Dear Kamailio Server’s Developers

I’m an user who trying to discovery supported features of Kamailio server (for a client application that connect to server).

Thank you all for made a beautiful thing like Kamailio.

Could you guys please help to clear my some questions as below:

- If I make a mobile application (something like Zoiper application), does Kamailio server support if I want to develop group chat feature in my application. If so please share the message request flow that I have to send to server and format of message request. - Could you guys please share some document that describes detail about format for each SIP request message (INVITE, REGISTRATION, OPTION, MESSAGE…)

Thank you in advance for your supported.
