FANVIL i16sV - Opening code "1234" with a Yealink Phoe

[Arthur.b]

Hello,
We are using a Fanvil i16sV with the access code "1234" to open a door from a Yealink T54W desk phone. In version 18, we configured a BLF key with a custom call shortcut to directly send the code "1234" and allow one-click door opening. However, since upgrading to version 20, pressing this BLF key no longer sends the code but instead initiates a new call.
Do you have a solution to configure a shortcut on a Yealink T54W to send the code "1234" to the Fanvil i16sV?

Hello,

I found a way :
Create a DSSKey form the web interface of the Yealink in DTMF type, i tried to re-provisioning the phone after that and it don't loose the key.
however on the 3CX interface, you can't see this new Key.

Hope it can help !
