I know this subject has been discussed before, but this time it’s a different question.
I use the device on a smart home. There is only the 3710 available, as intercom I use directly the devices of the house like Tablet and Smart Home App.
As ringing event I monitor the SIP call INVITE sip:192.168.0.1.
Up to firmware 184.108.40.206 it works without problems.
Bell button --> Ding Dong
Starting with firmware 220.127.116.11.
Bell button --> Ding Dong --> BEEEP BEEEP BEEEP
That beep is annoying, I want to turn it off. What has changed in the firmware? Is the Grandstream expecting a response to the Invite command? If so, what would the response packet look like?
