We recently announced a change to the Yealink T19PN as these have been updated to the T19PN E2. The same has now happened for the T21PN these are now T21PN E2.
We’ve tested the new Yealink T21E2 and provisions OK and is able to make calls. The chipset in the phone has changed but functionality-wise, it’s the same as the T21P.
There are a couple of changes you need to be aware of though:
- It has it’s own firmware version and you cannot downgrade it to older versions (this will be a problem for ITSPs who have approved an older firmware on their platform).
- It says “T21 E2” on the front of it.
- It reports itself as a different model number when provisioning (which could cause problems for people who have implemented their own provisioning systems).
