<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>We’re using Asterisk with Digium TE110P card for the
PSTN E1 interface. Our PRI is enabled with detecting the
“connected-party-number” feature. When an OUTBOUND call is made to
a phone, the PRI will send back an ISDN messages containing the
“connected-number” and we can use that information to validate the
extension user is calling the party that he/she is authorized to. This is to
avoid the user letting know the receiver about the call and getting the
receiver to divert the phone to some other number.<o:p></o:p></span></font></p>
