Hey All,
I always have issues with substituting out header values. I’ve tried subst and subst_hf.
Here is the value that I want to change out:
Contact: <sip:52.41.52.34:5060;line=sr-h06Cy7RYRFkYacM0a7epa7sVa7sVRcNCW7IbaGZ9RGlC
<sip:52.41.52.34:5060;line=sr-h06Cy7RYRFkYacM0a7epa7sVa7sVRcNCW7IbaGZ9RGlC>>
And this is what I want it to be
Contact: <sip:1313717555@jump.dsiprouter.net
<sip:1313717555@jump.dsiprouter.net>;line=sr-h06Cy7RYRFkYacM0a7epa7sVa7sVRcNCW7IbaGZ9RGlC>
I’m using this
subst('/^Contact: <sip:(.*);(.*)>$/Contact:
<sip:1313717555@jump.dsiprouter.net;\2
<sip:1313717555@jump.dsiprouter.net;\2>>\r/ig’);
And it doesn’t work, but putting into a online regular expression tester it looks good as
shown below. Any ideas?

Hello,
what is the result? Do you use other functions that may change the
contact (like those from nathelper)?
Cheers,
Daniel

Hey Daniel,
I hope all is well!
I tried to make it super simple
The regular expression is this:
subst_hf("Contact", "/@.*>/@107.21.184.251>/", "a”);
The Contact looks like this
Contact: <sip:3135421245@10.0.0.140:53349;alias=98.209.240.245~53349~1>
It ends up like this (it concatenates it)
Contact:
<sip:3135421245@10.0.0.140:53349;alias=98.209.240.245~53349~1@107.21.184.251>
I really want this
Contact: <sip:3135421245@107.21.184.251>
I do call Nathelper functions in some cases. I can comment those out. What am I
missing?

Hello,
if you use more operations over the headers, they do not override each
other, they typically add to the content. Use msg_apply_changes()
between such operations, see:

Again, the question has to be asked: why do you want to rewrite the Contact header? And is
there a better way to accomplish what you are trying to accomplish?
Contact is constructed by the endpoints, not the proxy. Touching it is almost never a good
idea.
Where Contact is statefully rewritten by the topology hiding modules, touching it is also
not a good idea.
It’s just not a good idea.
