What's the SBC Password for?

[saint__]

Hi,

When you install a SBC, under SIP Trunk / General / Connection Information, what's the Password field for?
During the SBC Installation, I only used the generated key.
At the SBC OS Level, I have my own root password.
So what's that password field for?

Thank you all.

The password is for the authentication handshake between the PBX and the SBC.

The password is for the authentication handshake between the PBX and the SBC.

My apologies.
By searching a little deeper, I found out that the Authentication Key is not really a key but rather a URL and that the password is actually the password for the link between the SBC and 3CX.
Thanks!
