Hello
Currently, an ASA firewall is installed in front of the H.323 Gateway.
After installing the firewall, calls cannot be made during a call. All firewall policies are allowed.
When talking on the phone, it is disconnected after a few seconds without ring back tone.
If you remove the ASA firewall, the call will proceed normally.
The configuration diagram was uploaded as an attachment.
Thank you

Hello,
What Mohammed describes above is a must for testing the performance of your system with the ASA, you can find an example/reference of disabling SIP inspection below:

Thank you for answer.
However, the global policy policy is set by default, but if you disable it, I wonder if there is any problem with the service.
And policy-map global_policy is h323 matched in Class-map like the attached file, so if you disable inspect h323, you think h323 communication is not correct, right?
Thank you
