Commitments and Contingencies Litigation From time to time we are subject to legal proceedings, claims and investigations relating to our business, including claims of alleged infringement of commercial, employment, intellectual property rights, and other matters. From time to time, we receive letters or other communications from third parties inviting us to obtain patent licenses that might be relevant to our business or alleging that our services infringe upon third-party patents or other intellectual property. In accordance with generally accepted accounting principles, we make a provision for a liability when it is both probable that a liability has been incurred and the amount of the loss or range of loss can be reasonably estimated. These provisions, if any, are reviewed at least quarterly and adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel, and other information and events pertaining to a particular case. Litigation is inherently unpredictable. We believe that we have valid defenses with respect to the legal matters pending against us and are vigorously defending these matters. Given the uncertainty surrounding litigation and our inability to assess the likelihood of a favorable or unfavorable outcome in such matters and our inability to reasonably estimate the amount of loss or range of loss, it is possible that the resolution of one or more of these matters could have a material adverse effect on our condensed consolidated financial position, cash flows or results of operations. Regulation Telephony services are subject to a broad spectrum of state, federal and foreign regulations. Because of the uncertainty over whether VoIP should be treated as a telecommunications or information service, we have been involved in a substantial amount of state and federal regulatory activity. Implementation and interpretation of the existing laws and regulations is ongoing and is subject to litigation by various federal and state agencies and courts. Due to the uncertainty over the regulatory classification of VoIP service, there can be no assurance that we will not be subject to new regulations or existing regulations under new interpretations, and that such change would not introduce material additional costs to our business. The Company continues to monitor federal regulations relating to net neutrality, rural call completion issues, number slamming, 911 access, access to telecommunication equipment and services by persons with disabilities, caller ID services, number portability, unwanted calls to reassigned numbers, and robocalling. As we continue to expand globally, these types of regulations are likely to be similarly enacted and enforced by the local regulatory authorities. State and Municipal Taxes In accordance with generally accepted accounting principles, we make a provision for a liability for taxes when it is both probable that a liability has been incurred and the amount of the liability or range of liability can be reasonably estimated. These provisions are reviewed at least quarterly and adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel, and other information and events pertaining to a particular case. From time to time, we have received inquiries from a number of states and local taxing agencies with respect to the remittance of sales, use, telecommunications, and excise taxes. Several jurisdictions are currently conducting tax audits of the Company's records. While the Company collects or has accrued for taxes that it believes are required to be remitted, it has reviewed its positions in those various jurisdictions as well as other regulatory fees and has established appropriate reserves. As such, we have established reserves of $7,923 and $3,175 as of September 30, 2020 and December 31, 2019, respectively, as our best estimate of the potential tax exposure for any retroactive assessment.
