+ DAHDI allows several modifiers to be specified as part of the resource.
+ The general syntax is :
+ Dial(DAHDI/pseudo[/extension])
+ Dial(DAHDI/<channel#>[c|r<cadance#>|d][/extension])
+ Dial(DAHDI/(g|G|r|R)<group#(0-63)>[c|r<cadance#>|d][/extension])
+ The following modifiers may be used before the channel number:
+
+
+ Search forward, dialing on first available channel in group (lowest to highest).
+
+
+ Search backward, dialing on first available channel in group (highest to lowest).
+
+
+ Round robin search forward, picking up from where last left off (lowest to highest).
+
+
+ Round robin search backward, picking up from where last left off (highest to lowest).
+
+
+ The following modifiers may be used after the channel number:
+
+
+ Wait for DTMF digit # before providing answer supervision.
+ This can be useful on outbound calls via FXO ports, as otherwise
+ they would indicate answer immediately.
+
+
+ Force bearer capability for ISDN/SS7 call to digital.
+
+
+ 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.)
+
+
+ Specifies the distinctive ring cadence number to use immediately after
+ specifying this option. There are 4 default built-in cadences, and up to 24
+ total cadences may be configured.
