Yeastar Firmware 30.0+ (S Series And Similar Devices)

This guide will help you set up a Yeastar PBX running firmware 30.0+. The unit used in this guide is a S20. The guide will help you add your trunk, an inbound route, and an outbound route to your Yeastar device. 

1. Access your Yeastar PBX GUI by typing it's IP Address in your browser

2. Select the "Settings" icon. Then select "Trunks"

3. Create a new trunk using the image below as a guide. Note that your Trunk Number is found under the "SIP Trunking" tab in your portal and is not the same as your login. The trunk password is found under a link that says "Show Password" in the same tab. 

4. We recommend using the ulaw codec for best voice quality


5. We selected "Qualify" which sends SIP options pings to the gateway to ensure connectivity. This can also be helpful in keeping NAT translations stable. Be sure to add a second entry duplicating all of the settings but replacing "" with "" This will provide a redundant connection to 


6. To enable inbound calling select "Call Control" and then "Inbound Routes"

7. We left the DID pattern blank so as to allow any DID from to call into the Yeastar device. Note that you must select your trunk as a member of the inbound route. We created a trunk for and so calls could reach us from either gateway. If you wish to only allow certain DID's to access your Yeastar device use the DID Pattern 1NXXNXXXXXX (a specific example would be 15557778888).



8. Now add an outbound route.


9. We chose to use "X." for testing which allows us to dial any number of digits. However, North American calls must send 11 digits to us. See our guide on "Outbound Calling" for more information on specific dialing patterns you can use.
