3 Mbps cable internet is good enough for freephoneline?
i want to use FPL, but i have some question regarding the internet speed as below:
1) is 3 Mbps (download speed) & 256 Kbps (upload speed) good enough for freephoneline or i have to use 18 Mbps (download speed) & 512 Kbps (upload speed) for freephoneline ?
2) is anyone useing 3m cable internet with free phoneline right now? what is the sound qulity?
thanks

Re: 3 Mbps cable internet is good enough for freephoneline?
The softphone app is free to download -- and an account costs you NOTHING to set up other than time. There are so many variables in your setup, such as ping, jitter, firewall and other stuff that it is impossible to say yes or no.
Download the app, see if it goes or not! Most you will lose is 10-15 mins of your time.
For the record, I am using a WIFI datastick (WIND of all things!!!) and I get acceptable results on dialed out calls -- incoming ones are 50/50, but I can always call back. I lose some audio upfront at the start of the call, but as it progresses it gets better. There are still times when it gets choppy if the connection "jittters" but overall it is fairly stable.
I am not sure what kind of actual speeds I am getting ...
PINGTEST.NET gives
"B" MOS: 4.35
ping 104ms
jitter 6ms
SPEEDTEST.NET gives
ping 163ms
DL 2.90 Mbps
UL 0.33 Mbps

Re: 3 Mbps cable internet is good enough for freephoneline?
If you use an ATA with built-in router like the SPAx102 and that is connected directly to your stand-alone modem, you should be good with that speed assuming that your internet connection has low latency and jitter (you can use pingtest.net to find out). You can then connect a router to your ATA. This set up allows you to have all the needed bandwidth for your VOIP before anything else on your network for a near problem-free VOIP experience. You don't even need to forward ports...caveat is, these ATA/routers eat up quite a bit of your bandwidth due to their built-in VOIP QoS.excell99 wrote:i want to use FPL, but i have some question regarding the internet speed as below:

I was using the 256Kbps upload speed (with a 7Mbps download which does not matter much in VOIP...it is the lower speed that matters) when I first dipped into VOIP in early 2005 using a DVG-1120M (it was a MeGaCo ATA, not SIP) and I had no problem with voice quality. So yes, 3Mbps download and 256Kbps upload service is good enough.

Re: 3 Mbps cable internet is good enough for freephoneline?
Nominally 3 Mbps (download speed) & 256 Kbps (upload speed) should be good enough for Fongo but it is the 256 Kbps (upload speed) that can be iffy. Any significant uploads on your network may spoil your calls. If the real speed is 256 Kbits/sec for upload and nothing else uses the network at the same time for upload then you should be OK. With some SIP providers you can use low bandwidth codecs that can help but Fongo does not offer them and the sound is less good. I used 1.2 Gbits/sec down and 0.5 Gbit/sec upload for voip for years with excellent results.excell99 wrote:i want to use FPL, but i have some question regarding the internet speed as below:

Re: 3 Mbps cable internet is good enough for freephoneline?
thank you all.
it seem that a good router with QoS is critical for FPL.
i just quickly check the futureshop and find this one:
http://www.futureshop.ca/en-CA/product/ ... ea3a6een02
1)is anyone using D-Link Wireless N 300 Gigabit Router (DIR-651) for FPL?
2)is it good one or you hav any other recommendation?
thanks

Re: 3 Mbps cable internet is good enough for freephoneline?
Aside from clock frequency, RAM and flash memories, gigabit ports and wireless radio specs, I consider a home router good if it can be flashed with 3rd party software (Tomato, DD-WRT, etc.)...but that's just me!
I don't see that DIR-651 meets my criteria.

Re: 3 Mbps cable internet is good enough for freephoneline?
Even 128kbps each direction would run the service. All it matters are three things
1. latency to sip server
2. jitter
3. packet loss
Your maximum bandwidth does not have definite relationship to factors above. I have 3M/512k and 15M/768k. Both are less than km apart and gives roughly same quality.
If you are on 128kbps, you will not have much room for anything else when you are on call. You have significant likelihood of affecting phone conversation as you have very little bandwidth remaining.

Re: 3 Mbps cable internet is good enough for freephoneline?
As the others here have stated, a lot depends on what you are doing on your internet at the time you are on a call ... for me, I make sure that i bail out on everything but the VOIP and whatever else is critical (like a statically open web page or what not) and try not to surf or do anything other than maybe compose an email or two while I am on a call. This is one reason that INCOMING calls can be troublesome, as I scramble to shut down anything that is eating bandwidth.
So the OTHER traffic and the quality of your service really matter --- for example if you share wifi in the house with another suite, you can expect all kinds of issues. If you use torrents a lot, same thing. But if when you are using VOIP you tend to single-task it, you should be okay.

Re: 3 Mbps cable internet is good enough for freephoneline?
If I were to buy again based on my needs, I would still buy the Netgear WNR3500L...but this time the V2. Other than the upgraded 128MB RAM + 128 MB flash, it has the same specs as the V1 that I have. The V1 can be had for ~$67 from Best Buy, or the V2 from Amazon.ca for the same amount...$67 with free shipping.excell99 wrote:i find another Netgear Wireless N Router (WNR2000-200PAS) in futureshop.

Re: 3 Mbps cable internet is good enough for freephoneline?
QoS is depending more on stability than bandwith, for an instance, you have:
An old 56kb dial-up connection but your FPL ATA is the only device;
An Extreme Highspeed Internet connection but there are a few devices sharing the service, some playing online games and some downloading stuffs;
As to QoS of FPL under these 2 cases, Dial-up wins!

Re: 3 Mbps cable internet is good enough for freephoneline?
Okay, let's not create more confusion with VOIP than there is. The fact is...firstly, you need to have enough bandwidth to support the codec that your VOIP connection is using.j8van wrote:QoS is depending more on stability than bandwith, for an instance, you have:

You can have a 56kbps connection with less than 3ms latency and jitter, however it is not enough to support the PCMU codec which BTW is used by FPL.
On a high-speed high-bandwidth connection (with <50ms latency and <10ms jitter like most Rogers connections are) with a device supporting QOS that is properly implemented, bandwidth usage can be prioritized for VOIP even with literally a hundred simultaneous torrents running, and will beat the 56kbps hands down.
So, now draw your conclusions...ugh, I think I already did it for you.

All right I can answer this for you no problem cause my older brother use Linksys ATA voip and the router is Linksys WRT54G flashed with DD-WRT firmware
His internet speed is 3Mbps and he got great audio on the phone

Re: 3 Mbps cable internet is good enough for freephoneline?
That is true for the download speed but it is the upload speed that really matters as it is generally much lower and around 0.5 Mbits/sec. 0.25 Mbits/sec is more than enough for SIP/voip as long as not too many other things are using upload bandwidth. If you can use the low bandwidth audio codecs then even dialup can give reasonable sound (used it for years myself for calls to the UK).

Re: 3 Mbps cable internet is good enough for freephoneline?
The WNR3500L is a good router, especially with the DD WRT firmware. I am not familiar with the Amped router. Pay no attention to the power of a router. Most times it does not translate to much in real life situation. You will get just as good results with a cheap router like this, when flashed to DD-WRT. I should add the DD-WRT does QOS if that is your thing. http://www.futureshop.ca/en-CA/product/ ... 75bb6een02excell99 wrote:I narrowed down to two router. which one do you think is better for FPL?

Re: 3 Mbps cable internet is good enough for freephoneline?
Reading this topic hurt my head, so much bickering back and forth.
Stick to the facts, read what's been said, don't repeat facts already evidenced in the prior knowledge unless as a re-cap whereby you will include ALL facts that are previously evidenced.
Fact:
Jitter is more important than bandwidth or latency
Fact:
PCMU and PCMA (g.711a/u) also known as U-law and A-law codec perform 8kHz sampling at a rate of 8b/sample (64kbps)
Fact:
VoIP is a symmetrical protocol (meaning it requires 64kbps in each direction)
Fact:
Many routers implement a poor or broken version of 802.1p (QoS standard protocol)
Fact:
DD-WRT and various other open source based firmware replacements have functioning QoS protocol stacks
Fact:
QoS can be difficult to understand how to implement correctly, and there are several on the forum here who can help you (Myself included) to come up with the correct QoS for you.
Fact:
802.1q (VLAN) protocol can be used in addition to standard QoS to prioritize bandwidth.
Fact:
When prioritizing bandwidth you must consider not only the amount of bandwidth required, but what order packets are to be sorted in. (VoIP should be given the highest level of order to ensure lowest possible jitter and latency) Both are affected depending upon traffic on the network.
Fact:
While high order must be ensured 64kbps is all that is required for the data (add overhead for ethernet frames/TCP/IP encapsulation) and remember that 802.1q (VLAN) includes 4bytes of it's own, you end up needing just a few bytes extra. Try to dedicate 72kbps to the VoIP device. (I try to keep everything in multiples of 8 for binary data 8b=1B)
Fact:
Torrents are notoriously difficult to control with QoS/Packetflow and firewalls from the router, try to ensure that torrent programs are individually set to use a low upload bandwidth. (You have 256 available, make sure they're set to <128)
Aside:
VoIP over Dial-up is entirely possible with some of the lower-bandwidth codecs such as GSM requiring a mere 6.5-13kbps. (This is why cell-phone call quality sucks, combined with the poor latency and jitter of mid-long range wireless communications)

While high order must be ensured 64kbps is all that is required for the data (add overhead for ethernet frames/TCP/IP encapsulation) and remember that 802.1q (VLAN) includes 4bytes of it's own, you end up needing just a few bytes extra. Try to dedicate 72kbps to the VoIP device. (I try to keep everything in multiples of 8 for binary data 8b=1B)
Fact:
Torrents are notoriously difficult to control with QoS/Packetflow and firewalls from the router, try to ensure that torrent programs are individually set to use a low upload bandwidth. (You have 256 available, make sure they're set to <128)
Aside:
VoIP over Dial-up is entirely possible with some of the lower-bandwidth codecs such as GSM requiring a mere 6.5-13kbps. (This is why cell-phone call quality sucks, combined with the poor latency and jitter of mid-long range wireless communications)

Re: 3 Mbps cable internet is good enough for freephoneline?
That's one reason we missed him so much!!
