The Regulatory Recovery Fee is a combination of fees, tariffs, access and usage charges imposed on ITS by a number of governmental entities, such as the FCC, state public utility commissions, state legislatures, county and city governments. This fee is not a tax.

The Regulatory Recovery Fee appears on your invoice under Other Surcharges. ITS believes in transparency and accountability for all of our fees. The FCC is the organization that mandates that all telecommunication companies’ invoices “contain full and non-misleading descriptions of charges.

Because a toll free number is generally available to the public, ITS is not responsible for misdialed numbers or incorrect advertising of our client’s toll free numbers by other persons or companies, and credit will not be given for these calls.

Client acknowledges and understands that 911 and E911 VoIP Services WILL NOT be available under the following circumstances:

  • The telephone device to which a particular telephone number has been assigned is moved to a location outside the premises where the telephone device was originally installed;
  • There is an outage, degradation or other disruption of power at the client’s location;
  • There is an outage, degradation or other disruption of the client’s broadband internet connection whether such connection is provided by ITS or by another provider;
  • VoIP device is being used outside the United States.
  • Under any circumstances enumerated in items 1 through 4 above, client acknowledges and agrees that it will not be liable for any inability to dial 911 using ITS’ VoIP services.
Client is responsible for informing all users of the multi-line telephone system that when calling 911 they will be responsible for providing the detailed location information of the emergency being reported. For more information about how to plan and communicate this information, please review the PBX 9-1-1 Advisory published by the California Public Utilities Commission.
ITS will charge a $30.00 fee for any returned check.
In the event that your account is 60 days past due, a disconnect notice will be sent to your billing address, and if the payment is not received within 5 days after this notice has been sent, your service will be disconnected. If you request that Service be restored after a suspension or termination due to non-payment, ITS has the sole and absolute discretion to restore such Service and may condition restoration upon satisfaction of such conditions as ITS determines, in its sole discretion, to be necessary for its protection, including requiring Client to pay a reconnection fee for each Service location being reinstated, requiring Client to execute a new Master Service Agreement, pay all past due invoices in full, pay a new installation fee, pay Early Termination Penalties, pass ITS’ credit approval and/or make advance payments. Any such monies required for restoration of such Service shall be due and paid before ITS is required to reinstate Service at the Service location.
