Sometimes, when I place a call, it redirects it to an internal extension. The only SIP message that I can see being sent when that happens is a 180 ringing with a p-asserted-identity in it. It only happens about 50% of the time. example: I dial 9.8001234567 and end up talking to someone at extension 3041. The Dialed Number Analyzer shows everything correctly. This SIP message is below. HELP!! please

My guess is that the call got hairpinned back to CUCM by the provider or CUBE. We need to see the full trace from CUBE to be sure. PAI is really just attempting to indicate who the call is actually alerting because the From and To headers cannot change after the INVITE message.
The fact that CUCM is sending a 180 RINGING message implies that it is processing an *incoming* call. This is reinforced by the headers because the From header is the SP SBC, the via header is CUBE, and the To header is CUCM. Inbound call!
Compare the Call-ID of the SIP INVITE CUCM first sends to CUBE for your outbound call to the one shown in this message. Are they different?
Run these if you want us to look deeper. If you have multiple calls going be certain to point out the calling/called number and the IPs if any differ from what you have called out above.

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
