message for a user-defined time (configured by the
TimeForReorderTone parameter) and plays a busy or reorder tone to
the PSTN. Applicable only if the call is released from the IP [Busy Here

'ptime' value in the following precedence: from 'mptime' attribute, from
'ptime' attribute, and then from default value.
