Chapter 6 Cisco Unified Serviceability Alarms and CiscoLog Messages
Error-Level Alarms
This alarm provides the list of unavailable remote peers, where each peer is separated by semicolon. It
also provides the reason code received by the SIP trunk, in response to an Options request sent to remote
peer. For each peer, the alarm provides the hostname or SRV (if configured on SIP trunk), resolved IP
address, port number, and reason code in the following format:
ReasonCodeType=ReasonCode.
The ReasonCodeType depends on a SIP response from the remote peer as defined in SIP RFCs (remote),
or depends on a reason code provided by Unified CM (local).
The examples of possible reason codes include:
• Remote = 503 ("503 Service Unavailable" a standard SIP RFC error code)
• Remote = 408 ("408 Request Timeout" a standard SIP RFC error code)
• Local = 1 (request timeout)
• Local = 2 (local SIP stack is unable to create a socket connection with remote peer)
• Local = 3 (DNS query failed)
For Local=3, IP address in the alarm is represented as zero, and when DNS SRV is configured on
SIP trunk then the port is represented as zero.
