Anyone seen this one before? Asterisk Box (A): ATA186 SIP -> Asterisk Asterisk Box (B) Asterisk -> ZAP E1 Boxes linked by IAX2. ATA user places call to PSTN via box a & b. Call fails and user hangsup. Box A CDRs reports call duration = 2 minutes Box B CDRs reports call duration = 3 hours How can this happen? I assume that if a IAX2 HANGUP is missed the protocol fully retries until done? Is it possible that HANGUP events do not retry as much as normal events? Linus
