Unfortunately I've attempted all of the above without success. It seems to me from a digital set there is a longer delay than from analog before I can send DTMF to the valcom for zone selection. If I pick up the handset on the 39xx and dial slowly (very lol) I can cut through to the zone and page. Also have both ADL and Hot D configured, no luck. Also attempted HOT L, no success. Note on the HOT D a # was not accepted and if I attempted *(s) for pause(s) while configuring the HOT D, 4 *s would exit me from the load ... interesting ...
