Some time to time, usually after an asterisk restart or a sip reload, some realtime sip peers are loaded in memory without their mailbox. I was not able to replicate the issue on a constant basis, but after adding some additional logs to asterisk, it seems the “add_peer_mailboxes” is run correctly, but then, when the SIP SUBSCRIBE arrives, the mailbox is not found. If I run a SIP SHOW PEER, the peer is shown without the mailbox.

Have you ever noticed a similar behavior?
