SIP Header manipulation

Question

I'm new to SIP and I have a problem that I think can be solved with an iRule.&nbsp;
&nbsp;Within my SIP header I need the CONTACT information to reflect the VIP address and not the private address of my SIP server. Currently the packet looks lie this: &nbsp;
&nbsp;--cut--&nbsp;
&nbsp;Contact: 
&nbsp;            Contact Binding: 
&nbsp;                URI: 
&nbsp;                    SIP contact address: sip:10.12.1.25&nbsp;
&nbsp;--cut--&nbsp;
&nbsp;I need it to look like this:&nbsp;
&nbsp;Contact:    (hiding complete address)
&nbsp;            Contact Binding: 
&nbsp;                URI: 
&nbsp;                    SIP contact address: sip:66.43.x.x&nbsp;&nbsp;

I should clarify, that when I said "if the string you want to replace is within the data of the packet (as opposed to the header)" I meant the payload of the TCP or UDP packet the SIP is being sent in.&nbsp;

I appreciate the response.&nbsp;
&nbsp;I've actually looked into a stream profile, but I don't see a way to apply a stream profile to UDP traffic. Is that possible?
