What systems are compatible with Nextiva PBX?

Nextiva can host to a variety of different PBX systems. Specifically, Nextiva caters to typically any “SIP PBX” option. Nextiva cannot directly support any analog-based PBX systems. Below, we have included a list of recommended PBX systems.

With any PBX platform, it is necessary to have a local administrator capable of registering and connecting the PBX system to Nextiva’s trunking service.

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.

PBX Systems capable of connecting to Nextiva’s SIP trunking service:

  • SwitchVox
  • TrixBox
  • Elastix
  • 3CX

If you have questions regarding Nextiva’s SIP trunking solutions, please contact our Amazing Service team at 800-285-7995 from 5:00am – 6:00pm AZ time Monday-Friday, or Saturday from 9:00am – 1:00pm AZ time. Or, simply email us at

What routers are compatible with Nextiva service?

Check your physical network hardware and have this information available when setting up your router in your Nextiva account.

With Nextiva service, most routers can be set up to work with VoIP phones.  Our Amazing Support Team will always put our best effort into making your current network setup work as-is before suggesting changes.

However, not all routers have been tested to work with VoIP, and some are just not compatible.

In order to ensure the best call quality, we do suggest getting one of the following routers:

  • Linksys WRT54GL
  • Netgear WRN 3500L V2

Both of these routers allow a third party firmware, called Tomato, which can allocate bandwidth to ensure your phones have enough Internet speed.

If you have any questions directly ask an Amazing Service Team member here or email us at
