<TITLE>AS5xx0: SS7 and SIP?</TITLE>
</HEAD>
<BODY>
<!-- Converted from text/plain format -->
<P><FONT SIZE=2>We currently use Asterisk to provide a SIP-to-PSTN service. The actual conversion takes place somewhere in a softswitch owned by our SIP-to-PSTN provider, where we have an SS7 link. We would like to do that conversion ourselves.</FONT></P>
<P><FONT SIZE=2>Is it possible to replace a softswitch with a Cisco AS5xx0 only (ie. AS5300, 5350, 5400), or is a *real* softswitch (ie. Cisco PGW2200) needed? Does anyone have any experience with an Asterisk--CiscoAS5xx0--SS7 configuration? As far as I know, Asterisk--CiscoAS5xx0--PRI works, but I couldn't find anything about SS7.</FONT></P>
<P><FONT SIZE=2>Thank you</FONT>
