SIP Trunks and SIP Endpoints, are devices or software interfaces that accept SIP calls from the ACD network.

In some instances, ACD is responsible for the SIP endpoint, where the SIP endpoint is an ACD controlled device, ACD is responsible for ensureing the SIP enpoint is secure.

Where the SIP endpoint is not controlled or directly managed by ACD:

  • ACD is not responsible for performing security functions on endpoint devices.
  • ACD is not responsible for mis-configured or poor security on the account associated with the end-point device. ACD enters a password security that is requested by the end-user.
  • Securing equipment that is not under the direct control and ownership of ACD.
  • Any Expenses or fees associated with calls to and from ACD SIP Trunk accounts.
  • Any fees or expenses to consultants, other service providers for securing non-ACD owned and controlled equipment.
  • The customer is responsible for paying any fees and expenses associated with calls originating from your accounts.
  • ACD is not responsible for any call blocking functions.

Bottom line: the end-user accepts full responsibilty for any mis-configured equipment or accounts when they are in control of the end-point device.

ACD recommendations for security on endpoint devices

  • Always use a complex password.
  • Change the password occassionally.
  • Encrypt the passwords.
  • Ensure that there is adequate firewalling
  • Ensure keepalives are used to a static IP address.
  • Configure the endpoint to a static IP Address and relay that address to ACD.
  • Review your call logs on
  • Block unneccessary services in, such as international long distance, etc.
