Ok, this is might be why.  I have seen before that the numbering for 
the CICs can be different.  If they are in a contiguous block (1-15 
maps to CICs 1-15 and 17-31 map to CICs 16-30) this is how you set it 
up:
cicbeginswith=1
channel=1-15
channel=17-31

If the are not a contiguous block of CICs (1-15-maps to CICs 1-15 and 
16-31 maps to 16-31) you have to do it like this:
cicbeginswith=1
channel=1-15
cicbeginswith=17
channel=17-31

That makes sense I think.  It doesn't matter how it resets it (two 
messages or one) if you're doing a group reset, but that may indicate 
that you have your CICs off in how they are configured.  I think 
chan_ss7 already assumes that you skip that CIC in the channel setup 
IIRC (though I could be wrong).  I just wrote it in this way so that 
CIC mapping to channels may be a bit more configurable.
