Yes you can!
Until now, you/your co-workers would have received email alerts for missed-calls (calls which reached your co-workers phones) but there would have been no email notification for a call-attempt (when the caller cuts the call even before we connect the call to your co-worker).
This FAQ explains illustratively what call-attempts and missed-calls mean.
From now on, you can get email notifications for call-attempts as well
Here's what you need to do:
1) Enable the 'call attempt notification email' field in https://my.exotel.com/notifications
Once you have set this up you will start receiving email notfications for call-attempts on any Exophone in your Exotel account. Here's a sample email:
Call Attempt from <caller-name> (<caller-number>) on <app-name>
The number 04067193355 (Connect Cust to Acc Mgr - v2) received a call from Karthik (09884193060) at Wed, 05 Feb 2014 15:13:17
To assign this call:
I want to receive call attempt notifications only for certain Exophones or Apps. How can I do it?
Right now we don't have a way to send notifications only for selcted Exophones. But, you can setup an email filter in your account and filter for an app name (in the subject) or for the Exophone (in the body).
If you are using Gmail and need help in setting up the filters, this article will be helpful.
