Hello all, This is a repeat email; I have no idea how/where to solve this problem, google seems to indicate it's a frame slip problem, but there appear to be no resources with relevant information -- this is my second request for any pointers, information, anything! The symptom is a loud, brief buzz, almost exactly every 6 seconds, on the dot. It is only audible to remote parties, when I use an analog phone connected to my Digium TDM card. All other audio through my Asterisk box is fine, including SIP phones, music on hold, voicemail, etc. But when the TDM400P is bridged to the PSTN through my IAX2 provider, I get this repeating buzz! I've upgraded Asterisk to 1.0.7 on my gentoo linux system; I have a genuine Digium TDM 400P with 1 FXS and 1 FXO, I'm only using it as an ATA currently. Much thanks in advance for any information, pointers, hints, or recommendations that anyone can provide! -Trent Tuggle
