You can configure the SNPP and WCTP wireless gateways for VMP.
SNPP Gateways
The SNPP protocol facilitates a link between the Internet and a TAP-compliant paging terminal. To configure VMP for use with a provider using SNPP, you must have the provider's SNPP address and port number.
Configuring WCTP Polling VMP supports polling to add additional features to AT&T Enterprise Paging, Sprint SMS, and US messaging gateways. Polling sends messages to the gateway at a set interval in order to determine if the page is sent, delivered, and read.
