Hi
Version = 5.6.0-dev0
We are seeking help to resolve an issue with registering devices to 3CX (All 3CX servers, have tried 8 different ones) . all the auth info including passwords etc are identical on the 3cx servers.
We use Kamailio to register mobile sim cards to 3rd party sip servers i.e. 3CX.
We send the normal Username, server addresses and auth details but are experiencing failures with 3CX rejecting the registration and return Proxy Auth failure 407. We have noticed in the pcaps from both sides that the expire value is changing from 180 as an example to 0.
As an example In the uac reg_dump the values are : l_uuid: +447529135850tel:+447529135850 l_username: +447529135850tel:+447529135850 l_domain: sbc-mt.asim.apalo.iohttp://sbc-mt.asim.apalo.io/;transport=udp r_username: 1001 r_domain: egte.3cx.ukhttp://egte.3cx.uk/ realm: <null string> auth_username: FdlHDC1IvA auth_password: extracted auth_ha1: none auth_proxy: sip:egte.3cx.uk:5060 expires: 60 flags: 0 diff_expires: -1738853736 timer_expires: 0 reg_init: 1738850836 reg_delay: 0 contact_addr: k01.asim.apalo.iohttp://k01.asim.apalo.io/;transport=tcp socket: <null string>

Registration looks good here The first 407 response is a password request. The second "200 OK" response is a confirmation of successful registration.
To check "expires" required PCAP.

Hello,
a general note, you should switch to a proper release and not use a “dev” version if you want to use it in production. If you are upgrading, I would recommend picking one of the maintained versions, e.g. the latest 5.8.x or 6.0.x.
Regarding the Expires: 0 – this just indicates a de-registration. The 407 is returned from the other party because it requires a proper authentication. Does the second REGISTER contain authentication information? It is accepted from the trace below.
Cheers,
Henning

Hi Henning
Thank you so much, I have inherited the platform so do not know anything about the service, I will take a snapshot of the servers and upgrade them to 6.0, seems that would at least help the situation. Re 3cx, it was operating fine until very recently, so believe the issue may actually sit within 3CX and not us, as we do send all the correct authentication info .
Kind regards
Tony
