Frequently Asked Questions
Common questions about wholesale SIP trunking services.
Wholesale SIP trunking provides high-volume voice connectivity at discounted per-minute rates for resellers, MSPs, ITSPs, and businesses with large call volumes. Instead of retail per-channel pricing, wholesale customers receive custom rate decks based on their monthly minute commitment, with volume discounts that increase as usage grows.
SIP origination (inbound) handles calls coming from the PSTN to your SIP infrastructure — callers dial a phone number and the call is delivered to your system over SIP. SIP termination (outbound) routes calls from your SIP infrastructure to the PSTN — your system sends a SIP INVITE and we connect the call to a landline or mobile number.
Yes. IPComms offers white-label SIP trunking that allows resellers, MSPs, and ITSPs to offer SIP trunking services under their own brand. You set your own pricing, manage your own billing, and maintain direct customer relationships while we provide the underlying carrier-grade network infrastructure.
Wholesale pricing is available starting at 10,000 minutes per month. Volume tiers at 100,000+ and 1,000,000+ minutes per month unlock progressively lower rates. Contact our wholesale team for a custom rate deck based on your specific traffic profile and volume.
Yes. IPComms supports number porting for both local and toll-free numbers across the United States and Canada. Porting typically takes 7–14 business days for local numbers and 5–10 business days for toll-free numbers. You can start using IPComms immediately with new numbers while your existing numbers are being ported.
Yes. IPComms provides API access for programmatic number provisioning, CDR retrieval, and account management. The API allows you to search and activate DIDs, manage trunks, pull real-time call detail records, and integrate with your existing billing and provisioning systems.
