the called party missed this call, IPPBX system will store this 88686547096 with
extension number 401 into its database. Later on, if the called party tried to call back, the
IPPBX system gets +88686547096 as the caller ID and matches from it database, once
successfully matched, this call will be automatically directed to extension 401.
