E2 have more memory and probably better cpu. For example t19 wont accept sha256 signed certificates, because of memory constrains or at least that what I've been told from yealink. On 03/11/15 01:58, Pete Mundy wrote:

Hi list,

Does anyone here have any information they can share on what the difference is with the new 'E2' variants of some of Yealink's phones?

We have a reasonable number of YL phones in our fleet, and a few months back we noticed our new stock was starting to be supplied as SIP-T21P E2s after SIP-T21P went EOL with our country's distributor (which was not long at all after SIP-T20P went EOL!).

We now have SIP-T19P E2s arriving new too (instead of SIP-T19 prior).

These new E2 variants use different hardware identifiers and run different version numbers. They look to use a different build of a the same source code. They don't appear to accept downloaded configurations from the non-E2 variants.

Just wondering if anyone in the know can share what the change is under the good?

Only for interest's sake really. I've done a bit of Googling, but haven't determined much other than that TI Titan and Aries seem to be used in other products. I'm guessing it's perhaps a change of CPU platform or some other chipset change.

Pete
