Can you try without hard coding the IP address there,

from the listen address? That will show if works properly with the
config based values.
I tried like this:
addr->sin6.sin6_scope_id =
ipv6_get_netif_scope(sock_info->address_str.s);
and it failed:
Apr 23 20:45:12 salmon /usr/bin/sip-proxy[12701]: ERROR: <core>
[core/udp_server.c:400]: udp_init(): bind(8, 0x7f88340f6fe4, 28) on
FE80:0:0:0:6E29:95FF:FE7D:37E6: Invalid argument
Then I went and tried all these:
addr->sin6.sin6_scope_id =
// ipv6_get_netif_scope(sock_info->address_str.s);
// ipv6_get_netif_scope("fe80::6e29:95ff:fe7d:37e6");
// ipv6_get_netif_scope("fe80:0:0:0:6e29:95ff:fe7d:37e6");
ipv6_get_netif_scope("fe80::6e29:95ff:fe7d:37e6");
// ipv6_get_netif_scope("FE80::6E29:95FF:FE7D:37E6");
The only version that worked is the one not commented out. So the
address needs to be exactly as shown by 'ip addr':
2: wlp1s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group
default qlen 1000
link/ether 6c:29:95:7d:37:e6 brd ff:ff:ff:ff:ff:ff
inet 192.168.43.98/24 brd 192.168.43.255 scope global wlp1s0
valid_lft forever preferred_lft forever
inet6 fe80::6e29:95ff:fe7d:37e6/64 scope link
valid_lft forever preferred_lft forever
i.e., same case and omitting of zero fields.
It would be better to use the name of the interface (in above wlp1s0)
with call if_nametoindex(ifname). Is the name available?
