Greetings,
Is there an automated way of masking\encoding\encrypting the Contact header once it goes through a Kamailio proxy and have it restored?
I'm using uac_replace_from() and uac_replace_to() for changing these values and having them restored automatically. Is there any tool like this for Contact Header?
Cheers
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?

You cannot hide the contact with Topoh ?

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.

Hi!
Im have an endpoint device that have a problem with long routers headers. I dont know why cut the route when send packet to the server and kamailio crash because cant parse the route. If i active topoh, the router header is encrypted but is bigest than the original. If i active the topos the kamailio crashed for another reason (I need try with the lastest version).
There is another way to send routes with less info? Or other config to fix it?
Thanks!
Marcos.

Hello Marcos,
you can certainly use the textops module to remove headers, but in the case of the Route header it will probably break something regarding the SIP protocol.
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.
Best regards,
Henning
I tried and indeed the contact header is masked with topoh.
Just one question : The masquerading is done after siptrace module because the original trace is stored in database. I suppose it's the expected behavior.
I can also see that line in the trace : TH: uch Any ideas?

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

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")

Hi Henning!
When I receive a bad route, Kamailio doesn't stop working. But, the bad route generate problems with the call. The call does not hangup and the customer can't make other call because the previus call is still active.
Please, see the attached log!
Thank you! Marcos.
