[SR-Users] Kamailo - Problems with RTP streaming.

the log errors don't seem related to rtp proxying.

Can you paste here what you have in kamailio.cfg at line 943?

The other error in syslog is related to a duplicate key, most probably 
in cdrs table or some other table you populate with sql_query() from 
kamailio.cfg -- the conflict is on unique key 'uk_cft'.

In both traces, labeled working or not working, there is no rtpproxy 
invoked for signaling, thus no rtp relaying done by sip server. The rtp 
stream should go directly from caller to callee. The ip addresses 
suggest that caller and callee are both in the same local network as sip 
server. So, unless there are some firewalls around, all should just go 
fine. Or maybe there are some bugs in the softphone. Kamailio is not 
involved in rtp at all.
