Overview
This document will guide you through the process of configuring the Session Border Controllers to work with Switchvox. There are two major applications - 1) SIP Trunking solutions, 2) Remote Phone solutions. This document describes the configuration of SIP Trunking.
Introduction
For Trunking solutions, SBC to Switchvox Configuration Guide provides detailed information about the configuration requirements in the SMB SBC, Vega SBC, Netborder SBC and the Software VM SBC. A typical deployment connects SIP Trunking Service Provider across Internet or other networks into the SBC, where the SBC provides Security, Routing, Interoperability and more, then delivers the SIP Trunk call to the Switchvox IP-PBX. Using SIP Protocol the SBC and the Switchvox create a Trunk together.
SIP Trunking
Bringing SIP Trunks from SIP Trunking Service Providers into the SBC and then deliver the SIP Trunk calls to the Switchvox.
Switchvox IP: 192.168.77.112
SBC LAN IP: 192.168.77.124
SBC DMZ IP: 10.10.32.170
SBC Public WAN IP: 104.145.12.182
ITSP FQDN: itsp.sangoma.com
...
Note: In the following configuration example, this is a DMZ-LAN setup of the SBC, and the Switchvox is located on a Private LAN. This is one of many different network topologies that the SBC supports. Not all network topologies will be documented in the document, please consult other Wikis for slight changes in deployment styles of the SBC. Slight changes in configuration from this example to other network topologies are expected.
Switchvox Configuration
General Configuration
The Switchvox will typically have a Static IP or Fully Qualified Domain Name. In this configuration we are defining the SBC as a VoIP Provider, then assigning a Outgoing Calls and Incoming Calls to/from the SBC.
VoIP Provider
Open the VoIP Providers tab. ( Setup > VoIP providers )
...
Click "Save SIP Provider"
...
Incoming Calls
Open the Incoming Calls tab. ( Setup > Incoming Calls )
...
Click "Save Single DID Route"
...
Outgoing Calls
Open the Outgoing Calls tab. ( Setup > Outgoing Calls )
...
Click "Save Outgoing Call Route"
...
SBC Configuration
General Configuration
The following configuration will focus on the Switchvox to SBC requirements. It is only half of the configuration needed for proper operation, as the SIP Trunking Service Provider will also need to be configured, along with the External WAN interface and external SIP Profiles and related configuration. The document will reference the SIP Trunking Service Provider but not show how to configure the provider. There are other Wiki's that document how to configure SIP Trunking with SIP Trunking Service Providers.

IP Settings | Network
The default IP Address of the SBC is 192.168.168.2 root/sangoma The IP Address needs to be changed and a new admin user created.
...
At this point you can access the SBC from the New LAN IP Address.
IP Settings | Media Interfaces
Go to Configuration | IP Settings | Media Interfaces
...
Ensure the Transcoding Mode is to Hardware Hidden mode for all Vega SBC and Netborder SBC. Then click Save.
| Info |
|---|
Note: For SMB SBC and Software VM SBC the Transcoding Mode is to Software. The click Save. |
...
Next click Detect Modules. Once you modules are detected click OK to continue.
...
Next go to Configuration→Media→Media Profiles and edit the default media profile. Set Code#1 and Code#2 as shown below, ensuring both are 20ms. The remaining codecs set to nothing which is the first option in the drop down.
...
IP Settings | Access Control Lists
Go to Configuration | IP Settings | Access Control Lists
...
Policy: Set to Allow
IP Address: Here you will need a list of any IP Address(es) used by the SIP Trunk Service Provider - Enter the Network Address or IP Address and Mask
...
Signaling | SIP Profile
Two SIP Profiles are needed. One for the LAN side - for 'Internal' communications with the Switchvox, and another for the WAN side - for 'External' communication with the SIP Trunk Service Provider.
...
Display Name: Give the SIP Profile a name. ServiceProvider_External
User Agent: This is the name displayed on the User-Agent Header. Does not need changing.
SIP IP Address: Select the LAN IP Address of the SBC
External SIP IP Address: Enter in the WAN IP Address of the Firewall/Router. This setting is only used when the SBC is behind a Firewall/Router.
Port: Port 5060 is default.
Transport: Select the Transport you want to use, UDP+TCP is default. Or individually UDP or TCP.
RTP IP address: If different than the SIP IP Address, select the IP here.
External RTP IP address: Enter in the WAN IP Address of the Firewall/Router. This setting is only used when the SBC is behind a Firewall/Router.
SIP Trace: Optional: Enable. It is useful when you have a problem.
Strict Security: Optional. Enable when strict security is required, here all traffic from non whitelisted and/or registered IP addresses, on that SIP Profile, will be blocked. This means that with this feature enabled you need to assign ACLs or register endpoints in order to be able to make calls through the profile. Enabling in SIP Trunking solutions, allows the SBC to lock down to specific SIP Peers.
Authenticate Calls: Select Disable,
ACL for Inbound Calls: From the Available list, select and use the Arrow key to move over the Internet_WAN_External_ACL list created earlier.
...
Press Save
...
Signaling | SIP Trunks
Two SIP Trunks Profiles are needed. One for the Switchvox and another for the SIP Trunk Service Provider. SIP Trunks Profile is where the Peer attributes are configured.
...
Display Name: Give any Name. ITSP
Domain: Enter the IP Address or FQDN of the SIP Trunking Service Provider. itsp.sangoma.com
User Name: Specific to Service Provider requirements.
Authentication User Name: Specific to Service Provider requirements..
Password: Specific to Service Provider requirements..
From User: Specific to Service Provider requirements.
From Domain: Specific to Service Provider requirements.
Transparent CallerID: Select Enabled.
Transport: Select UDP
OPTIONS Ping Frequency: Optional: Enter 60 for 60 Seconds
OPTIONS Max Ping: Optional: Enter 5 for 5 tries
OPTIONS Min Ping: Optional: Enter 5 for 5 tries
SIP Profile: Select the "ServiceProvider_External" SIP Profile created earlier
...
Press Save
...
Routing | Call Routing
The SBC will require two Call Route Dial Plans. One Dial Plan to send calls from the Switchvox to the SIP Trunking Service Provider, and another Dial Plan to send calls from the SIP Trunking Service Provider to the Switchvox.
...
Your Call Routing should now look like this for Inbound Calls to the Switchvox.
...
Signaling | SIP Profile
Two SIP Profiles were created earlier. We need to go back and assign the appropriate Call Routing Dial Plan to the correct SIP Profile. The Inbound_Calling Dial Plan is assigned to the ServiceProivder_External SIP Profile, as calls from the SIP Trunking Service Provider will will be going Inbound_Calls to bridge to the Switchvox. And the other direction, the Switchvox will call the Switchvox_Internal SIP Profile which will go to the Outbound_Calling Dial Plan, which will bridge the call to the SIP Trunking Service Provider.
...
Under Session Routing change the Routing Plan to Inbound_Calling. Then click Save to continue.
...
Apply Configuration
You are Done. Time to save your efforts.
