When I finish one call and immediacy make another call or press redial to call the same number, most of the time I get the engage tone, why this happen?

How many outbound PSTN channels do you have? This usually happens when you are using an analog connection to the PSTN, it takes a little bit longer to tear down the connection.

We are using the ISDN PRI (30 channels). Actually this problem happens when we redial to mobile phone, for fix line phone, we can redial and connect immediately.
Why this only happen in mobile phone?
