Our verdict on Telnyx SIP Trunking
Telnyx SIP Trunking provides PSTN connectivity for businesses using compatible softphones, PBX systems, and communications applications. It supports inbound and outbound calling, phone-number provisioning, SIP connection management, international coverage, and API-based connection setup. The service runs across web and API interfaces, with JavaScript listed for SDK support. Its feature set is aimed at teams that need business calling infrastructure rather than a broad, multi-purpose Voice API platform.
Pricing is usage-based rather than seat-based. The advertised starting rate is $0.0032 per minute, with rates varying by destination and volume tier. Pay as you go has a $0 per month minimum, standard usage rates, no contract requirement, and automatic tier discounts as usage increases. Committed requires a $500 per month minimum and adds discounted usage rates, a named account manager, priority support, and higher limits. Enterprise requires a $5,000 per month minimum and adds dedicated infrastructure and IPs, private interconnect, in-region GPUs, and unlimited rate limits.
Caller identity and call protection are central strengths. Telnyx includes branded calling, STIR/SHAKEN caller authentication, CNAM caller-name presentation, outbound spam protection, Voice Integrity, and call recording through its voice services. HD Voice and wideband codecs support higher-quality calling, while softphone integration provides an ecosystem fit for compatible calling setups. Choose it when SIP trunking, PSTN connectivity, and caller identity controls are the priority. Teams looking for a broader Voice API scope or wider platform coverage may prefer a more expansive alternative.
