Description: This table reports historical data for SIP method request and response code statistics for each method and response code combination in a given past interval. The possible values of interval will be previous 5 minutes, previous 15 minutes, previous 1 hour and previous day. To understand the meaning of interval please refer section in description of ciscoSbcStatsMIB. An exact lookup will return a row only if - 1) detailed response code statistics are turned on in SBC 2) response code messages sent or received is non zero for given SIP adjacency, method and interval. Also an inexact lookup will only return rows for messages with non-zero counts, to protect the user from large numbers of rows for response codes which have not been received or sent.
