The only thing in common is that is does happen with calls via SIP trunk, not ISDN and not internal calls. Nothing strange in verbose and SIP logs. Could even be some weird intermittent firewall issue I guess.

Voipmonitor.org is great for debugging voip. You can either use only the
sniffer (opensource) and use mysql + the pcap files or you can also buy
