Asterisk listens on ipv6 port


Please tell me why asterisk listens to ipv6 interface on random udp ports? Which module should be disabled or configured so that asterisk does not do this?

UNCONN 0      0  *    users:(("asterisk",pid=32236,fd=19))
UNCONN 0      0  *    users:(("asterisk",pid=32236,fd=21))
UNCONN 0      0               [::]:45051         [::]:*    users:(("asterisk",pid=32236,fd=20))

This might be the issue:
