Hi
I wonder how it comes that pj_gethostip(..) always will return the
loopback adapter in case everything else fails.
This caused a slight confusion in my trials since we established the
network connection ourselves (Windows Mobile). The connection returned
ok but I guess the IP adapter was not yet completly configured when I
initialized pjsip leading to that I got the loopback adapter configured
as my ip address.
IMO it feels like if the PJ_IP_HELPER_IGNORE_LOOPBACK_IF is set this part :
/* If else fails, returns loopback interface as the last resort */
if (status != PJ_SUCCESS) {
PJ_LOG(1,("XXX","failed to get the first one, returning loopback
if"));
if (af==PJ_AF_INET) {
addr->ipv4.sin_addr.s_addr = pj_htonl (0x7f000001);
} else {
pj_in6_addr *s6_addr;
s6_addr = (pj_in6_addr*) pj_sockaddr_get_addr(addr);
pj_bzero(s6_addr, sizeof(pj_in6_addr));
s6_addr->s6_addr[15] = 1;
}
status = PJ_SUCCESS;
}
should not be executed and an error should be returned instad of
returning the loopback adapter.
I do not really understand how the server should be able to contact me
if my Contact: header contains 127.0.0.1. However I spotted the reply a
few days ago to another question where Benny said, quote:
"
The selected IP shouldn't matter much IMO. For signaling, the IP will be
(re)learnt from REGISTER response. And for media, that exactly what ICE is
for, among other things.
"
It might very well be that I do not get the full picture here. Is there a way that the server will respond with a local IP for us in the 200 OK for REGISTER? Atleast in the current setup it does not (is ICE required for this).
