Vonage (now part of Ericsson) bundles SIP trunking into a UCaaS platform with per-user pricing and contract commitments. IPComms is pure SIP trunking that works with your existing PBX — pay only for minutes used, no per-seat fees, and no contracts.
Vonage is a UCaaS platform that bundles phone service, video, and messaging into per-user plans. If you already have a PBX, you're paying for features you don't need.
Vonage charges $19.99-$34.99/user/month for VBC or $24.99/line/month for SIP trunking — whether you use 10 minutes or 10,000. IPComms charges per minute of actual usage, so you only pay for what you use.
Vonage typically requires 1-3 year contracts for their best pricing, with early termination fees if you leave. IPComms is month-to-month — cancel anytime, no penalties, no commitments.
Vonage user reviews frequently cite inconsistent support experiences, especially for SIP trunking versus their core UCaaS product. IPComms specializes in SIP trunking and PBX connectivity — it's all we do.

Here's what a typical business with 10 lines actually pays per month with each provider.
Example: 10 DIDs, 5,000 outbound min, 3,000 inbound min
Same setup: 10 SIP trunking lines (unlimited domestic calling)
Pricing based on publicly available rates as of March 2026. Vonage SIP trunking includes unlimited domestic calling, but businesses with low to moderate call volume overpay significantly compared to usage-based pricing. Vonage may require contracts for best rates.

Absolutely. IPComms is pure SIP trunking designed to work with any SIP-compatible PBX: Asterisk, FreePBX, 3CX, FreeSwitch, FusionPBX, Issabel, Kamailio, Yeastar, Cisco CUBE, Avaya, Genesys, and Microsoft Teams via Direct Routing. Vonage primarily pushes their own UCaaS platform (Vonage Business Communications), and their SIP trunking product is secondary to their core offerings.
IPComms charges per minute of actual usage, not per user or per line. You pay $1.50/month per DID number, $0.009/min for inbound calls, and $0.010/min for outbound calls, with $0 channel fees. Vonage charges per user ($19.99-$34.99/user/month for VBC) or per line ($24.99/line/month for SIP trunking). If you have an existing PBX and moderate call volume, IPComms' usage-based model is significantly cheaper.
IPComms provides real human support via phone, email, and ticket for all customers — no minimum spend required. Our team specializes in SIP trunking and PBX connectivity. Vonage's support quality varies by plan tier — basic plans may only get chat and email support, and user reviews frequently cite inconsistent support experiences, especially for SIP trunking issues versus their core UCaaS product.
