[SR-Users] inbound kamailio dispatcher faulty routing of ack after 200 OK
Gijs Kwakkel

Tue Jun 10 14:16:48 CEST 2014
client1 <> provider <> kamailio <> asterisk <> client2
when client1 calls client2, everything seems to work. sounds works.
after a few seconds the call gets terminated.
after tcpdump syslog and config checks i figured out that asterisk sends
200 OK through kamailio to the provider, after this the provider sends a
ACK to kamailio, kamailio however sends this ACK to itself and not to
asterisk.
I added the config, syslog and wireshark output (converted)
