some observations

Hey Markus,

Well a very tricky question to answer, but to me if the stuff is  
hampering the business / direct cash, then it's high time to go with  
some commercial solution, nevertheless if time permits you can also  
check with chan_ss7 too.

Let me know in either case,

Thanks & Regards,
