With traditional IP-PBX, your IP-PBX will be using an internal IP address assigned by your in-house router, in order to connect it from outside, usually, you’ve to configure DDNS, port forward, firewall etc.
In comparison, Yeastar Cloud PBX uses the public IP addresses to enable you to connect from anywhere without a special configuration on your router.

However, in a corporate environment, there is still a chance that you will face problems connecting to the Yeastar Cloud PBX server, or even if you can connect, you will have a problem to do calls. If this happens, we would need customers to perform some tests to confirm and replicate the problem first.

Step 1: Verify if it’s our server problem.

User to install Linkus mobile (not the desktop version) for their extension, connect via 4G and make some calls and see if there is any problem?

User instruction here.

Step 2: Verify if it’s the client home router is good.

User to install Linkus mobile (not the desktop version) for their extension, connect via home WiFi and make some calls and see if there is any problem.

Step 3: Test your microphone and speaker for Linkus desktop before making calls.
This can be an issue as it appears some of the user’s actual problem is with the microphones. Please make sure the mic and speaker are both working first before doing calls. After confirmed the mic and speakers, are you able to do calls now using your office laptop now?


Step 4: Test Linkus for desktop with a non-office computer/laptop with 4G connection. (Repeat step 3 when necessary) This is to double confirm again if it’s related to your office laptop only.

Step 5: Test linkus for desktop with a non-office computer/laptop with Home WiFi connection. (Repeat step 3 when necessary)
Confirm again if your home WiFi is good for VoIP/linkus desktop.

The above tests will take about 30 min to finish, with these test done, we can have some idea if the problem comes from the equipment provided from your company only, and we will tackle it from there.
