Settings
Providers and PBXs
To prevent anyone from eavesdropping VoIP conversations, you can
encrypt these connections. The connection setup and termination, and also
signalling, are encrypted with SIPS. The call data is encrypted with SRTP.
Important:
If you are using this on the PBX, the PBX specifies the
encryption method. The PBX overwrites manual settings.
Desactivado
: Forces de-activation of call data encryption by SRTP. The
connection is not established if the call partner (VoIP provider, other PBX in
the sub-system operation, external VoIP subscriber) requires call data to be
encrypted by SRTP.
Preferido
: Switches on negotiation for the encryption of call data by SRTP.
When a call is made, the call partner will be asked if encryption is possible.
If so, the call data will be encrypted and then transmitted, if not, the call data
will not be encrypted.
Obligatorio
: Forces activation of call data encryption by SRTP. The
connection is not established if the call partner (VoIP provider, other PBX in
the sub-system operation, external VoIP subscriber) does not support the
encryption of call data by SRTP.
NUMBER SETTINGS
Utilización de números de línea externa
Public exchange subscriber numbers must be used for PBXs which allow
you to dial external telephone numbers without preceding exchange line
access numbers or characters (e. g. 0 or **). Such PBXs automatically
detect whether exchange line access is required or not.
