1. I have a Problem in ring back tone when our customers make a call to my extensions.

2. I have a problem with some customers not all, that they cannot hear each other.

3. I have a problem that some IP phones (Linksys SPA921) can receive any call and originate calls between PBXs but cannot originate calls for mobile phones or international although at the same LAN network there is soft phone (X-lite) can originate and receive all type of calls.

I attached my ASA5510 configuration for more assistance.

thank for any helping.

This document describes how to allow the Voice over IP (VoIP) Protocols traffic on the outside interface and enable inspection for each protocol in the Cisco PIX/ASA Security Appliances.

Refer to the document for more information PIX/ASA 7.x: Enable VoIP (SIP, MGCP, H323, SCCP) Services Configuration Example

Turn off inspection for the following:

inspect h323 h225

inspect h323 ras

inspect rtsp

There's a bug in the ASA code for RTSP that I know of. Not sure if the same thing applies for H323 as well. But you didn't say what protocols your app is using. Give it a whack, let me know what happens.
