Hi, I am very happy with Topos and redis for such things. You should give it a try. And topos had some nice contact header features also. Benoit Panizzon schrieb am Do., 26.

Male sure record_route is used in kamailio script.Normally it should be used in initial invite.Le 26 janv. 2023 16:43, Benoit Panizzon a écrit :Hi Patrick Agreed, this could become an issue when we do dual stack ipv4 and ipv6 unless we use a hostname which will probably cause other issues. > But overall sip compliant component must Always follow Route ip before contact IP. I will test how the know buggy client behaves. While testing with topos I came across another issue. Then I have topos enabled on a REG instance, I see this PRACK handling: CPE <=> KAM Reg <=> KAM Core <=> IC CPE => Invite, supported: 100rel CPE <= 180 RINGING, required: 100rel CPE => PRACK => KAM Reg => PRACK to itself looping MANY times adding a VIA Header on each loop. I don't understand, why in this situation, the REG is sending PRACK to itself. As soon as I comment out topos PRACK is sent correctly to the party reqesting 100rel. Any hint where to look?

[SR-Users] Re: topos vs topoh, any reason for putting a private IP in the Contact header?
Hello,You can put any IP for Contact in topoh module private or public.The only issue is that most of the time you dont know Always what is the right IP you need to put there and is even worst if your kamailio listens on More than 2 Ips.Topoh parameter for Contact IP is a static one.so you can not change it dynamically.If your kamailio uses one IP address and you know it from start it will not change you Can put it directly in topoh parameter for Contact IP.But overall sip compliant component must Always follow Route ip before contact IP.Le 26 janv. 2023 15:27, Benoit Panizzon a écrit :Hi I'm trying to work around Route-Header and Via Issues with the two topology hiding modules topoh and topos and trying to figure out, which one works better for our environment. My conclusion so far: topos creates very clean header, but needs a database or redis. I'm always reluctant in adding more components which could fail or cause load. topoh also works, but it worries me a bit that according to the manual: https://www.kamailio.org/docs/modules/devel/modules/topoh.html#topoh.p.mask_ip a private IP is used to mask the contact header. I have come across a CPE which, as far as I see, is misbehaving by ALWAYS sending a PRACK to the Hostname or IP found in the Contact header, and ignoring Route and Via Header. So why using a private IP as 'mask' and not the IP or Hostname of the actual kamailio instance?
