Hi everybody, i'm still new to SER and i dont fully understand my config file :)
I can make outgoing calls, but incoming calls dont get routed through. They stay in a loop
at my external interface.
perhaps someone could tell where the mistake is.
Here is my config:
debug=4 # debug level (cmd line: -dddddddddd)
fork=yes
log_stderror=yes # (cmd line: -E)
listen=10.*.*.*
listen=193.*.*.*
mhomed=yes
check_via=no # (cmd. line: -v)
dns=no # (cmd. line: -r)
rev_dns=no # (cmd. line: -R)
port=5060
children=4

# know at time of request processing ? (RFC1918 contacts)

}
