Hello You can use topoh and topos module that hiding all topology. If you want to hide only contact header , uac replace is good because it has a ability restore. I assume that hiding contact header because anonymous calls. Right? Regards Yasin caner Duarte Rocha <duarterocha91(a)gmail.com> şunları yazdı (12 Şub 2019 21:56):

I think the question about the motive for altering the Contact is prerequisite to all this. It is not necessarily apt to presume that topology hiding is the goal. — Sent from mobile, with due apologies for brevity and errors.

Kamailio should not crash if it encounters a invalid header. Can you open a bug report with more information about this in our issue tracker on github? Then this crash could be just fixed.

Hello, if there is a unrelated chars in SIP trace , there may be str len mismatch for that module . Could you share header?

Hello I found TH header what is mean.It is related with Dialog module SIP headers to be added when sending local generated requests (e.g., BYE) to callee. It can be useful when you use topoh module with call-id masking (see the docs of topoh module). http://kamailio.org/docs/modules/5.2.x/modules/dialog.html modparam("dialog", "lreq_callee_headers", "TH: dlh\r\n") Yasin CANER ________________________________ From: YASIN CANER <caner_yaso(a)hotmail.com> Sent: Wednesday, February 13, 2019 12:58 PM To: Nicolas Breuer; Kamailio (SER) - Users Mailing List Subject: Re: [SR-Users] Masking Contact Header Hello, if there is a unrelated chars in SIP trace , there may be str len mismatch for that module .
