I have a somewhat challenging config I am trying to simplify. I have a central IPO500v2 running 9.0.1. It has a SIP trunk (Line29) with about 100 URI's. Currently users dial outbound using different shortcodes depending on which number they want the called party to see. Some users might use 8 different outbound numbers depending on who they are calling so I can't base the CID on the SIP tab for the various users; also, many of the users are connected to separate IPO's in other cities/countries over H323 lines (non-SCN) so I don't get the full user information on every outbound call. In PRI I could just set the outbound CID in the ARS using NS1112223333. Is there any way to do that with SIP? Some way I can determine the CID based on the shortcode used instead of the user making the call?
