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

Sat Feb 16 12:39:44 CST 2008

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
