How do I block incoming calls? I have someone calling our hotel non stop!

Hi. Thank you for this information. Is there a way to delete a DSS contact?

This guide is incredibly helpful! We often need a quick tutorial for our clients when setting up new Thirdlane Multi Tenant PBX instances with hardware phones like this. Your clear instructions have significantly streamlined our process with this Yealink model. Thanks!

Great video! Thanks for sharing! As an MSP, we've deployed Grandstream phones in conjunction with a variety of PBX platforms for many of our clients. Our current setup, which pairs Grandstream hardware with Thirdlane Multi Tenant PBX - great combo and fantastic phones!

how do you check messages remotely ? How do you forward the calls ?

Is there a way to lock the keypad of GXP2170 while you need to leave it unattended and to unlock it when you need to use it?

I see how they asnwer all these questions. We are supposed to be able to record calls and tehre is NOTHING that tells you how.

Super helpful. Something CIP should have provided themselves. Thanks!

Also, is there a way to deactivate getting missed call log if we don't need to see it?

HELP please. #8 function to forward message is NOT working on our phones. How can we get that activated? Thanks in advance! :)

But how do you press # in response to an in call prompt? I can't tell you how many times I have been asked to "Please press pound to proceed." and have been unable to do anything.

my bluetooth is missing how do I get it back?

I need your help. How can I edit a missed call to be able to add prefix "9" in order to call back the missed call number on a Grandstream GXP2170. Thanks in advance.

Is it possible to add a programmable line key or multi-purpose key to connect the phone to an analog trunk on an FXO port? And I don’t mean using a dial pattern.

when adding a number to 'Blacklist' will that block any future incoming calls from that number on all phones in our office or just the extension that set it to 'Blacklist'...???

After trying to find out why our new Yealink T48s would automatically send calls to voice mail, display an unknown orange arrow at the top of the screen that would not go away, as well as displaying a "forward to: 13" message, when calls came in, I decided to research the matter on RUclips. I came across this video and learned that the transfer button was the problem. Somehow, it had been turned on. This video has saved me from returning the phone to the company, and having to be without office communication for a week. Thank You.
