DTMF Detection:
If callers are complaining of being misdirected when they select options at the
Auto Attendant, then these values might need to be adjusted.
Minimum time: The default setting of 45ms should be adequate for most
environments. It may however be necessary to lower this value if TalkSwitch
appears to have trouble ‘hearing’ digits when dialed at the auto attendant. It
might need to be increased in cases where the system is ‘hearing’ ghost DTMFs
and accidentally misdirecting callers.
Maximum time: The default setting of 65ms should be adequate for most
environments. In most cases this value only needs to be bumped up a bit to help
the system deal with echoed digits seen from cell phones. For example: calls keep
being misdirected to extension 111. This usually indicates that even though the
caller may have dialed 113, TalkSwitch sees 1113 because the ‘1’ was echoed by
the cell phone network. Once TalkSwitch captures 3 digits, it will ignore the rest,
hence the digits ‘111’ will be accepted and the ‘3’ ignored.
