For the record: Google still prominently points to this page for configuration backup: http://wiki.snomone.com/index.php?title=Configuration_Backup which makes you wonder why the option is missing until you find this topic here. And I agree with Stefano. An explicit *configuration* backup would be very nice. The backup is so huge only because it includes loads of call records and things which I would not even want in a reconfigure from scratch scenario.

For the record: as the PBX was up for ~9 months, I simple restarted it. This cleared the issue. The log was not really helpful in this case, see: [8] 20140722141631: HTTP/NTP/SNMP client waited for 60 s [5] 20140722141657: Identify trunk (IP address/port and domain match) 4 [5] 20140722141837: Last message repeated 4 times [3] 20140722141837: DoS protection: Not accepting more calls [5] 20140722141857: Identify trunk (IP address/port and domain match) 4 [8] 20140722141927: Trunk 4: Preparing for re-registration [8] 20140722141927: Trunk xxx: Sending registration to xxx.xx [8] 20140722141927: Answer challenge with username xxx [8] 20140722141927: Trunk 4: setup callback to send re-registration after 240 seconds [5] 20140722141927: Identify trunk (IP address/port and domain match) 4

I run into the same error with a PBX which (so far) was basically idle: just 3 phones plus one firewalled SIP trunk. So there really, really are not too many calls and no malicious IP is involved. What are the expected default values for this max_udp_invite?
