    Default Cisco H323 Gatteway issue due to Checkpoint Firewall

    Hi All
    Can anyone help
    I am having an issue wherby we have some Cisco phones and a PSTN Gateway on Site A and the Call Manager server on Site B.
    There is a Checkpoint Firewall running R77.3 between the 2 sites.

    We are getting one way voice issues, when looking at packet captures and debugs on the gateways I can see that the Checkpoint seems to be altering the media session in the h245 messages.

    I have tried turning off h323 inspection between all the phones, gateway and call manager but its still not working

    Any ideas?
