Modifying an incoming SIP INVITE message truncate number
I'm trying to write sip profile that truncates the 10-digit Diversion number dow to the last 4-digits and re-writes that number back into the Diversion header, but I'm not very succesful. I've written may copy and writes to different headers, but never had a need to first truncate a part of the header and re-write. For example (IP addresses changed for privacy):
The parenthesis around it simply means "remember what you matched." This is because the modify command, requires that we replace whatever we matched with something else, and we want to be able to reference something we matched; in this case, the last 4 digits.
Lastly, much like the prefix matching, we match postfix, and stipulate that the number should be followed by an at sign (@).
Ok, this is actually the last part, we have to do the replace, on what we matched. So we specify our prefix and postfix yet again, followed by recalling what we told the profile to remember about our match.

(+5) Anthony. To add to this, Inbound SIP profile manipulation was added starting IOS 15.4(2) T and XE 3.12S. If you are not on the minimum code, you cannot configure inbound SIP profile. If this is a CUBE, you can use outbound profiling without issues and without the need to upgrade code.
