Use Case – Configuration Example
...
In this section, we use a typical use case to show you how to configure upper registration feature on Sangoma SBC.
Enterprise PBX/Carrier Soft Switch: IP address | 192.168.100.108 |
SBC Internal IP address | 192.168.100.66 |
SBC External IP address | 10.10.2.10 |
We need to add:
Two Call Routing Profiles | “Inbound_Dialplan” and “Outbound_Dialplan” |
Two SIP Profiles | “Internal_Sip_Profile” and “External_Sip_Profile” |
Two Domains | Upper registration domain “10.10.2.10” |
Call Routing Profile: “Inbound_Dialplan”
| Code Block |
|---|
<extension name="Local_Extension_Inbound">
<condition field="destination_number" expression="^(10[01][0-9]).*$">
<action application="export" data="dialed_extension=$1"/>
<action application="bridge" data="sip/Internal_Sip_Profile/${dialed_extension}@192.168.100.108"/>
</condition>
</extension> |
Call Route Profile: “Outbound_Dialplan”
| Code Block |
|---|
<extension name="Local_Extension_Outbound">
<condition field="destination_number" expression="^(10[01][0-9])@192.168.100.66.*$">
<action application="export" data="dialed_extension=$1"/>
<action application="bridge" data="${sofia_contact(External_Sip_Profile/${dialed_extension}@10.10.2.10)}"/>
</condition>
</extension> |
SIP Profile “Internal_Sip_Profile”
Navigate to “Configuration -> Signalling -> SIP Profiles”:
...
!Security Warning: With Authenticate Calls set to Disable, make sure that your PBX/Soft Switch is set to authenticate incoming calls.
...
SIP Profile “External_Sip_Profile”
For sip profile “External_Sip_Profile”, it is similar to “Internal_Sip_Profile”.
...
“SIP IP Address”: choose the NIC you want to use for SIP listening: in this case it is “10.10.2.10”;
Set “Authenticate Calls” to “Disabled”
Set “Always Use Full Identification” to “Enabled”
Set “Routing Plan” to “Inbound_Dialplan”
Upper Registration Domain “10.10.2.10”
Navigate to “Configuration -> Signalling -> Domains”,
...
*For any registration to domain “10.10.2.10”, Sangoma SBC will use sip profile “Internal_Sip_Profile” to forward it to IP “192.168.100.108”, port “5060” with transport UDP.
...
Bind Domain “10.10.2.10” to external sip profile
Go to “Configuration -> Signalling -> SIP Profiles”,
