Put iproute2 and tc on the firewall. Limit the traffic out of the firewall to the T1 router to 1500kbps. There are tons of shaping scripts out there but I prefer something I rolled together and use myself: http://www.mixdown.ca/~andrew/dump/rc.tc. I don't profess to be a traffic shaping guru and if anyone has any suggestions on how to make it better I'd be grateful but it seems to work very well for me. I can completely saturate my ADSL uplink (800kbps) without really bad degradation in my outgoing audio (there is some but it's not bad according to the other side). > I can't change the T1 router to something that supports QOS because it has > certain redundant features with an ISDN line which are needed. You could always use a Sangoma A101u and a CAPI card in a Linux box. :-) The HDLC features in the Digium T100P are still being ironed out, IIRC. Sangoma's been doing it for literally years if not coming up to a decade yet. I've got a friend who's been using an older (DSU/CSU-less) version of their T1 card for at least that long. -A. _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
