Telnyx + Kalem

Lower-cost SIP trunking with global PSTN reach.

Telnyx Voice API and SIP Connections work natively with Kalem. Common choice for higher-volume outbound dialers thanks to per-second billing and competitive international rates.

Setup

  1. Create a SIP Connection in the Telnyx Mission Control portal.
  2. Set the Outbound Voice Profile and assign your DID numbers.
  3. Add Kalem's SIP URI as the destination for inbound calls.
  4. In Kalem, go to Trunks → Add Trunk → Telnyx and paste credentials.
