Hi Daniel,
Many thanks - local firewall it is my bad - I thought the fact packet
sniffer can see the packet - there is no network firewall blocking the
packet - but there was an IP-Tables on the host - I shutdown the ip-tables
& now the registration is going through & I am also able to send calls
between subscribers . The log_stderror=yes is working now I can get the
error messages on the console (but for that I have to start kamailio by
typing kamailio - when I start using service kamailio start I dont get any
log messages).
Thanks its a step forward - I will review the config again for syslog
configuration as for troubleshooting its better to have the logs dumped to
a file rather then on std_error.
BTW: If you can point me to some good tutorials regarding
load-balancer(dispatcher module) it will be great -
Regards,
Faisal
