asterisk users - Jul 2005 - Need to start from somewhere

Hello all,

since we are sitated in Serbia and Montenegro and Linux, VoIP, Open Source and
ECONOMY here are in the diapers. We are traying to start  "Asterisk
implementation project" and make it available to small people (in small
companies,hotels,homes etc). The reason is that here we have "exclusive
distributors" of PBX equipment (Panasonic, Ericsson,Cisco,3com etc.) in
pocket and cicuite comutation, and for them sky is the limit when the price of
equipment is in question , they have money for orders and sell equipment at
much,much  higher price if you compare it with EU prices or USA prices. And
people like we have needs and do not have that much money, so we are traing to
make alternative and hope it will be better ...

SORRY FOR MY LONG  PRELUDE ( we respect kbps)

QUESTIONS:

  1.. What we need to know about our LOCAL PSTN telco (digital) lines to be
shure in our hardware choise (voltage, current etc.)?
  2.. We need 4 PSTN line system which can recive and make calls (on all four
lines) from and to the local VoIP network, hardware sugestions PLEASE?
  3.. Can four Digium Wildcard X100P make that happen and is that stabile in
production?- we need to make working sistem and also cheap system?
We are still learning Asterisk so sorry for this beginner mail.

Thanks to all

Darko

*IF* they are EuroISDN, then they are standardized, at least at the
physical layer, and you shouldn't worry about it.  I'm quite confident
that they are, since the national operator must have bought standard
equipment for the central offices.

You could use one Digium TDM04B, which is a much better idea than four
separate cards.  Otherwise, you could look for external adapters, but
I'm not able to tell you which are both cheap and reliable!

Bye,
