Change INVITE package header - Conditional SIP profile

Hi all. Hi, I need someone that could give me a hand on solving this issue. Note: Need good knowledge of Cisco CUBE. My SIP provider is sending the INVITE package with wrong sip number as you can see bellow: Received: INVITE sip:765617@[login to view URL] SIP/2.0 (should be 0893540111) v:SIP/2.0/UDP [login to view URL];rport;branch=z9hG4bK7cvF8Zyv4U9yD Route:<sip:765617@[login to view URL]> Max-Forwards:65 f:<sip:0477770613@[login to view URL]>;tag=4rDev7jZe34jH t:<sip:0893540111@sip> i:9f452181-e17c-1239-eabe-00163ea67143 CSeq:31664763 INVITE I've been trying to apply Conditional SIP Profile to change this header with the TO number listed bellow. (DOC I've been using: [login to view URL] ) request INVITE sip-header SIP-Req-URI modify ".*@(.*)" "INVITE sip:\u01@\1" request INVITE sip-header To copy "sip:(.*)@" u01 I applied all changes listed for incoming calls but nothing happens. Is that anything missing in this DOC that I need to do? Is that a way I can list the content of the variable u01 so I can make sure I'm getting the right information? Thanks a lot
