About account status changes

[lucho...@gmail.com]

I want to manually switch the status of the logged in account, such as online, offline, busy, leaving, etc.I will not receive incoming calls and calls from other sip accounts,May I ask how I should use SIPek to implement it, or which part of the SDK has an implementation method for me to use?My English level is limited. If my expression is not clear enough, please reply to me and continue the discussion. I really hope to get your help.thank you very much!
