    Arrow GSM Modem ATH command

    When you send ATH to the modem while an incomming calling is waiting (RING) to be answered, it sends the number to the receved call phone book. Does anyone know if the network will charge you a call if you do this.

    It depends on your telecom company and the country you live in. In some countries, you will be charged for this but in other you won't, because a phone call's duration must reach a certain time duration (say 7 seconds, sometimes less) for incurring a charge.

    Do you know what the correct AT command is to reject a call. What I want to do is when the modem RING, reject the call so that it goes to the missed calls phone book.

    ATH command

    When you send the ATH command while there is a waiting call, it puts the call in the "RC" (received call) phone book and not in the "MC" (Missed call) phone book.

    I suspect that that happens because the ATH command is treated as a flash command when you have a call waiting. However, the details regarding billing depend on the telecomm provider. In most coutries, you will not be charged for it, even if the call is registered under the RC category. The simplest way to solve this query is by requesting a detailed statement from the telecomm company and see whether calls in this category incur any charges.
