[otrs] how to avoid send emails

Hi guys I would like to know if OTRS could be set up to avoid send email to customer. Currently we are supporting several call shops without internet service, just using telephone lines. The user agents notifications must be kept but the notifications to customer must be cancelled. I did look for at SysConfig but I only found check MX & check mail address. If source code must to be modified, please point me where to do that. Thanks a lot.
