ScopTEL- AdHoc Conference Feature Management

  • ScopServ is very pleased to announce the addition of a new Feature Code known as ‘AdHoc Conference’
  • The purpose of the feature is to allow users with no Admin GUI access to the ScopTEL management interface to create Conference Bridges on the fly.
  • A phone user with access to the AdHoc Conference (Admin) Feature Code by virtue of their extensions’ Class of Service can create virtually unlimited Conference Bridge applications any time one is needed by dialing some codes from their phone.
  • The Admin creator must set the ADMIN PIN code and optionally create USER PIN codes to restrict access to any of their Conference application Extension Numbers.
  • Users Dial the AdHoc Conference (User) Feature Code by virtue of their extensions’ Class of Service then dial the Conference Bridge Extension and the Admin defined PIN code to enter the bridge
  • Anyone with the Admin password of any Conference Bridge extension and a valid Class of Service applied to their extension can use the Conference PIN change Feature Code to quickly change PIN’s on an existing Conference Bridge application
  • The Conference PIN change Feature Code must be carefully safeguarded by Class of Service since it can be used to modify the USER PIN of any existing Conference Bridge application
  • AdHoc Conferences have a limited time to live set to a default of 30 days after which they are automatically deleted.

Securing Configuration Files with HTTP Authentication

  • Hackers are routinely scanning IP addresses for open ports and if they find an IP address vulnerable to brute force scanning they will execute a remote Provisioning scan using the first 6 digits of popular vendor ID’s like Polycom, Yealink and then brute force the last 6 digits of a 12 digit MAC address.
  • By example a ScopTEL server using the default HTTP listen port of 5555 can be attacked using this method. Other vendors are also vulnerable on whatever HTTP listen port they use to remotely provision IP phones.
  • TFTP is especially vulnerable on UDP port 69 because no specific path is required to the MAC.cfg file. Only the <MAC>.cfg variable is required to harvest the MAC.cfg file. TFTP should be denied on the Firewall whenever possible.
  • If you have enabled Telephony>Configuration>Security>Flood Protection and the ScopTEL Firewall and Telephony Flood Protection (Fail2ban) Service then the remote attacker’s IP address will be blacklisted by the Firewall when a brute force attack is detected.
  • But if the remote attacker knows of a valid MAC address on the network then this MAC.cfg file can easily be harvested unless HTTP Authentication is configured. The exact methodology won’t be published here as this should not be public knowledge.
  • This document will explain how to lock down a server using HTTP Authentication
