Bug report: Hotdesk is not working, when RSTP forced on T54W

[PBX128]

Hello,

Unfortunately, we had to realize that 3CX Hotdesk does not work if the RSTP setting is set to “obligatoire” on the Yealink T54W phones. user-Logins are not accepted.

Only when we set RSTP on the phone to "deactivated" or "optional" it works.

Please correct this security problem. Thank you very much!

Versions:
v20 Update 4
Yealink T54w with newest firmware

Hello, how is the phone connected to the PBX?
Also, what exactly "logins not accepted" means?

 

[PBX128]

The phone is directly connected (LAN) to 3CX server (DMZ).
This problem only exists with phones configured for Hot Desk.

After entering *77*{xxx}* for login, there is an error message "Not acceptable".

This behavior is by design: HD users in the PBX have SRTP switched off and any attempt to manually enforce it will fail.
So this is basically a feature request that should be posted in the Integrations/Other > Ideas
