Using jq and json format to verify output

Using json allows some post verification for your call setup.

output with jq filtering

Useful filtering

gophone ... | jq 'select(.caller=="Dial" and .event=="SIP")'
gophone ... | jq 'select(.caller=="Dial" and .event=="DialogState")'

Media Testing with transcriber

CALLTRANSCRIPTION=$(LOG_FORMAT=json gophone dial -transcribe sip:49123456789@carrier.xy \
    | jq -r 'select(.caller=="Transcriber" and .text != null) | .text')

test "Please enter your PIN. Your answer is, 1234." = $CALLTRANSCRIPTION
