<DIV> </DIV>
<DIV>I'm being requested to deploy an IVR service using SS7. </DIV>
<DIV>I've deployed Asterisk before using ISDN connection, but never with SS7.</DIV>
<DIV>Can anyone explain me the different between using ISDN and SS7 ? What need I do now to change to use SS7 ?.</DIV>
<DIV> </DIV>
<DIV>Many thanks,</DIV>
