OCSG and SS7
                     hi,
	
	
		
	                
                I need help in using OCSG Parlay Audio Call Services (Third party call, call notification, play audio etc). From the documentation i have learned 
	
	that there are three ways to do that namely: SS7, SIP, OSA PArlay gateway. 
	
	I require some info for SS7 connectivity of OCSG with underlying GSM network. OCSG dictates for INAP/SS7 connectivty we should use Tieto's SS7 stack-in
	
	-box. But the documentation also reveals that OCSG INAP plugin communicates with Tieto's SS7 stack using JAIN (Java Api for INAP). Since OCSG
	
	is using JAIN, which is a standard therfore i beleieve is should be able to use any proprietary SS7 stack not just Tieto's. If any one has done
