VoIP
SignalWire
API-first voice platform from the FreeSWITCH lineage, used for programmable trunking and low-latency media alongside conventional SIP endpoints.
Security & hardening
- Per-endpoint credentials
- TLS/SRTP
- Rate and destination controls
SignalWire trunking and programmable voice
FreeSWITCH-derived platform combining conventional SIP endpoints with programmable handling for calls that need application logic.
-
01
SignalWire cloud
- SIP endpoints
- Numbers
- Relay / scripts
Application logic runs at the provider where it must survive PBX maintenance.
-
02
Authentication
- Per-endpoint credentials
- IP restriction
- TLS/SRTP
Separate credentials per endpoint so one leak is contained.
-
03
PBX / app
- Trunk to PBX
- Programmable flows
- Recording
Clear split between calls handled by the PBX and calls handled in code.
-
04
Controls
- Rate limits
- Destination policy
- Usage alerts
Ceilings set before campaigns or integrations go live.
Frequently asked questions
When does programmable voice beat a PBX flow?
When routing depends on external data u2014 order status, account tier, agent skill from another system u2014 or when the flow must be version-controlled and tested like code.
Can it terminate to our existing Asterisk?
Yes. The trunk registers or authenticates by IP exactly like any other carrier connection.
Is it suitable for high concurrency?
Yes, with capacity agreed in advance and rate limits configured u2014 the same sizing discipline applies as with any carrier.
