In Verto JS is there a way to detect if/when the following methods succeed or fail:

call.dtmf()

verto.newCall()

For verto.newCall() for example, if it cannot connect through the websocket, it gets stuck in the requesting state.  If there is no other way, I can do my own timeout and check the state then.  Not ideal but if it's the recommended way, it can be done.

However for call.dtmf() there does not seem any way to know whether it actually reached the FS or failed in some way.
