Have been playing with Zoho CRM, PhoneBridge and RingCentral for a few months and having ongoing issues.

1.  All of a sudden RingCentral will stop dialing when a call is initiated from Zoho CRM.  Shutting everything down and starting it back up will allow calls to be dialed, but after 4 or 5 calls it stops.  It goes through the motions and shows that a call is being placed, but no call is dialed.

2.  No obvious place to hang up an in-progress call from Zoho.  The window pops up when a call is placed from Zoho, but there is nothing I can find to do a manual hang up once dialing starts.

3.  Zoho CRM documentation states that calls can be recorded and saved to Zoho, yet there are no controls that I can find to do this.  *9 in the RingCentral interface will start phone recording, but what I find when dialing from Zoho is that the RingCentral interface sits there dumb and seemingly unaware that Zoho has placed a call.
