Re: [asterisk-biz] VoIP Provider Matrix of rates/services

sam,
thanks for the note.  your are right, the key is to have good codec, bandwidth, and routing with no packet loss... still a tall order over inet.

Hello Dave,

In VoIP I can actually you tell that 100ms of delay is nothing even 200ms is quite acceptable. As long as you are using a good codec ie ulaw / alaw + have sufficient bandwidth + no pocket loss and etc. then you can still achieve high quality calls out of it.

You see if you dial a international number like oversea call with your local PSTN provider, you will not notice much decrease in quality even though the other side of the person may be somewhere half way around the world..

moshe, nitzan,
thanks for the comments...  didn't think it even possible with up to 200ms delay.  yes, there are many factors in quality of call...    I guess that is why I wanted to nail down the quality parameters so I knew what to ask for in a provider but at a deeper level....    perhaps it is too complicated an issue to address right now with the fact being that your voice packets can transverse the country of origin a few times and hit multiple providers before it gets to the PSTN.  guess I'll have to wait for a more complete matrix and target on rates only right now.
thanks for your input.

Actually in the countries I work in (we have servers in 3 countries, 

including the one you mention) the norm is 8ms - 20ms. However

we do have customers farther away and they go up to 200 and sometimes 

even more.

All I am saying is that latency is only one factor, and there are others 

such as packet loss, jitter etc.

Not to mention termination where results can be all over the ballpark no 

matter how close "your provider" is to you...

In your country, the current norm is probably around 200 ms. But since

that is the case, I imagine ISPs are more dedicated to eliminating lost

packets, etc. so the service does not suffer except for (very) slight

delays. Last time I spoke to my father (same country) via VoIP, he

couldn't notice a delay at all on his side. I noticed it, but it wasn't

significant.

In the US though- service from a 200 ms provider, or a 40 ms provider,

makes a HUGE difference in voice quality, in my experience.

  Dave,

I can comment on 100ms delay remark, that it is not always true. Wehave

call center customers who have 180 - 220ms  and are happy.

There are other factors besides latency which can effect quality, so

Ido not  completely agree with your comment

I already compiled a list from website info... not totally

completethough.  all public info w/o calls to providers...   

really, I wanted the providers to update the matrix themselves over

theweb so they could control the information.. the biggest reason I

don'tthink they should have a problem with it is they all don't cover

theentire world or the US either.  some servers have too much delay,

over100ms, so any customers they have outside their 'local network

area'would get poor service and they shouldn't want to waste their time

ifthey can't provide the service to those customers...  knowing that

infotidbit saves face and bad will...  helps the community too!

any additional thoughts?

The best would be in the spirit of web 2.0  - a list of providers,

which would have data, that partially be filled in by the

companies(like voip-info has), but also have an active user rating

It is a good idea, and I would love to have a list of

wholesaleproviders readily available so I can pick and choose the ones

I likemost according to price & support criteria.The problems with this

are, well, half the providers I've contacted inthe past request that

you sign a non-disclosure agreement, and theother half act like their

rates a big secret, and only disclose themupon request. I think this

has a lot to do with providers being worriedabout competition, but in

the end if you provide overpriced servicewith bad quality/support

customers WILL find someone better whether youpublish your rates or

not.You could always start a matrix by yourself... the only problem

withthis is that you won't be able to publish providers who require

anon-disclosure agreement. But then again- 9 times out of 10 those

arebad quality and overpriced. I would avoid those anyway despite

any(false) promises they might make.  -- Nitzan--- dave cantera
