问题
I need to make outgoing calls from browser and i set capability token with the master account.
Then i make a call request to twilio from browser and return a twiml from my server.
In the twiml, i set the callerId to a subaccount validated outgoing phone number.
When dial to another client, it works fine. But, if dial to a phone number it not work.
From the debugger i saw this error:
it said callerId must be provided for TwilioClient and SIP calls when using Dial.
I dont know why, I need a help.
