The Orchid Telecom GSM200 Mobile Gateway hugely simplifies the issue of how to take calls in an area with no landlines. Simply connect the unit to a hybrid channel on your mixer and put a normal mobile phone simcard into it and you can take calls on the air! It converts a mobile phone signal into a landline signal, so it will connect directly with the hybrid channels on the D & R Airmate USB or into any other telephone hybrid.
The Orchid Telecom GSM200 Mobile Gateway makes receiving phone calls live on air in areas with no landlines that much simpler. It is one of the most cost effective ways to receive a call on air using a sim card, short of patching your mobile phone directly into the mixer, which may lead to poor sound quality.
