Not quite true. There are 31 channels (to be more precise 32 time-slots 
of which 31 can be used) and if there is no signalling on the span, all 
31 can be voice channels

This is wrong! sigchans should always be defined *after* the voice 
channels


And this is also valid configuration for example:
cicbeginswitch=1
channel=2-62
sigchan=1

Then you have 61 voice channels numbered from 1 to 61
