Hello,
Thank you for your inquiry.
FM5300 has functionality to receive and make voice calls. To enable this functionality a telephone handset with electret microphone and RJ-11 connector must be connected to “Audio” port.
Configurator part: In “Global Parameters”, “Call Settings” section there are four parameters: “Call number”, “Call trigger”, “Ringtone”, and “Auto answer”. To initiate a call an appropriate digital input has to be selected as a “Call Trigger”. To trigger the call selected input has to be connected to the ground. When the call is triggered, FM5300 dials the number which is defined in “Call Number” field. To initiate a call to FM5300 dial a number of the SIM card that is inserted in FM5300. When FM5300 has an incoming call it can play a selected tone from the “Ringtone” list. FM5300 will auto answer the call after number of rings defined in “Auto answer” field.
“Voice Settings” section includes settings for “Microphone level” to regulate microphone sensitivity and “Speaker level” to define how loud will be the speaker.
I hope this will help.
Best Regards.
