In client_test.go, if you would like to run tests just update these variables correctly.
var (
var (
testTelapiSid = "your telapi sid"
testTelapiAuthToken = "your telapi auth"
testNumberTo = "Destination number of a text"
testNumberFrom = "Where the text should send from" //Correlates to telapi sid being used
testCallSid = "A random call sid for the call tests" //Also correlates to telapi sid being used
testRecordingSid = "A random recording sid on the account"
)
Then run go test.
