[OpenSIPS-Users] Compact/Full Headers

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.
