### Description Kamailio (5.8.x): SIP proxy FreeSWITCH: Media

ref: https://kb.asipto.com/kamailio:kamailio-mixed-ipv4-ipv6 https://lists.kamailio.org/pipermail/sr-users/2018-April/101159.html

OS: Debian 12 gateway: aaaa:bbb:cccc:20::1 ipv6: aaaa:bbb:cccc:20::41e

kamailio.cfg: ``` #!define ADDR_IPV4 xxx.xxx.xxx.xxx #!define ADDR_IPV6 [aaaa:bbb:cccc:20::41e]

listen=ADDR_IPV4 listen=ADDR_IPV6 ```

I execute ```netstat -nlutp``` ``` tcp6 0 0 aaaa:bbb:cccc:20:::5060 :::* LISTEN 1691274/kamailio tcp6 0 0 aaaa:bbb:cccc:20:::5061 :::* LISTEN 1691274/kamailio udp6 0 0 aaaa:bbb:cccc:20:::5060 :::* 1691222/kamailio ```

Why I set listen ip is ```aaaa:bbb:cccc:20::41e``` but kamailio stripped the last part of the address ```aaaa:bbb:cccc:20::```

Thank you.
