VOIP phone system for 3 international offices required

[bobsa]

Archived from groups: comp.dcom.voice-over-ip (More info?)

Hi,

I am in the process of setting up three new offices located in Geneva,
Athens and Dubai. The Geneva office will be the primary location. In
addition we will have appromimately 4 home locations served by
broadband lines probably ADSL.

In order to provide inter office voice communications I wish to
install VOIP telephones and connections but they should also support
PSTN lines alterntive routing for local country calls.

There will intitially be 5 to 6 people in geneva and 2-3 in each other
office as it comes online. Future growth would probably not exceed 15
- 20 people total across all locations.

Ideally we'll utilise broadband ADSL in each location although a
leased line my be available for internet connection in Geneva. Are
fixed Ip addresses a mandatory requirement for the offices AND the
home users?

As this is a new company we have no legacy systems and are open to
make the maximum use of our technology investment.

I am very familiar with existing PABX technology but am new to the
VOIP concept. My back ground is networking \ computing in the
financial markets.

Quick overview of whats out there seems to point to Avaya IP office
but I've also come across some bad reports, can anyone recommend a
solution they are actually using and are very happy with. Support and
maintenance in all locations is obviously a key issue.

cheers

rob

The last I heard, Internet was regulated in UAE/Dubai and the government
was blocking all VoIP (RTP/SDP) ports coming from the outside. Has that
changed recently?

Check out the open source (GPL'ed) Asterisk PBX at
http://www.asterisk.org It'll give you what you're asking for, and much
much more!

I guess they wouldn't know what kind of traffic you had if you shoved it
through a VPN.

I'm using it (Avaya IPO) for exactly what you suggest (see locations
below), and it works *very* well. They also have a range of smaller IPO's
than can be used at the branch offices - use an IPO403 at the base and the
401 or small office edition at your smaller branches. Join them all up with
a VPN network - take a look at the Draytek Vigor 2600 routers for this -
and you have a very cheap and extremely reliable solution.

I'm using them in the USA, UK, Hungary and UAE (India next) - they're very
flexible.

Email me if you want more detailed info.
