add multiple pages of presence to our Yealink phones

We are trying to add multiple pages of presence to our Yealink phones. The only way to do this is for RingCentral to add that line of code to the phone’s firmware and then it’ll work.

Yealink did not provide a firmware version, they said that RingCentral just needs to add that line of code to their existing firmware to get multiple pages of presence working.
