Presence on Yealink phones.

Have you tried entering via - Press Menu->Call Features->DSS Keys.

I would not have high hopes for this.  RC makes pretty clear they only support features beyond basic in and outbound calling on the Polycom and Cisco phones they support.  That said, I looked at my Polycom web GUI and the format for a BLF looks like: blf5471572012@sip.ringcentral.com  I have no idea how that 10 digit number is derived or if it would work on a Yealink though.

Did this work for you you?  I am having the same issue and haven't been able to get it working yet.

SOLVED

As Brandon mentioned above, click on a user in the User list after logging into your RingCentral account. In the URL there will be a number after "users", that is the number for a BLF string formatted like so:

blf1538357020@sip.ringcentral.com



Then set up your keys in the phone like this:

Did yours all start working immediately?  I tried the same thing on my phones last week when I found this thread and they seemed to get "stuck" at whatever status the BLF line was in when added.  After several power cycles, etc, they seem to be working fine on my phone but not accurately on another T48G we have that has an identical configuration (but another line).

Even Ring Central support couldn't provide a solution so I guess I should just be happy to have a partially working solution at this point.

Yeah they immediately started working. Is your config exactly the same as mine? I'm using two T46S phones. I'm also trying to figure out how to pick up another line that is ringing, if possible.

I'm also trying to set this up. we are using the Yealink T48S, and T23G to test with, so far, it's just holding the solid light on the T23G, and the T48S doesn't show any type of difference...

I just want to say this is a godsend! Thank you so much to Brandon and Jeremy for their input. I just got two Obi1062 phones and entered the blf123456789 (my url only had 9 digits) as the value for the number section for the key.

Spent 4 hours on this. Thought I would have to give up. Thank you both again!

Hello, we tried setting this up on a Yealink T46S on a Firmware Version: 66.81.25.9. It did pop up with the Line keys for each extension but the LED won't change it's color when someone else is on a call. Do you think it would be something with the firmware version?

I may have cracked the "code" for the 10 digit BLF string.  In your admin portal navigate to a user and inspect the URL.  Try using that number as the BLF address like blf1234567890@sip.ringcentral.com  Let us know if that works.  I am curious.
