The x100p card was designed to work with the US telephone standards
(600 ohm line impedence) and will likely cause echo if used in other
countries. I don't have a clue whether Egypt telephone standards are
the same as the US; probably not.

The TDM04B card (four fxo ports) was designed to work with telephone
standards in most countries. You should consider using that card instead
and you will find it at www.digium.com web site. Each TDM card can have
up to four daughter modules on it, and each module can be either a
fxs module (for connecting to standard telephones) or fxo (for connection
to telephone lines that come from your telephone company). To order a
card with only one line, the part number would be TDM01B.

A Linux PC with a TDM card installed and asterisk code will work just
fine for small installations. Nothing else required.
