You've got another process bind to the local address. To find out which one, use lsof or netstat together with grep in order to find out which process is using the port 5060. Depending on the services file, instead of 5060 you may see sip instead of the numeric value.

#netstat -a | grep localhost
or
#netstat -a | grep 127.0.0.1
or
#lsof | grep localhost
or
#lsof # grep 127.0.0.1


After that, stop the process and restart SER.

Hope it helps,
Samuel.

I'm using openser on asteriskAtHome, I've changed the port on asterisk like 5065...but I've this problems....I've also make this:

export SIP_DOMAIN="192.168.251.12" and the others...with and without the " "

 I've warmings and 1 error....the IP are all up and works...so what could be?

0(0) ERROR: tcp_init: bind(6, 0x811b0a4, 16) on 127.0.0.1:5060 : Address already in use
