SIP operators tested and certified with MaxiPBX
The SIP trunk is the connection that links your PBX to the telephone network. Rather than promising universal compatibility, we certify operators one by one: each trunk listed here has been tested and validated in real conditions by our teams.
What « certified » means to us
A certified operator has passed our complete validation protocol on a production MaxiPBX instance:
- Incoming and outgoing calls validated, including under load
- Correct number presentation (CLIP) in both directions
- DTMF, transfers and call forwarding verified end-to-end
- Controlled behavior in case of outage and failover
- Documented and reproducible configuration for rapid deployment
Select a country first
The certification of a trunk depends on the country, the operator and its technical profile. Choose a country to display only the operators validated or being certified on this market.
