I don't see us generating that uuid anywhere.

However in the official node library for ari (which we use). It does use node-uuid which generates a uuid:

>
> Asterisk crashed in the middle of our dangerous demo. We setup a system that would get an SMS then make an outbound call and bridge that call in. At around 43 calls Asterisk was at about 177% cpu. Since we lost the Dangerous Demo because of an Asterisk crash we'd like this moved to our L4 support for immediate fixing. Then please bring back everyone for Astricon's Dangerous Demos so that we can try this again and win, of course.

> Thanks for all you do and thank for Astricon and Asterisk!
