Altice reserves the right to increase or decrease the fee for any services offered. Fees for Optimum Voice for Business service shall be posted at http://www.optimumbusiness.com/pricing/business-phone.jsp.

Optimum Voice for Business does not support busy line verification, busy line interruption, and operator assisted calling (including person to person and station to station calling), pay services or third-party billing. Call forwarding is not available outside the continental U.S.

B. Enhanced 911 ("E-911") is a feature of the Optimum Voice for Business service that allows emergency operators to automatically know the telephone number and address of the dialing party. This E-911 feature has certain requirements in order to operate, as well as certain limitations:

i. The emergency service provider handling the E-911 call, and the address the emergency service provider will see, are linked to the address Altice has on file when the Subscriber originally signed up for service. If the Subscriber does not correctly identify where the Subscriber's voice-enabled cable modem is actually located, or if the voice-enabled cable modem is moved away from the original address, the Subscriber's 911 calls may be misdirected to the wrong address or to the wrong emergency service provider. Therefore, in order to have 911 calls routed correctly, the Subscriber acknowledges responsibility to promptly notify Altice of any change in service address.

ii. An Optimum Voice for Business Subscriber is provided with a voice-enabled modem through Subscriber's Optimum Online service (monthly modem fees may apply) that is installed at the service location and will have its own battery backup. If there is a local power outage at the Subscriber premises, the service will continue to work for as long as the battery is functional. However, if there is a disruption to the cable network or facilities, the Service will not work even if the battery is still functional. Subscriber understands that in such cases it will not be possible to place or receive calls including calls to access emergency 911 services. It is the customer's responsibility to notify Altice if the battery is not working and/or needs replacement. Altice will provide a replacement battery free of charge.

iii. IMPORTANT INFORMATION Regarding Keeping Your Optimum Voice for Business Phone Number When you Move: Please be aware that during the first 72 hours of arriving at a new service address, if Subscriber dials 911 from their Optimum Voice for Business phone, Subscriber must relay to the emergency service operator Subscriber's new (current) service address. This is necessary to ensure emergency services are dispatched to Subscriber's new service address and not the old service address in the event the emergency services operator may not have the new Registered Location in their records.

iv. If Subscriber so chooses, Subscriber may separately purchase a spare battery backup for use with their voice-enabled cable modem in the instance of a non-network related outage at http://shop.surfboard.com/cablevision-store/.

C. Optimum Voice for Business International Calling. Optimum Voice offers an International Calling Service for direct-dialed calls made from the Subscriber's business or from any phone via the Optimum Voice International Calling remote access number to destinations outside of the United States ("U.S."), Puerto Rico, Canada, and the U.S. Virgin Islands at per minute rates. The Optimum Voice International Calling Service is automatically enabled for each line, including, where applicable, the SIP Trunk Pilot telephone number. To activate the International Calling Service, Subscriber must login to the Optimum Business Account Center and activate the service on the desired line(s). Audio-text lines/destinations are excluded from Optimum Voice International Calling.

IMPORTANT: It is the customer's responsibility to properly secure their own phone system and network, including but not limited to securing the private branch exchange ("PBX") to prevent the PBX from being compromised and fraudulent calls from being made. If fraudulent calls are detected, Altice reserves the right to disable International Calling without prior notice until the customer properly secures their phone system (including the PBX) or network. Customers are responsible for all charges incurred as a result of an unsecured phone system or network.

i. Monthly International Plan Charge. Subscriber will be charged a monthly international plan charge upon activating International Calling. The monthly international plan charge covers all lines on the account and is charged to the account even when no international calls are made.

ii. Per Minute Rates.The per minute rates vary by destination and are posted at: https://business.optimum.net/international/popRatesNew. The per minute rates are subject to change at any time and any updates will be effective upon posting at: https://business.optimum.net/international/popRatesNew. Charges for Optimum Voice International Calling at the per minute rates will appear on Subscriber's monthly billing statement for the relevant usage cycle (the "Usage Cycle"). Optimum Voice International Calling will be billed in sixty (60) second increments and rounded up to the nearest sixty (60) second increment.

iii. Calling Limits.

a. Altice reserves the right to impose limits on the unpaid balance for Optimum Voice International Calling charges incurred by Subscriber during a Usage Cycle (the "Calling Limit"). Altice shall have the right to modify Calling Limits, either on an individual Subscriber basis or as applied to all Subscribers, in its sole discretion and impose varying Calling Limits depending on Subscriber's account status.

1. Subscribers in good standing with OV Service for less than ninety (90) consecutive days have a Calling Limit of One Hundred and Seventy-Five Dollars ($175) per Usage Cycle; and

2. Subscriber in good standing with OV Service for ninety (90) or more consecutive days have a Calling Limit of Three Hundred and Fifty Dollars ($350) per Usage Cycle.

b. Subscriber may create a "Calling Limit" whereby Subscriber sets a maximum aggregate amount of fees for Optimum Voice International Calling that can be accrued during a Usage Cycle which amount is lower than the Calling Limit imposed by Altice. Except as described below, Subscribers will not be able to complete Optimum Voice International Calling calls in the event they have reached the Altice-imposed Calling Limit or the Subscriber-designated Calling Limit.

iv. Remote Access Feature. Subscribers can use the remote access feature with Optimum Voice International Calling at per minutes rates while away from Subscriber's place of business.

D. Subscribers of the Prepaid International Calling Plan may find more information at: https://www.optimum.net/pages/OV/Prepaid-Business.html.

E. Optimum Voice for Business offers professional installation of a voice-enabled modem. Optimum Voice for Business provides a business wiring solution that enables customers to use Optimum Voice for Business as standard telephone lines. Altice will use a network interface device (NID), a common connectivity panel used in commercial locations and the NID will be the demarcation point for the Optimum Voice for Business service. Altice will connect the wiring from the cable modem to the NID. An existing cable modem for Optimum Online might not be located near the NID on the Subscriber premise. Altice will determine the best method of installation and location of the modem to deliver the service at the time of installation.

Altice will be responsible for delivering dial tone to the demarcation point (NID) only. Subscriber will be responsible for wiring from the NID out to the individual phone(s). Altice reserves the right to determine the manner in which the business wiring solution is executed. In certain cases, Altice may be required to alter or adapt the Subscriber's inside wiring so that Optimum Voice for Business is available on the existing phones. Optimum Voice for Business does not offer a wire maintenance plan. The Subscriber is solely responsible for maintaining all inside wire and phones within the business. Optimum Voice for Business will troubleshoot and fix reported problems for a specified service charge. The service charge is based on the then current rate in effect. In certain buildings such as multiple dwelling units, Optimum Voice for Business may not have access to the Subscriber's inside wiring located within the business. In these instances, Altice has the right to determine how best to wire the Subscriber's business.

F. Alarm Systems. If Subscriber has a centrally monitored system, which is not (i) a high security monitoring system (UL 681 or similar) or (ii) an emergency medical alert system, Optimum Voice for Business will be wired so that it may be available for use with such system. This request must be made at the time of sale. If you have a high security monitoring system (UL 681 or similar) or an emergency medical alert system, you must use an alternative connection. Although Optimum Voice for Business will supply a connection that will allow the operation of Subscriber's existing business security system, Optimum Voice for Business does not guarantee that any such system will be in complete operational order following the installation of Optimum Voice for Business. As such, it is Subscriber's obligation to contact their security system provider to inform them of your Optimum Voice for Business installation and any change in phone number and to request a complete operational test of such system immediately following installation of Optimum Voice for Business service. In addition, it is your responsibility to test your system on a regular basis. Optimum Voice for Business installation will insure proper wiring from the cable modem to the Altice demark (NID/wiring block). However, any inside wiring from the NID/wiring block to the alarm panel is Subscriber's responsibility. In the event of a large-scale power outage or network outage (whether unplanned or maintenance related), Optimum Voice for Business service, including any security system, which uses Optimum Voice for Business to connect to central station monitoring, will not function.

Altice does not support the use of Optimum Voice for Business as a connection between medical alert systems or, (ii) any high security monitoring systems (UL 681 or similar) and the central station monitoring and Subscriber must maintain an alternate connection. Altice does not support the use of Optimum Voice for Business as a connection between fire alarm systems (UL 864 or similar) and the central station monitoring for service locations in Pennsylvania. If Optimum Voice for Business is used as a connection between fire alarm systems (UL 864 or similar) and the central station monitoring for a Subscriber service location as permitted hereunder, Subscriber agrees that it will be solely responsible for contacting its authorized central station monitored fire alarm system provider to test and verify that the central station monitored fire alarm system is in good working order following Altice's Service installation, including the testing of proper line seizure functionality and the successful transmission of signals at the supervising station.

G. Anonymous Calling. Optimum Voice for Business provides the option to hide caller ID information on a per call basis via *67 or for all calls through My Optimum Voice web portal. However, if Subscriber is calling an Optimum Voice Toll Free number, caller ID information (Name and Telephone Number) will be displayed to the owner of the toll-free number regardless if the feature is active or not.

H. Caller Name. Optimum Voice for Business will associate the Subscriber's business name with the Subscriber's telephone numbers on the account to be displayed in association with Caller Name (CNAM) lookup services provided by Optimum Voice and other telecommunications service providers for all calls made from any of the numbers on the account. Following initial service commencement, Subscriber can modify and manage the Caller Name(s) for each telephone number on the account through the Optimum Business Account Center located at: business.optimum.net. Subscriber agrees to the following: Caller Name submissions(s) shall not mislead or impersonate any person or company; Caller Name submission(s) shall not contain false information and shall accurately represent the name of the company that subscribes to the service; Caller Name submission(s) shall not contain abusive, defamatory, vulgar, obscene, racist or any other language objectionable to any person or entity as determined by Altice or the publisher in its sole discretion; and Caller Name submission(s) shall comply with all relevant laws, rules and regulations.
