*Yeastar strives to ensure interoperability with SIP trunk partners around the globe with in-depth testing. These SIP trunk providers have passed the compatibility test with Yeastar Cloud PBX and pre-configured templates are included in Yeastar Cloud PBX that make configuration easy and quick. Select country to view a list of supported SIP trunk providers in your country, however, do take note that this list is NOT exhaustive.

Option 2: Bridge with a Yeastar Gateway

Currently using Landlines or ISDN and don't want to switch to a SIP Trunk? Yeastar Gateways provide the solution for retention of your existing lines on the Yeastar Cloud PBX.

Landlines are traditional telephone lines with physical cables, also known as POTS/PSTN/CO or hunting lines.  Retain your landlines with a Yeastar TA gateway.

Digital lines are widely used by businesses. Bridge the connection between ISDN 10/ ISDN 30  (RJ-48c/ T1/E1/PRI interfaces) and Yeastar Cloud PBX with a Yeastar TE gateway.
