When a person answers the line the other phones continue to ring for a short period of time. The DSS keys are slow to update so the other users cannot tell who picked up the call. Not sure where the lag is coming from as the sip trace shows the ringing to all the phones within milliseconds not seconds as the customer is reporting.

Yealink SIP-T46S 66.81.0.110

Help Please

Hi,

From your description, customer is using ring group feature, which is a server side feature, suggest customer double check with the server side first.
Anything I can help, please feel free to let me know.

The server side shows the correct sip call flow where all phones are told to ring within milliseconds of each other. The issue is the receiving end where the phones are. Is there anyway to estimate the required bandwidth to ring 9 phones including 9 DSS keys showing each users phone ringing ?
