What kind of problems you had? Have you used timers in your config?

I am running several servers (with 2 or more trunks each) here for well 
over 3 years (starting with Asterisk 11 and now 13) without any problems 
and with peek loads that fill all 8 E1 on each server
Can't this be considered as "serious ss7 solution that will work 
properly"
