SIPProfile[1..1]DefaultTransport
Select the transport protocol to be used over the LAN.
Requiresuserrole: ADMIN
Valuespace: <UDP/TCP/Tls/Auto>
UDP: The system will always use UDP as the default transport method.
TCP: The system will always use TCP as the default transport method.
Tls: The system will always use TLS as the default transport method. For TLS connections a
SIP CA-list can be uploaded to the video system. If no such CA-list is available on the system
then anonymous Diffie Hellman will be used.
Auto: The system will try to connect using transport protocols in the following order: TLS,
TCP, UDP.
Example: SIP Profile 1 DefaultTransport: Auto
SIPProfile[1..1]TlsVerify
For TLS connections a SIP CA-list can be uploaded to the video system.
Requiresuserrole: ADMIN
Valuespace: <On/Off>
On: Set to On to verify TLS connections. Only TLS connections to servers, whose x.509
certificate is validated against the CA-list, will be allowed.
Off: Set to Off to allow TLS connections without verifying them. The TLS connections are
allowed to be set up without verifying the x.509 certificate received from the server against
the local CA-list. This should typically be selected if no SIP CA-list has been uploaded.
Example: SIP Profile 1 TlsVerify: Off
