Refresh when expiration timer run out

[E3V3A]

Problem:
Module stops responding after a period of time when not used.

Possible causes:

• API access token expires
• socket connections are cut/removed after some (unknown?) time when not used?

Both (most?) voice APIs are dependent on an access token that is used to access the voice services. This access tokens has an expiration timer associated with them. When they run out, you need to refresh it with the refresh tokens.

These timers run out: (need check):

• Amazon: 3600 sec
• Google: 3600 sec ?
