Built for practical SIP deployments

  • PBX and UC interop

    Use VoiceTel with Asterisk, FreePBX, FreeSWITCH, FusionPBX, SBCs, hosted PBX platforms, and contact centers.

  • Registration or IP-auth

    Connect to VoiceTel's network by Anycast or Geocast. We support Digest and IP authentication methods.

  • Redundancy planning

    Route design covers primary and failover trunks, POP preference, number routing, and cutover rollback.

  • Emergency calling

    Emergency-service configuration is tied to numbers, service addresses, and clear limitations disclosures.

  • BYO SBC

    VoiceTel can sit behind customer-owned SBCs where architecture and security requirements call for it.
