[SR-Users] Does Kamailio provide any API for other program to create sip account

[Xiangwen Chen]

Hello,

I am developing a sip VoIP app in IOS, which want to provide the feature of allowing user to create sip account from client side.  I use Kamailio as sip server.
My thought is when user register to the the user account system, the user account system can communicate with Kamailio, create a sip account associated with the user and pass the sip account to the client, the client then can configure itself using the sip account. 
Does Kamailio provide any API  or module for me to do this?
Thanks!
