Please consider expanding Physical Interfaces > PHONE x ToneOnPrimaryServiceDown choices to include the full spectrum of choices available in Digit Maps (pg's 201-202 in Device Admin Guide), versus the current limitation of no DT, normal DT, and SITs. This would be ideal for trunk groups, where typically second (di2) or outside (od) dial tone is set on the ** service route access code for selecting other trunk(s) in the tg. In this way, the ToneOnPrimaryServiceDown would be consistent, making it immediately obvious upon lifting the handset that the call will go out via second (or whatever) choice route. It would also be more end-user friendly, since normal DT imparts no info, and the other choices imply that the phone service is totally out of order.
