What systems are compatible with Nextiva Trunking?

Nextiva can host a variety of different SIP-capable PBX systems. Nextiva cannot directly support any analog-based PBX systems, however we do support a variety of Analog Telephone Adapters (ATAs). Below, we have included a list of recommended PBX systems known to work with the Nextiva Service.

With any PBX platform, it is necessary to have a local IT Administrator capable of registering, connecting, and configuring the PBX system to Nextiva’s Trunking service. If you are unable to find an IT Administrator we recommend you inquire about our hosted PBX services as our Technical Support team is thoroughly trained in these services.

Note: Due to the multitude of available PBX systems capable of connecting to Nextiva’s SIP trunking service, our technical support is limited in nature to any features, setup or information relevant to ensure a fully functional PBX. Nextiva has information that will help you register your local PBX to our SIP service. Any questions regarding the functionality of the PBX would be better directed to the manufacturer of the PBX.
