WORM has a number of dial-up telephone systems they refer to as agent systems. They are the main sources of information and interaction in OTP22.

Phone number: +1-207-813-2200

This system is used to broadcast organization-wide announcements and messages from mobile units. For more information, see AS27.

Phone number: +1-606-722-0004

This system provides access to agent codes. Its intended purpose is distribution of encrypted messages to field agents. However, it has suffered from scope creep, and serves a wide variety of other functions as well. Some of the more important agent codes are:

• 1: Telemetry as ASCII codes
• 2: Telemetry as Bell 103 data
• 3: Green terminal
• 10: Amber terminal
• 11: Red terminal
• 16000: Friendly code verifier
• 16001…16999: Agent management system
• 18000…19999: XORFS messages

Phone number: +1-412-888-0004

This system provides access to class 6 telephone numbers. These numbers appear to be out of service when called normally, but provide hidden data and messages when called through the card. To dial them, it requires the PIN of a calling card obtainable via postal mail.
