Hi mates,
Everytime i do try to make my 2 xlite clients talk (which i correctly added them into the database), i encountered with the same problm, Openser perfoms authentication and return call failed 403 forbiden signal.

My setup comprise of the first box with openser 1.3 and mediaproxy the second box with Mysql and two Xlite clients in two other boxes all are in an internal network, as far as am concerned my NetAdmin have already opened ports 5060 and 3306 for me. I need your right direction on this probm.
below is my ngrep snapshot
 
mzee:/# ngrep -d eth1 -W byline port 5060
interface: eth1 (168.172.200.0/255.255.255.0)
filter: (ip or ip6) and ( port 5060 )
