Modifying Live Calls - Example

In order to accomplish this, you need to create a client called Alice
Start a SIP phone and register Alice
From the terminal run the following curl command
Make sure Alice is using the port 5061
The "From=" could be any number of your choice
The Url is the default sample example provided with CallAPI.

Modifying a Live Call

curl -X POST https://v1.api19.com/call/2012-04-24/Accounts/ACCOUNT_SID/Calls.json  \
   -d 'From=+16175551212' \
   -d 'To=sip:[email protected]' \
   -d 'Url=https://ACCOUNT_SID:[email protected]/callapi/demos/hello-play.xml' \
   -u 'API_Token'

You will see an output similar to the one below:
