VoIP
Telnyx
Carrier with its own IP network and per-connection controls, chosen where route quality and granular trunk configuration matter.
Security & hardening
- Credential or IP authentication
- Encrypted signalling and media
- Outbound spend and destination limits
Telnyx SIP connection architecture
Per-connection configuration on a private carrier network, with outbound voice profiles keeping cost and destination policy explicit.
-
01
Telnyx network
- SIP connections
- Outbound voice profile
- Numbers / DIDs
Profiles cap destinations and spend at the carrier, not only in the PBX.
-
02
Authentication
- IP authentication
- Credential auth
- TLS / SRTP
Encrypted signalling and media where the endpoints support it.
-
03
PBX
- Trunk registration
- Codec policy
- Failover route
Codec list kept short and deliberate to avoid unnecessary transcoding.
-
04
Operations
- Call detail records
- Quality metrics
- Alerts
Route quality reviewed with real call data rather than assumed.
Frequently asked questions
IP or credential authentication?
IP authentication for fixed-address PBXs, credentials where the address changes. Both together where the platform allows it.
Why does audio quality vary by destination?
Route selection and transcoding. Reviewing per-destination metrics and restricting codec negotiation usually resolves it.
Can we run Telnyx alongside an existing carrier?
Yes. Dual carriers with priority routing is the normal design u2014 one is primary, the other takes traffic when it fails or for specific destinations.
