From page 121 of the OBi Device Administration Guide (Version 23.03.11: 23 March 2011):
=====
Invoke Second Dial Tone in Digit Map
You can tell OBi to start a tone after a certain pattern of digits have been dialed by specifying the element {t=<tone>} within a digit map, where <tone> is a 1 to 3-letter name of the tone to play. The tone will stop when the next digit is entered.
For example:
(**1{t=di2}(Msp)|**8{t=od}(Mli))
which tells the device to play Second Dial Tone when **1 is dialed, or play Outside Dial Tone when **8 is dialed.
=====
Is this actually implemented in v1.2.0 (Build: 2102)? I put this example (using Msp1) in the PHONE Port DigitMap and no new dialtone was started after **1 or **8 was dialed. This is a feature I really like and use frequently in the PAP2.
Am I missing something?
