sipCommonNotifSequenceNumber

This object contains a sequence number for each notification
generated by this SIP entity.  Each notification SHOULD have a
unique sequence number.  A network manager can use this
information to determine whether notifications from a
          
particular SIP entity have been missed.  The value of this
object MUST start at 1 and increase by 1 with each generated
notification.  If a system restarts, the sequence number MAY
start again from 1.
