There are few hardcoded limits:
in libss7
ss7_internal.h	SS7_MAX_LINKS	4
ss7_internal.h	SS7_MAX_ADJSPS	4

in Asterisk 1.8 and up to trunk
sig_ss7.h	SIG_SS7_MAX_CHANNELS	672 (which is 1 DS3 = 28 T1 or about 22 E1)
which is equal to MAX_CHANNELS in older versions
sig_ss7.h	SIG_SS7_NUM_DCHANS	4   (in older versions is just NUM_DCHANS)

also NUM_SPANS = 32 unless you have compiled asterisk with the 'lots of
spans' option in which case it is 128

in short upgrading will not solve your problem - you should change the
hardcoded value and recompile.
In my opinion it is safe to increase them all from 4 to 16 (links, adjspc
and dchans)
