问题
I'm using Google Hangouts for Enterprise that comes with GSuite. When a Google Hangouts meet starts, It gives a dial-in number with a pin.
+1 xxxx-xxxx-3235 , Some PIN number (3495093#)
I'm trying to join this meeting through a Twilio voice call using the Twilio Voice API.
curl 'https://api.twilio.com/2010-04-01/Accounts/AC8bc5f1756b2e10ce344333e0ec6f7acacc46/Calls.json' -X POST \
--data-urlencode 'To=+1 xxxx-xxxx-3235' \
--data-urlencode 'From=+1xxxxxxxxxx6' \
--data-urlencode 'Url=https://demo.twilio.com/welcome/voice/' \
--data-urlencode 'SendDigits=wwwww34975093##' \
-u AC8bc5f1756b2e10c824e0ec6f7acacc46:[AuthToken]
When I execute the call through CURL I get this response message
{
"code": 21206,
"message": "Invalid sendDigits: wwwww34975093#",
"more_info": "https://www.twilio.com/docs/errors/21206",
"status": 400
}
I'm not sure what's wrong here. I'm adding half-a-second wait to the PIN using wwwww. Even passing the PIN without wwwww gives me the same error. So my question is, is it even possible to join a third party conference call through Twilio.
回答1:
There is a hidden control character:
{"code": 21206, "message": "Invalid sendDigits: wwwww34975093#\u202c#"
Remove that and it will work.
