The Enable Tunnels to Master Devices checkbox enables the 
Quadro as a slave device and allows connecting to the master 
Quadro via SIP tunnel. When this checkbox is enabled the 
Tunnels to Master Devices table needs to be configured. 
The link Tunnels to Master Devices moves you to the page 
where a list of master devices needs to be defined. 
Fig. II-218: SIP Tunnel Settings – Tunnels to Master Devices page 
The Tunnels to Master Devices page consists of a table where master devices are listed with the corresponding authentication parameters. 
Add functional button leads to the Add Entry page where a new master device parameters needs to be provided. 
The Add Entry page consists of the following components: 
The Enable Registration checkbox selection is used to enable 
the registration to the corresponding master device. 
The  Tunnel Name 
text field requires the SIP tunnel name for 
the corresponding connection. System suggests you to start the 
SIP tunnel name with the “SIP_Tunnel_” words, according to the 
automatic prefix used for the SIP tunnels on the Quadro, 
however this is not mandatory. 
The  User Name  text field requires the authentication user 
name. The field in front of this text field displays the default non-
editable prefix for SIP tunnels: “SIPTunnel_”. 
The Password text field requires the authentication password. 
Please Note: The User Name  and Password  should match 
both on master and slave Quadros for the successful SIP tunnel 
establishment.

The Master device IP text field requires the IP address of the master device. 
The Master device port text field requires the SIP port number of the master device. 
The Registration State field displays information whether the slave device is registered on the master or not. 
The Registration Date/Time field displays the time and the date of last registration on the master’s device. 
Call Routing  
The Call Routing service simplifies the calling procedure for Quadro users, i.e., different types of calls (internal, SIP, PSTN or IP-PSTN) can be 
placed in the same way. SIP registration is not needed for extensions to make routing calls.  
The Call Routing page offers the following components: 
• When the Route all incoming SIP calls to Call Routing 
checkbox is disabled, for all incoming SIP calls Quadro will 
first search the incoming SIP address in the 
Extensions 
Management 
table. If found, the incoming SIP call will ring 
on the corresponding extension. If not found, Quadro will 
look for a matching routing rule in 
Call Routing table. 
When the Route all incoming SIP calls to Call Routing 
checkbox is enabled, for all incoming SIP calls Quadro will  
directly look for a matching routing rule in 
Call Routing 
table and will ignore the possible matches in the 
Extensions Management table.  
Fig. II-220: Call Routing page 
Attention:  Regardless of whether the Route all incoming SIP calls to Call Routing  checkbox is selected or not, SIP calls from external 
callers will or may go to the Call Routing table, so any unprotected routing rule can be misused. That is why it is strongly recommended to 
secure the rules in the Call Routing table by setting the filtering or authentication options. 
The Call Routing Table link leads to the Call Routing table where routing patterns may be manually defined. 
The 
Local AAA Table link leads to the page where local AAA (Authentication, Authorization, and Accounting) database can be managed.
