I use the Zoiper softphone app on my android phone.
	
	
		
	
		Is there a way to change the default port in it somewhere.  When I open 5060 on my router to let Zoiper connect with my pbx server, it causes major security issues.  
	
		I end up getting bombarded with hack attempts to the point that the server is inoperable.
	
	
		
	
		thanks for info
