Configure a SIP Trunk

To start with, you need to have an account from Nexphone. Please visit their website to get a SIP account: www.nexphone.ch
2. Add a SIP Trunk in S-Series VoIP PBX
After you get the SIP trunk account, you need to add a SIP trunk in Yeastar S-Series VoIP PBX.
Go to Settings > PBX > Trunks, click Add.
3. Configure the Nexphone trunk
In the new window, select Switzerland from the “Select Country” drop-down list and select Nexphone from the “ITSP”.
- Name: give this SIP trunk a name to help you identify it.
- Protocol: SIP.
- Trunk Type: Register Trunk.
- Transport: UDP.
- Username: your Nexphone Account username.

- From User: the same as the user name.
- Password: your Nexphone Account password.
- Caller ID Number: your Nexphone Account DID number.
4. Check the Trunk Status
Click Save and Apply. Go to PBX Monitor to check if the SIP trunk is connected successfully as the screenshot below shows.
Configure the Outbound Route with Nexphone Trunk
To make outbound calls via the newly created SIP trunk, you need to configure an outbound route for the trunk.
1. Create an Outbound Route
Go to Settings > PBX > Call Control > Outbound Routes, click Add.
2. Configure the Outbound Route
The system compares the number with the pattern that you have defined in your route 1. If it matches, it will initiate the call using the selected trunks. If it does not, it will compare the number with the pattern you have defined in route 2 and so on. The outbound route which is in a higher position will be matched firstly.
You can adjust the outbound route sequence by clicking these buttons
- Route Name: give this outbound route a name to help you identify it.
- Dial Patterns: set the dial patterns. As the settings below, to make calls via the SIP trunk, you need to precede the number to be dialed with the prefix 8.
- Dial Pattern: 8.
- Strip: 1
- Member Extensions: select the extensions that are allowed to make calls through the outbound route.
- Member Trunks: select the Nexphone trunk.
3. Click Save and Apply
Now you can make outbound calls through the Nexphone trunk. As the dial patterns configured above, you need to dial “8” before the destination number.
For example, to call the number “4101234567”, you need to dial “84101234567” on your phone.
Configure the Inbound Route with Nexphone Trunk
To specify how calls from the Nexphone trunk should be routed, you need to configure an inbound route for the SIP trunk.
1. Create an Inbound Route

2. Configure the Inbound Route
- Name: give this inbound route a name to help you identify it.
- Member Trunks: choose the Nexphone trunk.
- Destination: select the destination where the incoming calls will be routed.
3. Click Save and Apply
When you call in the SIP trunk, the call will be routed to the destination configured on the inbound route.
