Configures the fallback mechanism for the SIP provider line.
- SNMP ID:
- 2.33.4.1.1.38
- Console path:
- Setup > Voice-Call-Manager > Lines > SIP-Provider > Line
- Possible values:
- No
- No fallback to an unencrypted connection is performed. If it is not possible to establish an encrypted connection to the VoIP provider, the line remains unregistered.
- UDP
- As a rule, encrypted SIP connections are made with the TCP protocol and unencrypted connections are made with the UDP protocol. This setting switches directly to an unencrypted UDP connection if the encrypted TCP connection cannot be established.
- Complete
- If an encrypted TCP connection with the configured TLS version cannot be established, then attempts are made to establish an unencrypted TCP connection, and finally a UDP connection in order to register the VoIP line.Note: This setting provides the best compatibility, but may lead to a longer registration time.
- Default:
- No
