System Information


The application uses CDYNE for sending text and voice alerting messages. Sending SMS Text messages via a 3rd party aggregator is the most efficient and reliable method for sending messages.

Alerting Carriers

Not all carriers are sent via CDYNE. Users with pagers and cell subscriptions with smaller companies must be sent via SMTP/email. Messages sent via SMTP are vulnerable to the same delivery issues as regular emails i.e. spam filters, and getting lost. Furthermore, carriers that allow SMTP messages are often changing the criteria to send messages.
