Need Advice for VoIP hardware setup

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

Hi,

I was wondering about a VoIP hardware setup that we can setup in
our organization. The Organization set up is as follows.

1: Different Branches within on city and also other cities.
2: Within a single city, We have DSL Link at each location from
single ISP.
3: Across the city the ISP are changed.

We have independent PABXs at each location. What we want is a solution
that we can integrate with the existing PABXs. Using the VoIP Hardware
we should be able to use the normal telephone sets and make call within
the organization (in the same city or inter-city call).

Please advice me any good and inexpensive solution.

Take Care

Fakhar

Depends on their quality expectations, the quality of their DSL link,
surplus bandwidth available, and the number of simultaneous calls, I guess.

If they have enough capacity and just a few calls at once, it shouldn't be a
problem. Heck, I have a cheap 1024/384 DSL link in a country 300ms away from
my SIP proxy and I can push two calls through at once without any sound
quality problems at all.
