IPComms SIP Trunking vs Telnyx SIP Trunking

IPComms SIP Trunking connects a business PBX or session border controller to the public telephone network over the internet. The standard trunk has no per-channel fee or fixed channel count; concurrent calls depend on bandwidth and a fraud-protection limit that support can raise on request. SIP signaling is supported over UDP or TCP on port 5060 and TLS on port 5061, with G.711 μ-law, G.711 A-law, and G.729 codecs. IPComms lists two geographically separate US points of presence, inbound delivery to both, and automatic outbound failover. Trunks can use TLS signaling and SRTP media, and calls receive STIR/SHAKEN A attestation. The company lists compatibility with multiple PBX systems, Microsoft Teams Direct Routing, and contact-center connections. Its REST API supports number provisioning, trunk management, sub-account creation, and call-detail retrieval. Usage is billed from a prepaid balance. The service has a free plan, with paid service from $1.50/mo; E911 with a dispatchable location is available for $2.50 per number per month. A 30-day test trunk is available on request with limited call capacity and destinations.

Telnyx SIP Trunking connects business phone systems to phone networks over the internet, rather than a traditional phone line. Telnyx says its service runs on a private global network it owns. The product is available in 230+ countries and Telnyx reports processing 500M+ SIP calls monthly. Features include HD voice using wideband codecs such as AMR-WB, branded calling, STIR/SHAKEN A-level attestation, CNAM, spam protection and Voice Integrity reputation monitoring.

Listed PBX compatibility includes 3CX, FreePBX and Asterisk; integrations include Microsoft Teams, Zoom Phone, Talkdesk, UJET and Genesys. The free plan has a $0 platform fee, with usage billed per minute. US local outbound rates start at $0.005 per minute and inbound at $0.0032 per minute; rates vary by destination and volume. Committed starts at $500 a month, and Enterprise at $5,000 a month.
