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?
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:

Cheers, Daniel

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.
