It would be very handy to have workflow triggers for first-time callers and phone calls of a certain duration.
Use Cases:
When a call comes in, we have a workflow to create an opportunity. For certain types of businesses we need to allow duplicate opportunities. Because we have no simple way to filter out repeat callers, we end up with duplicate opportunities for the same potential sale. If we had a trigger for first-time callers, we could avoid duplicate opportunities.
Piggy backing off of the above, it would be great if we had a trigger for phone call duration. We don't want to create opportunities for phone calls that are under a specific duration, such as 30 seconds for example. I know a work around for this may be to use call connect with a call connect status, but in some cases we can't use call connect.
