Hi SamyGo,

Thank you for the response, When I enabled/disabled Call feature like DND, All call forward etc in IP Phone (Yealink T42S).

IP Phone sends Subscriber request to Kamailio but Kamailio responded with Bad Event.

Also, Presence is not working with IP Phone but it working with Zoiper.

Please find attached Kamailio loaded modules section and it's configuration and SIP message.

If you need any more information please let me know.

Thank you for your time.

Hi All,

I am facing issue while SIP REGISTER. Allow methods and Allow Event SIP Headers are the mission of 401 Unauthorized and 200 OK on Successful SIP Registered.

Please find the attached document in which I mention both working and nonworking SIP Message.

It would be appreciable if anyone help figures out this issue on Kamailio server.

Thank you.
