    - Do a typical DNS lookup of FQDN.
  • DNS SRV
    - Send an SRV record to DNS server then upon reply lookup FQDN's via DNS.
A maximum of 99 entries can be added to this table entry. When added via REST any Row ID greater than 99 will be rejected.
ServerTypeYesNoEnum0Possible values:
  • 0 - eConventionalSrvr
  • 1 - eSrvRecordTemplateSrvr

Specifies the method to use to lookup SIP servers
  • eConventionalSrvr
    - A configured server entry defined by IP or FQDN.
  • eSrvRecordTemplateSrvr
    - This is not an actual server but a template which will populate the server(s) once the SRV Query gets a response from DNS.
  • eSrvRecordSrvr
    - The actual server created after SRV Query.
WeightYesNoint0Possible values:

  • 65535 - Maximum
Specifies the weight of the server in case it's defined in the SRV record.
HostYesNostringnone256 - Max Length Specifies the IP address or FQDN where this Signaling Group sends SIP messages. If an FQDN is configured all the associated servers are included and used according to the server selection configuration element.
HostIpVersionYesNoEnum0Possible values:
  • 0 - eVersionPreferIPv4
  • 1 - eVersionPreferIPv6
Specifies whether the FQDN should be resolved into IPv4 addresses or IPv6 addresses. If this is a SRV record, this field specifies whether the resulting FQDNs are resolved into IPv4 or IPv6 addresses. By default, the SBC Edge resolves the FQDN into IPv4 addresses.

  • 1440 - Maximum
Specifies the number of minutes that a socket remains connected to the server.

This option is available when ReuseTransport is Enabled. A value of 0 means ReuseTimeout is set Forever*. Otherwise, the valid range is 5-1440

ProtocolYesNoEnum1Possible values:

    - Send message using TCP.
  • TLS
    - Send message using TLS.
MonitorNoNoEnum0Possible values:
  • 0 - eMonitorNone
  • 1 - eMonitorOptions
  • 2 - eMonitorPing
Specifies the method to monitor server
  • None
    - no monitoring of this server occurs
  • SIP options
    - an Options message is sent to the server
KeepAliveFrequencyNoNoint30Possible values:
  • 0 - Minimum
  • 300 - Maximum
Specify frequency in seconds to determine server availability.

This configuration is available when Monitor is set to SIP Options . If Monitor is not set to SIP Options, this value needs to be 0. Otherwise, this value needs to be in the range 30-300*

RecoverFrequencyNoNoint5Possible values:
  • 0 - Minimum
  • 300 - Maximum
Specify frequency in seconds to check server to determine whether it has become available.

This configuration is available when Monitor is set to SIP Options . If Monitor is not set to SIP Options, this value needs to be 0. Otherwise, this value needs to be in the range 5-300*

LocalUserNameNoNostringAnonymous64 - Max Length The local username of the SBC Edge system.

This configuration is available when Monitor is set to SIP Options

PeerUserNameNoNostringAnonymous64 - Max Length The username of SIP server.

This configuration is available when Monitor is set to SIP Options

PriorityYesNoint0Possible values:
  • 0 - Minimum
  • 16 - Maximum
Specifies the priority of this server. The priority is used to order the server when more than 1 is configured.
RemoteAuthorizationTableIDNoNoint0Possible values:
  • 0 - Minimum
  • 65534 - Maximum
Specifies a Remote Authorization table for this SIP Server, from a list of authorization tables defined in the Remote Authorization Tables. The Remote Authorization table is used by a Signaling group when a challenge (401/407) is issued by the server. The table contains a realm, user name, and password. There are used to provide credentials to he server issuing the challenge.
ContactRegistrantTableIDNoNoint0Possible values:
  • 0 - Minimum
  • 65534 - Maximum
Specifies a Contact Registration Table for this SIP Server,from a list of registration tables defined in the Contact Registrant Tables. The Contact Registration is used by a Signaling Group to register one or more contacts to a registrar.

StaggerRegistrationNoNoEnum0Possible values:
  • 0 - btFalse

ContactURIRandomizerNoNoEnum0Possible values:

  • 1 - btTrue
If enabled, the following will occur: -Random user values will be generated and put into the Contact-URI of each outgoing Register message. -The random user portion will be saved and compared to incoming Invite Request-Uri's. If the prefix of the R-URI contains SBCxxxx, then if there is a match, SBCxxxx will be stripped and the remaining number used to route (if no match, Invite is not accepted). If there is no SBCxxxx in R-URI, then the number is sent as-is for routing.
RetryNonStaleNonceNoNoEnum1Possible values:
  • 0 - btFalse
  • 1 - btTrue
This value will only be visible if Remote Authorization Table are defined in SIP Server. When true, if stale=false is received in 401/407, the SBC Edge will set failed retry timer and re-attempt to send Register with same credentials at expiration. When false, if stale=false is received in 401/407, the SBC Edge will never resend a challenged request with the same credentials.(this is RFC behavior)
TLSProfileIDNoNoint0Possible values:
  • 0 - Minimum
  • 65534 - Maximum
If TLS is selected this specifies the TLS profile this server will use for secure SIP messages.

  • 1 - btTrue
This value will only be visible if both Contact Registrant Table and Remote Authorization Table are defined in SIP Server. When true, the SBC Edge will include authorization headers obtained from previous 401/407 exchange in registration refresh messages. When false, the SBC Edge will not include authorization headers obtained from previous 401/407 exchange in registration refresh messages.
