Implementation of split-header in HMR

(Doc ID 2417234.1)

Information in this document applies to any platform.

Goal

Issue : - HMR is not handling the History-info header properly.

history-info contained two URI's for example:

History-Info: "UCC CN"<sip:+abcdefghihjk@yyy.qqq.www.com;user=phone?Reason=SIP;text="Moved Temporarily";cause=302,Diversion;text="unconditional">;index=1;user-id="14389850075@oracle.xxx.com",<sip:+ncencejncej@yyy.qqq.www.com;user=phone;cause=302>;index=1.1

The following HMR was used to convert the ips/uri-host to the SIP interface ip-address.

Since the history-info contained two URI as above, the 2nd URI was not converted and it was passed as such and hence exposing the IP from the trusted side to the un-trusted.
