One thing I will say is that my test environment isn’t exactly huge, I'm using Asterisk with 2 x100p's (PSTN access) and voiptalk here in the UK. They offer an IAX2 trunk -> PSTN gateway service. I also have a voiptalk SIP account that I test with as well.
I have tried a few other adsl routers before I tried this, namely a Solwise SAR715 ADSL Router and an OEM Connexant DSL pile of filth. Neither would work at all with SIP or the IAX2 stuff. I have also had issues with iptables that I wish to never have to think about again! Since installing this Zyxel DSL router I have had pretty much no problems at all. The Bandwidth shaping is basic but consequently quite simple. It has SIP, FTP and h.323 as preconfigured profiles that require nothing more than a source and/or destination address, priority and amount of bandwidth to allocate. Other protocols require port number and protocol type as you'd expect. If configured to share root bandwidth among classes then it will happily allow browsing and leeching at full speed, but when you make a call there will be a near instant drop in download speeds elsewhere. I allocated 176kbps to port 4569 udp (IAX2) and found that using the voiptalk service was fine. I'm having a few ATM issues with our dsl here that didn’t help testing earlier today, but when the dsl is behaving itself, using the voip is certainly no different to using the pstn over asterisk. Both methods are using gsm as the default codec right now. There was the occasional defect in the voice I will admit, but that just the odd bit of packet loss I think. jd -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Adam Goryachev Sent: 07 September 2004 13:13 To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: RE: [Asterisk-Users] Lower cost router suitable for VOIP ?

Can you tell us more about this, specifically I am interested in it's capabilities to deal with different traffic scenarios while trying to hold a conversation. ie, conversation quality during large upload and during large download. Also, what is the reduction in overall download/upload speed while you are on a call, compared to while no call is in progress.
