Update:
@JParo:
Thanks for your suggestion, but I’m not able to make changes at the certificate, as our PBX is hosted by a provider.
@NickD_3CX and 3cx generally:
I now have bought a brand new
Yealink T48S (touchscreen) and am disappointed (by 3cx and also by Yealink -> see below...).
Done a factory reset first
I don’t have done any FW update and configured the T48 over our SBC with the web interface.
Rebooted…
Device was showed in the 3cx console
Set the T48 to a (my) extension and configured as needed
Rebooted device
Settings were not overtaken - message “update skipped” was showed at the device
Imported the certificate of our 3cx/SIP-Trunk provider (Geotrust Global CA) on the T48S over the web interface.
Disabled „Only Accept Trusted Certificates”
Rebooted device
-> Provisioning have worked, T48S works principally
Removed the imported certificate from device
Enabled „Only Accept Trusted Certificates”
Rebooted device
Provisioning don’t work again
So 3cx (and / or Yealink) has/have a
definitely a problem regarding the certificate (at least Geotrust Global CA).
The
Geotrust Global CA is listed on the Yealink page with the
preinstalled certificates
http://support.yealink.com/faq/faqInfo?id=691
So... same problems here as with the Yeaklink T46s (reason, that I have created this thread)
I definitely can’t live with the “workaround” to import the (should be trusted!) certificate of our provider, wait until it expires and then extract the cert in browser and reimport it again on all devices with the web client!
I’m also not able (and don’t wanted, if I would be able) to apply a “Let's Encrypt SSL Cert” to the 3cx as it is hosted by a provider.
It can’t be that we have to handle such base problems with new mainstream products (Yealink and Geotrust Global CA)
So... please give me a solution, 3cx!
Firmware:
As the T48S was showed in red as “not supported” I wanted to update the FW over the 3cx.
The 3cx console showed 66.83.0.20 as the actual and 66.82.0.20 as the installed FW version
Firmware update over 3cx
don’t work (nothing happens on the T48S device)
Searched for the FW, showed as update in the 3cx console (66.83.0.20) on the Yealink website
=>
Not found (66.83.0
.10 / 66.83.0
.30 / 66.83.0
.35 / 66.83.0
.50 and 66.
84.0.10, but
no 66.83.0
.20! what is strange for me...
Downloaded the FW version
66.83.0.20 from 3cx FW download page and updated T48s manually over web-client
The Device is showed black now
but the FW is way outdated, what is not nice...
Retested problems with certificate mentioned above (only to be sure…) -> same behavior
Disappointed with Yealink T48S (not 3xc related, only as additional information):
Blurry screen, showed text not sharp if the display is viewed in the “standard angle” of about 45 - 60 (with the foot stand) (
T46 display is way better)
Touch screen slow (not responsive)
Setting Label Length to “extended” under Dsskey (in the web client) does not work!
=> Text (e.g. to BLF) is showed in two lines (instead of one) although there is more as enough space on the screen (
this works on the T46S).
=> Posted a thread in the Yealink forum the that issue
