VoIP voice quality differences

Vendome — Tue, 09 Feb 2010 11:52:15 +0000

I am trying to commission a network of Cisco Call Manager Express systems with (mainly) Cisco 521 phones connected to a private IP network for a corporate client. Prior to the “proper” solution being introduced a temporary solution using Asterisk with Grandstream GX-2000 phones was installed to provide limited service. Both solutions are using SIP between the sites, G729 codecs and run over the same IP network. The IP network is satellite so the latency is large and there is quite a lot of jitter.

My problem is that even though the systems are connected to the same network, the Asterisk/Grandstream solution sounds so much better than the Cisco/Cisco solution. Heavily used satellite IP networks are never going to provide perfect voice quality.

Is this just the way it is? If so how to I explain it to the client?

Thanks

Equipments needed for VoiP Business??

Shoreseattle — Sat, 28 Nov 2009 22:19:25 +0000

Hello,

My name is Adam,
I am interested in building a business that would allow customers to make an
unlimited international calling to a chosen country (cellphones and
landlines)..

Basically, I want to provide an unlimited calling to certain countries with a
monthly flat fee. customers will be able to get their
international number switched by My company to a local “DID”
number that will connect them to their destination abroad. No known
telephone features will be added to the main service of the company. “Just
Unlimited international calls to a certain country that I am currently trying
to negotiate rates with, for call terminations (cellphones & landlines).

I
do not have a business and wanted to lower cost of my phone bill. The
Business is, providing customers unlimited calls to the country of
their choice.

There are to Companies that currently offer unlimited calls to Morocco,
Tunisia, and Algeria using the same VoiP technology. Please feel free to
check them out.

www.kleema.com

www.amanatel.com

Here is how their services work:

1- Sign up and pay the service fee for the unlimited calling towards one of the
mentioned countries.

2- Register the phone number you’re calling from, so they can connect the
call.

3- The company will change your international number to a local one, they
charge per telephone numbers. the person you’ll be calling has to have a
phone from a carrier that the company had negotiated rates with.

4- After the transaction goes through, you ‘ll be emailed local numbers for
each international number you provided, then their system connects you.

Any suggestions on how to approach this ?

What are the equipments I need to start the business? And
what is the ballpark cost for that?

Sincerely,

Adam. M

UC solutions: Show and tell

JennyMack — Wed, 17 Jun 2009 21:43:51 +0000

As Tony Bradley frequently emphasizes on his blog Unified Communications: Click to Talk, there are many benefits, cost and otherwise, to implementing UC solutions within your organization. I want to know — are you using UC? What product(s)? How has your experience been, and why did you make the switch? Was it mainly cost-driven, or were there other reasons?

I’m searching for a large scale SIP based analog/IP convertor

Johan Leroy — Wed, 09 Jul 2008 08:21:21 +0000

We are deploying a large scale VoIP system (+/- 5000 phones), based on Asterisk and SIP.
In some of our warehouses we want to keep using the existing analog phones.
We have 2 options (that we know of) to connect these analog phones to our VoIP system:
1) Linksys SPA2102 analog/IP convertor
Advantage: You can connect it to your IP LAN.
Disadvantage: Only 2 analog phone connections.
If you need to connect 50 analog phones, you require 25 switchports,
25 power supplies, short: a whole bunch of cables in your wiring.
2) Rhino Channelbank
Advantage: 1 machine (1 power supply) with 25 analog phone connections.
Disadvantage: No LAN connection. You have to connect this Channelbank to your
VoIP server/gateway using a PRI connection.
If you need to connect 50 analog phones, you need a VoIP gateway
with 2 PRI interfaces, near to your Channelbanks.

An ideal solution would be to have an ‘oversized’ Linksys Sipura box with 25 (or more) analog connections and with one LAN connection.
Does anybody know whether such devices exist?
