Our current IP phone infrastructure uses Zultys ZIP 36G phones, and we are evaluating a switch to Zoom. Do you know whether these Zultys phones are compatible with Zoom or have any details about their compatibility?
Thanks

hi
Zoom Phone Certified Hardware 2026-05-18 support article does not list Zultys ZIP 36G phones as being supported. I think that Zultys ZIP 36G model was first released in March 2015 which makes this a pretty old model.
The support article does list Zoom certified desk phones from manufacturers such as AudioCodes, Avaya, Cisco, Grandstream, Mitel, Poly, and Yealink. Zoom Certified desk phones have extensive features and support Zero Touch Provisioning (ZTP). ZTP makes these phones very easy to setup.

I would not recommend it, but you can use Generic SIP desk phones such as Zultys ZIP 36G phones if they support TLS 1.2 or higher. For security, use secure real time protocol (SRTP) with AES 256 encryption. Generally, Zoom Phone supports generic SIP desk phones for basic features such as making and receiving calls and may not support SRTP.
Alternatives to desk phones include free Zoom PC clients and mobile apps. These clients have much greater functionality than desk phones and generally support all Zoom Phone features.
