Telnyx SIP Trunking
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. To place or receive calls, customers create a SIP connection, link it to an outbound voice profile, assign a Telnyx number and use a softphone. 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.
