Toshiba ip5631-SDL

Hello HishamElghotmy,

The Zoom Phone certified device list is located here.

We may be able to attach devices with a generic, third-party SIP profile if the device is TLS 1.2 capable.

This device is an older device and after a little research does not look like it supports TLS 1.2 (Transport Layer Security) protocol.

If it does in fact support TLS 1.2, then while it may be attached via a generic sip profile, you would have to lean on Toshiba for troubleshooting.

Thank you.
