sim300 + incoming call number
When using SIM300 to transmite GPRS data, what happens when there is an incoming call (somebody dials the sim card phone number) while the GPRS connection is still open ? Is there a way to block incoming calls using the module ??

gprs incoming calls
When the module receives an incoming call it sends an unsolicited result code "RING". If a GPRS connection is open when a call comes in the GPRS connection is suspended until the call is terminated, at which time it will resume. A call can be terminated by answering using "ATA" commadn and then hanging up using "ATH" command. Or wait until caller terminates call.

sim300 incoming call

Thanks for the response.

So, does the suspended GPRS connection get resumed automatically once a call is terminated using the "ATH" command ?
