Thank you Uriel and Alex for the helpful tips, I changed it like how it was suggested by you, and works like a charm!

Thanks,

Dmitri

Or "100rel," if there are other values.

Dmitri,

I had to do this to workaround some Huawei bug.

You have to check for supported and then replace ´100rel;' and then '100rel' just in the case Alex mentioned.

You can forward a message with an empty 'Supported:' but you cannot send one with a ';' at last.

Check if tha works.

   I suppose it could, but it would not be SIP-compliant to have a
   blank value for the Supported: header if 100rel is the only thing in
   there.

       Thank you for your reply Alex!

       This cannot be done like this?

              if(is_present_hf("Supported"))
              {
                      replace_all("100rel", "");

              }

       I mean instead of using the subst() function what you mentioned.

          This can certainly be done using the subst() function in textops,
          but it is not proper for a proxy to make such manipulations.

              Hello,

              Is there a way to remove 100rel from Supported header (only
              this, and keep the others) by Kamailio?
              I am using Kamailio 1.5.1 notls.

              Kind regards,
              Dmitri
