In this article, you can find an up-to-date phone support guide (last update: 07-07-2026) with defintions of what levels of support we offer and which phones have been put in which category.
Support levels
There are four levels of support for phones in Compass:
- Certified: the phone has been tested by Talksome to work with Compass and will be tested before every release with the latest firmware available at that time, which will become the recommended version after it passes the tests. In addition, these phones are autoprovisioned by Compass and receive full support by our service desk.
- Supported: the phone has been tested by Talksome to work with Compass at some point in time. In addition, these phones are autoprovisioned by Compass and receive best effort support by our service desk.
- Known working: the phone has been reported to work by a partner. They are however not tested by Talksome and also don’t receive support. They have to be provisioned manually or via flexible provisioning.
- Deprecated: the phone model had the status Certified or Supported but is End-of-life. They no longer receive testing effort, support or autoprovisioning and are removed from Studio and API. They can be re-added by partners via flexible provisioning.
