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?
 
Thanks!
 
Best Regards
Enzo

Betreff: Re: [SR-Users] Use topos module to hide contact in OPTIONS request

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?

modparam("topos_redis", "serverid", "srv8")
modparam("topos", "branch_expire", 14400)
modparam("topos", "dialog_expire", 14400)
