IT was on this list: -chan_ss7 from Dicea does support 'clustering' -libss7 (native SS7 implementation from Digium) currently does not. (so it does not support mtd3). BTW: solutions like sangoma mtp3d_boost _could_ support clustering, but unfortunately i couldn't find any reliable partner of Sangoma in my country to see Sangoma's SS7 solution in practice. you could do cost-effective implementations with fail-over (not loadsharing) with hardware from RedFone or simple switch (simple electrical relay at RJ45 level ) with so-called 'chan_failover', Even openss7 implementation at this area is 'poor' so currently you need to stick with Dicea or write your own corrections to libss7 Regards,
