Bogdan,

Thank you. I have looked at that module, but we are using 1.11. Is there no 
similar functionality in 1.11?

Unfortunately, removing and replacing the headers did not work when also using 
topology_hiding and uac_replace functions because they do not seem to be aware 
of the changed/expanded headers.

Hi Ben,

The OpenSIPS 2.1 has the compression module that is able to do that for you 
automatically:

Does anyone have any ideas about this?

The only thing I found was the txtops module. I tried using it to simply do a 
text replacement of the compact headers for the full headers:

replace("^c: ", "Content-Type: “);

But this doesn’t work when there are headers that OpenSIPS will replace like 
Via. When the message is sent, the text replacements end up in the wrong places 
as the new Via headers are not inserted in the same place the old ones were.

Would I have to actually remove the header (remove_hf), copy the content, and 
then replace it (append_hf)? What would be the best way to do that for any 
given header?

Is there a simple way to convert Compact headers to their full form and vice 
versa while processing a message? I haven’t found much mention of compact 
headers except that they are supported. I also saw the new compression module 
in 2.1, but we are using 1.11.
