master ignores OPTIONS messages via IPv6 socket

[sergey-safarov]

Description

Added IPv6 listeners into the default config file.

listen=udp:[2600:1f18:63e1:6936::300]:5060
listen=tcp:[2600:1f18:63e1:6936::300]:5060

Kamailio is able receive REGISTER messages. But ignores OPTIONS. When #!define WITH_DEBUG kamailio shows nothing on OPTIONS messages.

Troubleshooting

Reproduction

1. add IPv6 listeners into default config
2. send OPTIONS messages to kamailio.

when kamailio started with

kamailio -DD -E -dddd

Then I can see in the output only this

 2(1410) DEBUG: <core> [core/udp_server.c:516]: udp_rcv_loop(): probing packet received from 2600:70FF:B0CF:0:8099:5CFF:B271:D303 37819

my mistake
kamailio bound to 5060, but options send to 5080.
