Note:
•
If the device receives a SIP 408 response, an ICMP message, or no response,
alternative routing is still performed even if the code is not configured in the
Alternative Routing Reasons table.
•
SIP requests belonging to an SRD or IP Group that have reached the call limit
(maximum concurrent calls and/or call rate) as configured in the Call Admission
table are sent to an alternative route if configured in the IP-to-IP Routing table for
the SRD or IP Group. If no alternative routing rule is located, the device
automatically rejects the SIP request with a SIP 480 (Temporarily Unavailable)
response.
