Fusion offers one of the most extensive lists of interoperable IP-PBXs and IADs in the industry. We keep this list up-to-date by maintaining engineering and support relationships with our IP PBX and sales partners.

The list below represents some of the many PBX manufacturers whose equipment has been deployed using our SIP Trunks.
