ExpiredVigorBX 2000 - Configuring a DrayTEL SIP Trunk
The DrayTek VigorBX 2000 can have up to 12 SIP trunks configured for use with with up to 50 Alias / DDI numbers that can be linked to the SIP Trunks. This guide will demonstrate how to configure the PBX system to work with SIP Trunks from the ITSP (Internet Telephony Service Provider) DrayTEL.
DrayTEL provide two connection methods that can be used with the DrayTek VigorBX 2000:
- Recommended Configuration - This would be used when the PBX system has a direct connection the internet i.e. the internet connection is a public IP address and not an RFC 1918 private IP address
- NAT Configuration - This configuration would be used when the PBX system does not have a direct connection to the internet i.e. the internet connection is provided by another router and/or the PBX system has an RFC 1918 private IP address (192.168.x.x, 10.x.x.x and 172.16.x.x to 172.31.x.x) for its WAN interface
Recommended Configuration
To configure the DrayTEL SIP Trunk on the PBX system, go to [IP PBX] > [Trunks] > [SIP Trunk] and select an available Index number:
In that SIP Trunk index, configure these settings:
- Profile Active: Enable
- Profile Name: Give the SIP Trunk a suitable name
- Domain/Realm: Set this to "draytel.org"
- Proxy: Set this to "draytel.org"
- Proxy Port: Set this to 5060
- Display Name: Set this to the desired SIP caller ID
- Account Number/Name: Enter the account number of your DrayTEL account
- Password: Set this to the password for the SIP Trunk
Click OK to save and apply these settings.
The [IP PBX] > [Trunks] > [SIP Trunk] list will then show the SIP Trunk with the status of the SIP Trunk displayed on the right:
- R - the SIP Trunk is registered and can be used to make and receive calls
- - Indicates that the SIP Trunk is configured to register and is currently not registered. It cannot be used to make or receive calls in this state
Once the DrayTEL SIP Trunk is registered with the PBX system, the PBX will handle calls as specified by the Answer Mode of each SIP Trunk; this can be used to route calls to the Auto Attendant, Hunt Groups or individual Extensions. Usage of the Answer Modes is explained in this guide: Routing Incoming Calls on the VigorBX 2000
With the DrayTEL SIP Trunk configured, Extensions registered with the PBX system can make calls using the SIP Trunks either by dialling the trunk number then dialling the desired number or by being routed using the Dial Plan facility. This requires that the extension has permission to use the trunk to make outgoing calls. Configuration of the PBX system to make outgoing calls is explained in further detail in this guide: Making Outgoing Calls with the VigorBX 2000
