Portrait Dialogue - SMS phone number check

Product Feature: Message/Master templates

The question has been asked if Portrait Dialogue checks for the presence of a phone number before sending an SMS.
The answer is "no", there is no built-in check for the presence of a phone number.  

It would not be a good idea to do this, since it would add an additional process before the sending of each SMS, which would have an impact on performance.  

If this is required, the best solution would be to include the "test" for a phone number as part of the Selection used for the SMS Send operation.

Alternately, this test can be added to the SMS plugin as custom code, in which case the plugin would be supported by the developer of the code, not by the Support Organization.
