SIP Bridge Variables

Table 1. SIP Bridge Variables
Variable	Description
IP Address of the Virtual Unit	Virtual IP address, for information only. Address cannot be changed as it is defined when the virtual unit is created.
Use Windows Authentication for Database Connections	Specify whether Windows authentication should be used for database connections. The selection is on by default, and we recommend using it. With Windows authentication, you can leave database password fields empty. If you de select the option, SQL logon is used, and you must enter database user name and password for each database connection, and they are saved in registry and log files as plain text.
Log File Directory of the Virtual Unit	Software running in the virtual unit uses this directory for their log files.
SIP Bridge Port for Call Dispatcher(s)	Specifies the TCP/IP port used by Call Dispatcher when connecting to SIP Bridge. The default value is 21007.
Certificate store (SIP)	Certificate store location for certificate, the default value is HKLM/My.
Certificate Common Name (SIP)	Common Name part of the Certificate Subject, Issued To
Certificate Issuer (SIP)	Optional certificate issuer name, Issued By.
Internal Server Certificate in Use	Internal Server Certificate can be used to secure server-server connection.
Internal Server Certificate Common Name	Internal Server Common Name part of the Certificate Subject, Issued To.
Internal Server Certificate Issuer	Optional Internal Server Certificate issuer name, Issued By
Internal Server Certificate Store	Internal Server Certificate store location
Configuration Database Server Address or Name	By default, the value defined in database installation is used automatically.
Configuration Database Name	By default, the value defined in database installation is used automatically.
Configuration Database User Name	By default, the value defined in database installation is used automatically.
Configuration Database Password	By default, the value defined in database installation is used automatically.
Advanced Parameters
Registration Timeout (Seconds)	Registration timeout for SIP phones (seconds). Default is 120.
SIP Session Expiration (Seconds)	SIP session expiration (seconds). Default is 1800, not in use 0.
Minimum SIP Session Expiration (Seconds)	Minimum SIP session expiration in seconds, used in SIP header as Min-SE. The default is 180, the minimum value is 90. Added in SP03.
SIP Session Refresher	SIP session refresher is negotiated. If the caller uses refresher parameter in the SIP message INVITE, the callee must respect the value; otherwise the callee can decide the refresher (uac or uas as described in rfc 4028). 0 = Caller refreshes, uac used in INVITE and OK (unless the caller decides otherwise); 1 = SIP Bridge refreshes, uac used in INVITE, uas used in OK, if possible; 2 = Other end refreshes, uas used in INVITE, uac used in OK, if possible; 3 = Callee refreshes, uas used in INVITE and OK, if possible. Default is 1 (Sip Bridge). Added in SP03.
UDP Port for Inbound SIP Messages	UDP port for inbound SIP messages. Default is 5060.
TCP Port for Inbound SIP Messages	TCP port for inbound SIP messages. Default is 5060.
TLS Port for Inbound SIP Messages	TLS port for inbound SIP messages. Default is 5061.
Use R Number	Call signaling uses the redirecting number instead displaying the original A number with redirected calls.
Display Names in SIP Messages	Display caller names or numbers provided in SIP messages.
Use Diversion Header as Caller Info	Display the original caller’s number when a call is diverted to Sinch Contact Center system and Diversion header is available in the incoming SIP message. Added in SP06.
Use CD-Controlled Transfers	Use Call Dispatcher-controlled transferring operations instead of the bridge controlled ones. If you use REFER mechanism in SIP, remove selection.
Authentication Level	Authentication of endpoints. 0 = No Authentication: user authentication is not required, 1 = User-Specific: authentication is done only if the SIP authentication password is specified for a user, 2 = Forced for All Users: all users must have an authentication password. The default value is 0, No Authentication.
Maximum Number of Simultaneous Calls	Maximum number of simultaneous calls (sip dialogs/call legs). Default is 0 (no limit). Added in SP03.
Traced B-Numbers	Inbound calls to these B-numbers are traced to logs in highest detail. Separate multiple B numbers with a comma. Moved in SP07 to Logging Wizard, see Operation Guide section Logging.
Allow SIP Registration for Listed Hosts	Comma-separated list of accepted host(s) for which the SIP registration is meant. As of 1705 the following comment is obsolete: In ECF environments enter here the SIP Host Name(s), see Agent Server variables. Added in 1608.
