Plivo web SDK has no call UUID: read it from the Dial callback

TL;DR

Set a callbackUrl on your Dial XML and capture DialALegUUID and DialBLegUUID from the callback parameters. The workaround is to set a callback URL in the Dial XML and read DialALegUUID and DialBLegUUID from the callback request parameters documented under the Dial element.

Steps

1. Do not hunt the Plivo web SDK for a call UUID; it is not exposed there. Set a callbackUrl on your Dial XML and capture DialALegUUID and DialBLegUUID from the callback parameters. If your call-tracking code reads undefined off the web SDK object, this is the boundary you are hitting, not a bug in your wiring.

Source: Stack Overflow #35864808 (accepted answer): A developer could not find the call UUID anywhere in Plivo's web SDK after connecting an outgoing call. The accepted answer is blunt: the web SDK does not provide the call UUID at all. The workaround is to set a callback URL in the Dial XML and read DialALegUUID and DialBLegUUID from the callback request parameters documented under the Dial element.

Verified resolution: Do not hunt the Plivo web SDK for a call UUID; it is not exposed there. Set a callbackUrl on your Dial XML and capture DialALegUUID and DialBLegUUID from the callback parameters. If your call-tracking code reads undefined off the web SDK object, this is the boundary you are hitting, not a bug in your wiring.
