Re: [Asterisk-Users] hangup lag causing the answering of already answered calls
Well I've found out what was causing my duplicate logging: it was entirely a NAT issue. Found out it was only happening on some remote endpoints (and not all of them), and that different routers proved to not have duplicate logging. What part of NAT could cause this? Was it really sending all packets twice, or something like that? Just seems kinda strange. Anyway, it's no longer a problem. My original problem, however, remains. Phone doesn't stop ringing when it's meant to. Only happens when call is via my ZapATA. Any ideas/help/input is appreciated! Regards, Carey.
