I believe it changed when call completion was added, see below.

/*
  * data is ---v
  * Dial(DAHDI/pseudo[/extension[/options]])
  * Dial(DAHDI/<channel#>[c|r<cadance#>|d][/extension[/options]])
  * Dial(DAHDI/<subdir>!<channel#>[c|r<cadance#>|d[/extension[/options]])
  * Dial(DAHDI/i<span>[/extension[/options]])
  * 
Dial(DAHDI/[i<span>-](g|G|r|R)<group#(0-63)>[c|r<cadance#>|d[/extension[/options]])
  *
  * i - ISDN span channel restriction.
  *     Used by CC to ensure that the CC recall goes out the same span.
  *     Also to make ISDN channel names dialable when the sequence number
  *     is stripped off.  (Used by DTMF attended transfer feature.)
  *
  * g - channel group allocation search forward
  * G - channel group allocation search backward
  * r - channel group allocation round robin search forward
  * R - channel group allocation round robin search backward
  *
  * c - Wait for DTMF digit to confirm answer
  * r<cadance#> - Set distintive ring cadance number
  * d - Force bearer capability for ISDN/SS7 call to digital.
