Interop Partners

We have close relationships with the leading SIP platform providers in the world and actively ensure operability testing with these partners. Our close relationship and interoperability with these major platform vendors allow our products to be seamlessly deployed by service providers throughout the world.

Platform Partners

All Grandstream IP surveillance products are based on the open-source SIP platform – just like all of our IP voice and video telephony products. In addition, Grandstream surveillance products are certified by ONVIF – an independent organisation that sets technology standards for the IP surveillance market. Grandstream IP surveillance products are interoperable with any SIP-based platform and any ONVIF certified product or service.

 Video Surveillance Partners

Our IP voice and video telephony devices run the open-source SIP platform and are therefore interoperable with a variety of third party SIP products and services – including SIP PBXs, SIP software, IP door phones and more.

 Technology Partners

Our online portal is a one-stop shop for Grandstream resellers, offering marketing collateral, product images, support resources, firmware as well as recent and upcoming news and event.
