<DIV><FONT face=Arial size=2>I am going to have max 4xE1 trunk to each direction

<DIV><FONT face=Arial size=2>Then woulde like to start with 2xE1 trunks.
Can you give me idea on configuration of libss7 and Asterisk?</FONT></DIV>

Asterisk will not function as a pure converter. All calls will<BR>need to be
switched, so if you intend on having 8 E1 coming from the<BR>EWSD, you will
need 16 E1 on Asterisk.<BR>That is doable using 2x8 E1 PCI xpress cards, or
a 4 PCI slot<BR>motherboard and 4 quad PCI E1 cards. You'll need to disable
echo<BR>canceling to avoid running out of cpu. And it will depend on the
volume<BR>of call setups. Your mileage will vary.<BR><BR>An EWSD should be
able to do EuroISDN anyways...<BR></BLOCKQUOTE></DIV><BR><BR>Alcatel's S12
(well, it was made long time ago and not by Alcatel) also should talk DSS1 aka
EuroISDN natively, but (as very many new designs) it may need extra license to
speak EuroISDN, so sometimes Asterisk is not expensive way to add
SS7/EuroISDN/SIP/IAX/H323 capability to existing pbx.<BR><BR>if running so
many E1, I whould recomend on seeing Sangoma's option for ss7box or Dicea's
solution to be able to have at least two servers, and cluster capability. And
i whould go not for one box, but many box, it would allow for some redundancy
(>=2 signaling links) and possibility to extend hardware to support more
E1s.<BR><BR>Regards,<BR><BR><BR>-- <BR>Krzysztof Drewicz<BR>+48 504 17 55
