Hello,
are the other headers (Via, Record-Route) handled by the topos module for OPTIONS request? Is only Contact header left?
Regarding topoh: there can be some enhancements to try to shorten the size of those values, from what I know, short text compressing can get 20-30% compression rate, but not always and I am not sure will actually help with those SBCes. Have you able to figure out the size of the header values when they fail to handle the sip messages?
On the other hand, I am eager to see how those SBC are going to do when STIR/SHAKEN is added (soon by US/North America carriers), the Identity header is quite large...
Cheers, Daniel

Hello, I just realisied I made a mistake and send this reply to the wrong mail address. The OPTIONS are keepalive-request and out-of-dialog. So topos is not able to manage these? I also tried topoh. Topoh was able to mask the contact header even in out-of-dialog OPTIONS. The main reason to switch to topos is the line=sr-parameter. Some calls got a very long line=sr-parameter which lead to problems with different SBC vendors. line=sr-N6IAzBqLOBFsWLZfz.P7M.PszBjAWByXoSI7g.ulNJuzWqI0kqKlCxWwk.t5j6KskhrfW4u1RqtHPq31KLssWquZM.phWIp0MwpPjKpd..g-Oqs0..gSoF47.9pWotgMgLsWgqud.qfhOq46.RfP.SN7.jfWoUId.9r9NqudCEfWkFuC.RfsRU0Kg9e5Ctp0owpIWFcsmwtzkmvb> Is there any way to reduce the length of the line=sr-parameter?

Hello,
the module aimed at supporting topology hiding for calls. Is the OPTIONS part of a dialog or out-of-dialog (like a keepalive request)?
Cheers, Daniel

Hi all I have a problem with the topos module. The contact header in OPTIONS request is not changed. It is working fine with INVITE. Is there any special configuration with OPTIONS?
