Interoperatibility between ooh323 trunk and sip trunk


i made a setup usnig a sip client, a sip trunk, a h323 trunk and my trixbox. i want to make calls between h323 trunk and sip trunk. but i have a problem like this;

i can make calls between sip client <–> sip trunk, sip client<–>ooh323 client, but i couldnt make calls between sip trunk<–>ooh323 trunk.

i have configured ooh323.conf file and created an outbound route with using custom app.

what should i do now to connect these two trunks?
