# Numeric Pager Support

Support for Numeric Pagers is comprised of a number of RTU features:

- Ability to add delays into a phone number string. Often needed to cause the RTU to pause after dialing the pager system's phone number and before issuing the follow-up digits that are to be displayed on the pager.
- Ability to add DTMF # or DTMF* into the phone number string. Often needed as a terminator character to inform the paging system that the last digit has been entered.
- Ability to add a pause for tone-detect anywhere in the phone number string. Sometimes used to detect the paging system's beep(s) heard after it answers.
- Ability to defeat voice annunciation for a specific phone number. Often just dialing the pager system and emitting a DTMF ID sequence is sufficient for that phone call. Voice reports only delay the calling of subsequent numbers.
- Ability to add DTMF A, B, C, and D tones to phone number string. These DTMF characters don't appear on standard telephones and may be used to differentiate automation equipment from humans calling the paging system.
- All voice reports are disabled for pager destinations.
- Use the "@" character as a delimiter between pager system's phone number and the Catalyst's callback number.
