Hi! I don't think it is related to dispatcher module. the following error says that something is listening port 5060 :

ERROR: <core> [core/tcp_main.c:2863]: tcp_init(): bind(d, 0x7f81495f1efc, 16) on 127.0.0.1:5060 : Address already in use

Try to execute the following command: # netstat -anp | grep 5060

It should return something like this: tcp 0 0 0.0.0.0:5060 0.0.0.0:* LISTEN 1488/asterisk udp 0 0 0.0.0.0:5060 0.0.0.0:* 1488/asterisk

Where, in this particular case, 1488 is Asterisk's PID.

If, after executing netstat, you get some results then some process is listening to the same 5060 port as your Kamailio and this is the reason why it won't start.

Hi,

Did you kill the old processes of Kamailio? "ERROR: <core> [core/tcp_main.c:2863]: tcp_init(): bind(d, 0x7f81495f1efc, 16) on 127.0.0.1:5060 : Address already in use"

Please check.
