Modem Result Code | This modem result code will be used to compare against the actual result code returned from the modem after it has finished outdialing the MWI string. If they are not matched, NuPoint Voice will retry the MWI request again later on. Recommendation: For *better display* of CDR events, please turn OFF the Local Echo mode of the modem, ie. if the modem has dialed a MWI string like "ATDT*13658", it should not echo back this same string prior to returning the result code. If event messages for modem dial result are desired, enable "Pager" CDR in the Event Recorder menu. | See Valid String Characters table below.
