[SR-Users] TOPOS (5.5) answers '404 Not Here' when b side send BYE

[张 阳]

Dear Daniel:
When I was using the topos module, I found that if a bye message was sent from side B, kamailio would return a 404 message. When I remove the topos module, the call is normal, attached is sip pcap.
172.18.67.50:5060 and 172.18.67.40:55066  Are different ports monitored by the same kamailio
Looking forward to your reply!



My cfg is too long,I will key information for cfg:

modparam("ndb_redis", "server", "name=srv8;addr=127.0.0.1;port=6381;db=2")
modparam("topos", "storage", "redis")
modparam("topos", "db_url", "redis://127.0.0.1:6381/2")
modparam("topos_redis", "serverid", "srv8")
modparam("topos", "rr_update", 1)
