Hello, I do have 2 network interfaces in 2 different networks, so I don't know if disabling this warning will be the best option here, it's just like a workaround. The weird thing is that the 'rr' Kamailio is complaining ( sbc-fqdn:5067) is actually the IP address (socket) he is listening on: ping sbc-fqdn 64 bytes from kamailio (1.1.1.1): icmp_seq=1 ttl=64 time=0.041 ms kamcmd corex.list_sockets { PROTO: tls NAME: 1.1.1.1 ADDRLIST: { ADDR: 1.1.1.1 } PORT: 5067 MCAST: no MHOMED: no SOCKNAME: - ADVERTISE: - } (IP Address is replaced) I was trying to enable sockname_mode for the rr module ( modparam("rr", "sockname_mode", 1) ), but didn't notice any changes in the RR header.

Hello, there is a rr modparam to turn of that warning, if you do not have many network interfaces/sockets that would require to select a specific one, then should be enough.

Perfect, adding advertise domain name to the listen parameter fixed the issue. Thank you On Thu, 25 Feb 2021 at 12:01, Daniel-Constantin Mierla <miconda(a)gmail.com> wrote:

Hello, sockets are matched only on address/ip or advertised value, if you want to match on domain, you have to add advertised address to listen global parameter. There is no dns done on route header to do the match, that can have significant on performance, security and routing impact (e.g., a bad actor controlling whatever dns record can point a domain to your sip server address and then your server believes that route headers are added by itself). You can eventually do it yourself in the config using ipops module and select the socket based on the result.
