Mac Forum / Country Specific / UK Mac Group / August 2007Got 2mins to do a traceroute for me?
If anyone has a few moments to spare, they could help me to try and diagnose the shitty VoIP performance I am getting from Gradwell. Do a traceroute to: lon-pbx-11.gradwell.net Tell me how many hops it takes and which ISP you use. Really like to here from anyone using Zen or other "business" orientated ISPs. At work BT are providing the ADSL VoIP circuit: it takes 17 hops to get to the destination. At home I use Eclipe and it takes 6. With a UDP protocol I assume the more hops the more places a packet can get lost? Maddeningly however, Work/BT scores a near perfect 4.4 on testyourvoip.com whereas Home/Eclipse gets a crappy 3.1. > Do a traceroute to: > > lon-pbx-11.gradwell.net > > Tell me how many hops it takes and which ISP you use.

Generally, would you expect that the more routers you put between you and it, the more likely you'll get excessive packet loss with a UDP based service like VoIP?

My TCP/IP is pretty cack. Some ISPs had a habit of discarding UDP packets, probably thinking that since they were unreliable by definition, no one should be surprised to lose a few. Our company's old VPN was UDP-based :-( Try your traceroute tests using different protocols - Tiger's traceroute lets you switch between UDP, TCP, GRE and ICMP.

Doing a traceroute from their network? Or you > have a Co-located box? No, probably on an ISP which responds to traceroute traffic on behalf of the remote server. If you look too carefully at the Oxford Uni network, you'll see that all the computers are plugged into the same switch. A few years ago, that switch was in Reading. Bonge Boo <bingbong@spamcop.net>: [...] >> Looks pretty good to me! > > Erm.. Gradwell employee? Doing a traceroute from their network? Or you > have a Co-located box? Yes to the second: that was a traceroute from newred.gradwell.net. You'd rather expect it to be a short hopping distance to lon-pbx-11.gradwell.net from there, really. I was just pulling your leg. :) >> To be a little more helpful, it's 13 from Virgin Media. > [quoted text clipped - 3 lines] > and it, the more likely you'll get excessive packet loss with a UDP > based service like VoIP? My TCP/IP is pretty cack. UDP is not TCP/IP, and you're not sending packets with UDP, you're sending datagrams (hence the name). Otherwise that sounds like a reasonable assumption, yes. On the other hand, the whole point of a streaming protocol like VoIP is that it shouldn't matter if some of your datagrams are getting lost. If you need guarantees of delivery and that things are in the right order (which you shouldn't for a real-time, streaming application), then UDP is the wrong choice. b.

Depending on where you are (I'm in SE London) ADSL is a thoroughly broken protocol, totally unsuited to modern, high useage conditions. If you're in a light useage area with little contention (which is effectively what ADSLMax was designed for- i.e normal useage three years ago) or you don't mind having 3.5Mbps real download speeds after midnight, and more like 1Mbps in the working day, then you'll be fine. For me, right now, that's fine. Will it be so for you? Whatever anybody says about Virgin/NTL cable, my son in law (also in SE London) switched to them and gets a totally regular 3-4Mbps, any time.

Will it be so for you? I won't be using it during the working day (I'll be working) and that sort of speed should be fine for me in the evenings. I currently have the 4Mb Virgin service, which is more than adequate in terms of speed -- it took me a few days to notice when, after some serious problems, they downgraded me (without saying, or changing the billing) to the 2Mb service. Obviously it would be nice if my `up to 24Mb' service did operate at anything near that speed (or even a third of it), but there we go. > Whatever anybody says about Virgin/NTL cable, my son in law (also in SE > London) switched to them and gets a totally regular 3-4Mbps, any time. I can't face being with Virgin again, I really can't. I would accept a slightly slower service that works reliably and is operated by people who speak the same language as I do. No other company has ever made me, as a customer, feel so powerless or so uncontrollably angry. b. Signature<bas@bas.me.uk> <URL:http://bas.me.uk/> `Imagine the world's leaders on pills.

Still getting no closer to getting the issue resolved. We have frankly awful call quality, one-sided aduio, echoes, etc. They want me to make some firewall changes that I'm not even sure this Netgear can do (turning off the inbound firewall rule). We have a bunch of static IPs that could be used if I turn of the NAT router. Humm... I'm begining to think VoIP was a bad idea. >Still getting no closer to getting the issue resolved.

I think that's because my ADSL line runs in interleave rather than fast mode. I have two Gradwell VoIP lines, single line rather than centrex. I used to have ISDN 2 and ported two numbers from my block of ten to these VoIP lines. I use a Siemens S450IP VoIP DECT system, and it all works well. It took a while to get to that state. Firewall settings are important and weren't very well documented on the Gradwell site (especially for ported numbers, which seem to use a different IP range at their end). I don't use NAT, and use a Cisco 837 router. It may be worth your while trying to borrow something like an 837 to see if that might improve things. The S450IP has a few problems, mainly that it can't handle two calls on one SIP account. I tried Asterisk (on a Mac mini) between it and Gradwell to fix that but 1.4.x had problems with the ported number VoIP kit at the gradwell end and I haven't tried 1.2.x yet. I've also used X-Lite on an iMac and that works fine. The failures I got were calls not working at all. The only time I've had audio quality problems was when BT capped my ADSL rate at 512kb/s for a few days. Normally I get about 2-3Mb/s and call quality remains good even if I'm saturating the ADSL line with a huge download. SignaturePeter Ilieve peter@aldie.co.uk |
