[Linphone-developers] I need your help

[Wang Ming]

Dear Developers.

I wanna to use Flexisip and linphone android client.

I have installed flexisip server on my VPS, so i can use linphone mobile 
client with my VPS server now.

I have some questions on that.

Linphone chat message and Sip calls are using only my own server? Or 
using other server such as linphone.org?

And Where are the chat message history and calls history stored in?

If you know it, let me know.

Best regards.
