Garbled VoiP since churning to Exetel

Post by wroscoe » Sat Sep 22, 2007 10:16 pm

Hi, have had problems with garbled VoiP calls , can tell by dial tone breaking up and appears tied to uploading, have done port forwarding ( I think its right )have tried G729 and G711 , have set QOS on modem for priority for Mynetfone and throttle P2p etc , anything else I have missed ?
It was much better with Internode with my original settings that give problems with Exetel.. have also tried with firewall turned off..
thanks
Ross

Which Voip provider are you using? Can you do a traceroute to the sip server please?

The network connection looks fine. What sort of hardware are you using?

I run a Billion Bipac 7402VGO so i could help you in regards to your setup a lil more.

Have you made sure your running the latest firmware on the router? I found that a firmware upgrade can help with VoIP quality. Just keep on hand the emergency recovery firmware just in case the worst happens.

Now from memory the VGP has built in QoS settings for the built in VoIP, the same as the VGO (my work router) so you don't need to set any QoS rules for VoIP seperatley outside of the VoIP main setup.

I saw that you also said you have P2P rules...... no offence but even P2P rules in the Billions can't keep up with P2P clients and you will always have drop outs while running any P2P application unless your using a cisco router or *nix box.

Hi Spanner Man
I will check my firmware version , it has been a while and I remember having problems and going back to my old version... I will try it without the QOS and P2P settings but it still seemed to work with my old server.
Today on an incoming call it was badly broken up and then cleared and was perfect for the rest of the call???? will post results , thanks

Did factory reset and upgraded to latest firmware and re entered info less P2P and QOS settings with no result , tried Koala on other port with same problem... when with Internode I did not have this problem anywhere near as bad as with Exetel? am on 1500/256 plan which I thought was adequate , when I was on 512 with Internode it was a slight problem but when I upgraded to 1500 with them the Voip was really good.. any further suggestions ??
thanks

Don't use P2P while you want to use VoIP.
If you use VoIP as part of your buisness then get a dedicated ADSL line (recommend 512/512) with an el'chepo modem and an ATA device or something like the Netcomm V85.
Where i work we use v85's and don't have an issue with drop outs or bad phone calls.

The problem is you are downloading and a phone call comes in ! you have to immediately turn off the download and hope the caller hasn't given up , but now I find that I have this problem even when not downloading, just playing offline games, you can tell by listening to the dial tone , if it is breaking up you know you will have a bad call , in or out, and I did not have this problem with Internode before I churned to Exetel???.... help , the VoiP is driving me mad

By looking at your connection just now, i can see over 60 connections is opened for BitTorrent traffic. Even you stopped the download immediately when a call ring, it may only help you a little bit.

For further testing, i suggest you stop and shut down Bittorrent completely and make a call to see if the problem still. Alternatively, you may try changing the RTP port for your VOIP device to port 16384.

Hi Howard
Changed the port as suggested and will test futher.. I noticed something interesting in that if I am downloading on my desktop which is ethernet connected it does not seem to affect the VoiP but if downloading from notebook which is wireless connected it does , and am using Uniden cordless phones at 2.4 Ghz , could that cause problems? moved the modem as far away from the phone as possible as per another forum.
I wouldn't use the phone between midnight and 7-7.30 in the morning and would probably make only 2 or 3 calls a day and receive about the same so I don't no whether Fair Play would help much and I use Yahoo Messenger a fair bit as well.. thanks for your help
