[Asterisk-Users] Call forwarding

I've done something similar.  I have a relatively small PBX configuration and
all extensions are SIP phones assigned a 6 digit or less extension number. 
I've built a custom macro that determines how many digits need to be dialed and
then based on the number of digits it either prefixes SIP/ or Zap/  to the
actual Dial command.  It works like a charm!
