Incrediblepbx on centos 7

Hello,

i have installed incredible pbx succesfully on my server.Also able to make call from my pc as i whitelisted my ip.
But the problem is cant use it on my phone? because i think of the dynamic ip of my ips or the wifi area i am.
How to setup my pbx for my android phone so i can use anywhere where i get internet acces.

Thx
