This demo starts a softphone instance and waiting for inbound calls.
Whenever there is an inbound call, the demo will auto answer the call and does the following two things:
- repeatly play "test.wav" to to caller, never stop
- if the caller press "*", the call will be transferred to another predefined number.
yarn install
In order to run it, you will need to create a .env file with the following content:
SIP_INFO_OUTBOUND_PROXY=sip10.ringcentral.com:5096
SIP_INFO_DOMAIN=sip.ringcentral.com
SIP_INFO_USERNAME=
SIP_INFO_PASSWORD=
SIP_INFO_AUTHORIZATION_ID=
ANOTHER_CALLEE_FOR_TESTING=
ANOTHER_CALLEE_FOR_TESTING is the number to transfer to when caller presses "*".
yarn test
Make a call to the softphone instance. Normally, you should be able to reach it by dialing SIP_INFO_USERNAME.
Listen to the audio and confirm that you can hear something. Confirm that what your heard is repeated endlessly.
Press "*" and confirm that the call is transferred.
The audio to be sent to the caller must be playable by command:
play -t raw -b 16 -r 16000 -e signed-integer test.wav
For more information, please refer to audio formats.
The 8th audio streaming becomes silent.
