terrible call quality

Hello,
I've just tried calling someone with PlusTalk, but the sound quality was terrible. On the other end they struggled to hear me over bad crackling, and to me the call sounded muffled, like someone talking through a duvet. In fact, no-way near as good as using voice conversations over MSN Messenger.

Is this just me? If so, I'll play around with my settings and try again. Otherwise, I can't see it beating a normal phone if the quality is much worse.

David.

Hi,

If this was just one call, I'd suggest trying a second call just to ensure that it wasn't a one off issue. If its still not very good quality, then obviously check your settings and so on. You might also wish to try calling the echo test number on 7000 to see what quality between your machine and our servers is like.

As for quality my own experiences have been fairly good, though I've only made a couple of calls myself.

I seem to be having the same problem all the time, i have phone a few people, and people are saying i sound miles away.

Also has anyone had problems with setting up the local rate number.

I found the call quality to be iffy when using X-Lite but I have found it has improved quite a bit since I've started using my ATA and handset.

Hi,

I gave up with PlusTalk & X-Lite pretty swiftly as the call quality was utterly aweful. It was un-useble frankly and as I'm NOT desperate for the service I'll be sticking to my BT service.

There are loads of things to take infto consideration with doing voip.

Our infrastructure here, we offer voip as a service, but as a result of this we have had to do the following:

upgrade out network core from atm 622 to 10 gigabit
create multi vlans to accodate this specific traffic
route the vlans to the appropiate networks which have qos and jitter buffering technologies available to manage this traffic.

it works fine now, but the traffic is dedicated and managed, and assigned the right priorities, as well as using the appropiate network technology - imagine doing this on the internet!

Hi,

Sorry!! you may have shed loads of new technology installed but the bottom line for me is 1) can I make & receive a call as easily as BT 2) is the call quality as good as a normal BT landline.

The answer is no! on both counts, so it aint for me mate!! The call quality was pants frankly!! IMO

To be fair, the free version of X-Lite doesn't support the codecs necessary to do VoIP well. It only supports A-law, u-law and GSM codecs, all of which do not tolerate packet-loss & jitter. As a quick fix, try disabling the GSM codec - just click on the "GSM" in the display and it will turn grey. Then when you place a call, X-lite will only advertise the A-law and u-law codecs - this may get it sounding a _bit_ better. But, beware, these codecs are the most inefficient around (at 64kbits/sec) and really don't do well with packet loss etc.

If you want better quality, you'll have to pay! I use a Vigor 2500V ADSL router. This has a built in phone port, and, most importantly, it supports the G.729 and G.726 codecs which are much better suited to VoIP. It's simple to set-up, compatible with F9 and PlusTalk and it means you can still receive VoIP calls even when your PC is off. The phone will ring when a normal PSTN call comes in, and will also allow you to place normal PSTN calls too - generally a much better solution than a softphone on your PC.

Hi there,

I too am suffering from poor call quality.

I have tried the u-Law/A-Law settings on the X-Lite and it was even worse than the GSM codec.

Also a couple of nights ago, calls kept failing (I was attempting to call my own BT line) and I was getting some 'female' vioce telling me something, the problem was the audio was all distorted so there was no way I could understand what she was saying.

That said, calls seem to work reasonably OK some of the time. We have been told at the dialled end that our voice breaks up occasionally, and the received audio on the X-Lite sometimes goes into distortion (very noticable when getting ring tone from the far end).

I am on the verge of cancelling the PlusTalk account because as other have said the same thing - the call quality isn't good enough. This isn't a VoIP issue as such as it can sound very good if the network isn't dropping packets. We have a VoIP PABX at work and you can't tell the difference.

Possibly the problem lies with the VoIP<->POTS gateway, I don't know anybody else who is on PlusTalk to eliminate this and do a SIP<->SIP call.

Just for interest I tried Skype last night - the call quality is much better!

The network changes F9 have applied during the week appear to have fixed the problems with the call quality for me Cheesy

Hi Again,

Firstly, VoIP is still an emerging technology here within the UK as far as I can see. OK! technically its been around for a while now but its only within the last 12 months that its started to be made availble to the domestic internet user market via ISP's and telecoms companies. All of them VERY keen to add your voice calls to their profit margins of course!!

**IMO the call quality and ease of use issues have to be ironed out before I will use the service. Its has to be as good as a normal BT voice calls & its has to be as quick & as easy to use as a normal BT landline otherwise I cannot see it taking off.

**WatchDog on BBC1 recently reviewed VoIP services and TBH non of them was thrilling or came out as attractive options. Skype got good press as did BT's own VoIP service (but you had to pay for the BT service I beleive?).

**PlusTalk was frankly a let down (all furcoat and no knickers TBH Shockedops: , great come on, terrible tease but terrible let down). Wont be cancelling my BT voice calls in a hurry yet then!! :roll:

Hi, I use Voip as my business line in to my house using Sipgate, got a normal phone pluged up to the back of my voical adpater, i dont seem to find a problem with it until i phone some else with a voip on a wireless network, thats a bit rubbish, but apart from that, its cool! Cheesy

I tried plustalk for about 1 month before buying my other stuff, and i just could not get it to work right, and when i did, found the quaility very poor.

Hi J,

Enough said then mate, I think that proves my point !! PlusTalk has some distance to go before its a viable useable service, its just NOT up to it as yet.

Hi everyone,
I can't believe so many people replied on this thread! Haven't been looking at it since October! Anyway, I have just tried it again with a friend and we soon gave up. It's true that it is marginally better, but still not a patch on the normal phone line.

I understand that it may be improved further by splashing out on specialised routers etc., but there's no way I'm spending a penny if I'm not assured it will work.

I agree with Ivan, Plustalk may be cheap, but it needs some substantial improvement before I'm tempted to make a switch.

David.
