Wholesale VoIP termination is the service of routing large volumes of outbound voice calls over IP networks at bulk carrier rates. Businesses and resellers use it to reduce per-minute costs significantly versus retail SIP trunking.
Same day. After account approval (typically under 2 hours), you receive SIP credentials and can begin testing immediately. Full production traffic is usually live within 24 hours.
No. Ringflow wholesale VoIP operates on a pay-as-you-go model with no monthly minimums, no setup fees, and no long-term contracts. Volume discounts apply automatically as your usage grows.
Supported codecs: G.711 (μ-law and a-law), G.729, G.722 (HD), and OPUS. Protocols: SIP over UDP/TCP/TLS, SRTP for media encryption, and T.38 for fax over IP.
CLI routes pass your caller ID to the terminating network, resulting in higher answer rates. Non-CLI routes strip or modify caller ID and are priced lower. CLI Premium routes deliver ASR of 55–65%.
