Backup SIP User ID
Specify the SIP User ID for the second backup SIP Server. This parameter
becomes the user portion of the SIP-URI for the device's extension on the second
backup SIP server. Enter up to 64 alphanumeric characters.
Backup SIP Auth ID
Specify the Authenticate ID for the second backup SIP server. This parameter is
required for SIP registration authentication. Enter up to 64 alphanumeric characters.
Backup SIP Auth Password
Specify the Authenticate Password for the second backup SIP server. This
parameter is required for SIP registration authentication. Enter up to 64
alphanumeric characters.
Re-registration Interval (in seconds)
The SIP Re-registration interval (in seconds) is the SIP Registration lease time, also
known as the expiry. The supported range is 30-3600 seconds. Enter up to 4 digits.
Remote SIP Port
The Remote SIP Port is the port number the device will use as the destination port
when sending SIP messages. The default Remote SIP Port is 5060. The supported
range is 0-65536. Enter up to 5 digits.
Local SIP Port
The Local SIP Port is the port number the device will use to receive SIP messages.
The default Local SIP Port is 5060. The supported range is 0-65536. Enter up to 5
digits.
SIP Transport Protocol
Choose the transport protocol for SIP signaling. This will affect all extensions,
including the Nightringer. Default is UDP.
TLS Version
Choose the TLS version for SIP over TLS. Modern security standards strongly
recommend using TLS 1.2.
Verify Server Certificate
When enabled, the device will verify the authenticity of the server during the TLS
handshake by its certificate and common name. The TLS handshake will be aborted
if the server is deemed to be inauthentic and SIP registration will not proceed.
Outbound Proxy
Enter the Outbound Proxy address as an IPv4 address in dotted decimal notation or
a fully qualified domain name (FQDN). When an IP address is configured, the
device will send all SIP messages to this IP address. When an FQDN is configured,
the device will run DNS NAPTR, SRV, and A queries on the FQDN to resolve an IP
address to which it will send all SIP messages. This field can accept entries of up to
255 characters in length.
Outbound Proxy Port
The Outbound Proxy Port is port number used as the destination port when sending
SIP messages to the outbound proxy. A value of 0 will default to 5060. The
supported range is 0-65536. Enter up to 5 digits.
Use Cisco SRST
When enabled, the backup servers are handled according to Cisco SRST
(Survivable Remote Site Telephony). It is required for use in clustered Cisco Unified
Communications Manager topologies.
Disable rport Discovery
Disabling rport Discovery will prevent the device from including the public WAN IP
address and port number in the contact information that is sent to the remote SIP
servers. This will generally only need to be enabled when using an SBC or SIP ALG
in conjunction with a remote SIP server.
Unregister on Boot
When enabled, the device will send one registration with an expiry of 0 on boot.
Keep Alive Period
The minimum time in milliseconds between keep-alive packets sent for nat traversal.
A value of 0 will disable keep alive packets.
SIP Ring Strobe Settings
The following strobe settings will only appear if a CyberData Strobe product is
connected to your device. If a CyberData Strobe product is not connected to
your device, you will not see the strobe settings.
Blink Strobe on Ring
When selected, the Strobe will blink a scene when ringing.
