Description | This trap indicates that at least one SIP registrant has a source port number that changed over two or more consecutive REGISTER refreshes, possibly indicating that the registrant was unreachable from the SBC for a time. The NAT between the SIP endpoint (IAD) and the SBC is closing its pinhole before the IAD sends a REGISTER refresh to the SBC. |
Repetition | None |
Objects | None |
Action | Check Registration refresh timing between IAD and SBC together with the NAT pinhole timing. |
