Hello, I encountered such a problem:
An INVITE request comes to Kamailio.
Kamailio finds a location and forwards this INVITE to a device.
The device receives a push notification and registers on a new IP: port.
The tsilo module creates a new branch.
And this branch sends the INVITE.
The device responds with 100 -> 180 -> 302.
100 and 180 are forwarded to the calling subscriber, but anything greater than 300, such as 302, is not forwarded.
DEBUG: tm [t_reply.c:1363]: t_should_relay_response(): ->>>>>>>>> T_code=180, new_code=302
DEBUG: tm [t_reply.c:1448]: t_should_relay_response(): store - other branches still active
DEBUG: tm [t_reply.c:1925]: relay_reply(): reply status=3 branch=1, save=1, relay=-1 icode=0 msg status=302
Kamailio saves this code and does not pass it to the caller. Is there a way to immediately pass this 302? It seems like something can be done in t_on_branch_failure, which is invoked, but I can't figure out what needs to be done there.
Is there a parameter that can solve my problem?
A similar question has been asked before, but the link in Daniel's response leads to a non-existent ID:
