The SIP message manipulations in the example above (contributing to typical topology
hiding) are as follows:
 Inbound source SIP URI user name from "7000" to "97000":
From:<sip:7000@10.2.2.6;user=phone;x=y;z=a>;tag=OlLAN;paramer1
=abe
to
From:
<sip:97000@IP_PBX;user=phone;x=y;z=a>;tag=OWan;paramer1=abe
 Source IP Group name (i.e., SIP URI host name) from "10.2.2.6" to "IP_PBX":
From:<sip:7000@10.2.2.6;user=phone;x=y;z=a>;tag=OlLAN;paramer1
=abe
to
From:
<sip:97000@IP_PBX;user=phone;x=y;z=a>;tag=OWan;paramer1=abe
 Inbound destination SIP URI user name from "1000" to 9721000":
