H323 call failure

Hello there,
I have installed Asterisk and everything is working perfect except the h323 trunk.
To be more specific, I have installed the ooh323 plug-in successfully and when I call the remote peer everything is ok but when the remote phone is calling the local phone, local phone is ringing but when I pick up the call the remote phone is still has the ringing tone and don’t sent PTR packets.
You can find attached the configuration file oo323.conf.

Any help I really appreciated.

; Objective System's H323 Configuration example for Asterisk
; ooh323c driver configuration
; [general] section defines global parameters
; This is followed by profiles which can be of three types - user/peer/friend
; Name of the user profile should match with the h323id of the user device.
; For peer/friend profiles, host ip address must be provided as "dynamic" is
; not supported as of now.
; Syntax for specifying a H323 device in extensions.conf is
; For Registered peers/friends profiles:
;        OOH323/name where name is the name of the peer/friend profile.
; For unregistered H.323 phones:
;        OOH323/ip[:port] OR if gk is used OOH323/alias where alias can be any H323
;                          alias
; For dialing into another asterisk peer at a specific exten
;       OOH323/exten/peer OR OOH323/exten@ip
; Domain name resolution is not yet supported.
; When a H.323 user calls into asterisk, his H323ID is matched with the profile
; name and context is determined to route the call
; The channel driver will register all global aliases and aliases defined in 
; peer profiles with the gatekeeper, if one exists. So, that when someone
; outside our pbx (non-user) calls an extension, gatekeeper will route that 
; call to our asterisk box, from where it will be routed as per dial plan.
