You can set up a number through Twilio to be able to receive phone calls and text messages to your Twilio number that route to a cell phone or office line. You decide how calls and texts route, and can set different rules for different days/times.
You can also place outbound calls or send text messages to patients from the EMR using your Twilio number. When you select to place a call from the EMR using Twilio, Twilio will first call you (at the number you specify), then connect to the patient's phone number. The patient will see your Twilio number in their caller ID.
Currently, calls to/from your Twilio number are logged, but that log is not shown in the patient's chart in the EMR. Text messages sent to your Twilio number, or sent out from the EMR are logged and shown in the patient's chart.
