Howdy all 1. does anyone know a good voip / sip / qos monitoring tool? 2. Has anyone had luck running asterisk phone systems over DSL? 3, Has anyone used sonic wall routers for qos over dsl. The company I am consulting for would like to install asterisk boxes over dsl with sonicwall routers. For the last 4 years I have installed all my boxes over t1 lines with cisco routers and have had no sound problems, The couple of clients we tried this out on are having sound issues so you see why I would like to find a good monitoring tool. We are using Broadsoft SIP trunks. Thanks for any suggestions. Michael D Mosier -------------- next part -------------- An HTML attachment was scrubbed...

I think DSL is 1/2 duplex and in most cases way to slow on the way Up for VOIP. I use a sonic wall on a T1 and it works great. It even has some features for tweaking VOIP. Any time I have tried VOIP on a 1/2 duplex connection all the way up to 7down and 1.5 up I have call quality issues.

If you make this by your own, you will only have a one way solution which only helps for outgoing call legs, not incoming. DSL isnt Half duplex as Michael Wilson said, but the frequency used for upstream is lower range. Or is it an sdsl connection and not adsl? If its sdsl or gshdsl or something like this, the frequencys used are the same range for up and download. the best way to do this is to ask for an QoS for your DSL from your ISP.> > We are using Broadsoft SIP trunks. > > Thanks for any suggestions. > > Michael D Mosierbest regards steve smith
