Your patterns don't match.  You are sending 127-1 at vvfarm-extensions, but 
vvfarm-extensions has no pattern xxx-1.  Same problem in the other 
direction.  Try changing the dial statement in server A from:

exten => _11XXX,1,Dial(iax2/vvfarm/${EXTEN:2}-1,20)

to:

exten => _11XXX,1,Dial(iax2/vvfarm/${EXTEN:2},20)

and in server B from:

exten => _17XXX,1,Dial(iax2/colo/${EXTEN}-1,20)

to:

exten => _17XXX,1,Dial(iax2/colo/${EXTEN},20)
