I'm having some trouble with kamailio that uses the topology hider module and
an incoming call being put onhold by the caller. The INVITE containing the sdp
a=sendonly is to the 172.19.162.1 (the topoh mask_ip) contact header from the
200 OK to the initial INVITE.
U 109.235.36.178:5060 -> 109.235.32.40:5060
INVITE sip:172.19.162.1:5060;line=pcs-
mp4KWiTsxRmtEAM3WGysx7y3xGnoxAxtuAxSuA7KEsktxGZKWgQfZD6smqlf9Gttzjy*;user=phone
SIP/2.0.
This is handled within dialog (has_totag() && !loose_route()), which in the
default config ends in a sl_send_reply("404","Not here")
Explicitly handing INVITE (just relaying), results in the INVITE being sent to
172.19.162.1 (which doesn't exist)
U 109.235.32.40:5060 -> 172.19.162.1:5060
INVITE sip:172.19.162.1:5060;line=pcs-
mp4KWiTsxRmtEAM3WGysx7y3xGnoxAxtuAxSuA7KEsktxGZKWgQfZD6smqlf9Gttzjy*;user=phone
SIP/2.0.
How to get this INVITE to the actual destination? To get the same result for
the INVITE as for the ACK to the 200 OK?
U 109.235.32.40:5060 -> 109.235.36.178:5060
SIP/2.0 200 OK.
