*Nextlink Voice requires a Nextlink Internet connection. 911 service operates based on registered address and Nextlink will confirm 911 access prior to notification of number porting. All of your long-distance calling is included for calls made to the contiguous USA and Canada. Fire alarms, security alarms, postage machines, ATMs, point of sale systems (POS), fax, and other systems may not be compatible with VoIP. We will inform you of this and more once we complete an on-site discovery. Packages offered do not include taxes and fees. Number porting could take up to 45 days but 14 – 21 days is typical. If a power outage occurs, you will not be able to make or receive calls, including 911 calls, unless you have battery backup power for the subscriber module and POE for internet connectivity. During a power outage, if you wish to conserve battery power for making and receiving necessary calls, such as emergency or 911 calls, you should avoid making unnecessary calls and not use Nextlink Internet services during the outage. 8-hour holdover uninterruptable power supply (UPS) can be installed at the time of new service installation or a service call if dispatched after initial installation. A 24-hour UPS is available for purchase can be installed at the time of new service installation or at a service call if dispatched after initial installation. These battery backup systems can be purchased on your own directly from stores, Amazon, or directly from UPS manufacturers.

You may call other phones in your PBX with an extension, even if they are in other locations.

You can redial the last number you called.

All PBX Include the Following Features

Auto Attendant
An automated recording that answers the phone and provides a personalized message to callers with options for connecting to the operator, dialing by name or extension, or connecting to up to nine configurable extensions. Configuration via the Customer Portal allows for hours of operation to be modified, with different options available for hours that the company is open or closed.

Company Main Number
Phone number with unlimited incoming minutes that can be configured to point to any group extension in the PBX (such as an auto attendant or hunt group).

Corporate Directory
System Users are networked for extension to extension calling.

Hunt Groups
Allows users within a group to be included in a specified sub-group to handle incoming calls received by an assigned Hunt Group’s phone number. Within the Customer Portal, company administrators can choose from “hunt” schemes, each of which rings the specified phones in a different manner.

Music on Hold
Enables company administrators to upload an audio file (.wav file containing music, advertising, etc.) onto the system to be broadcast to parties while on hold.

Add-On Features

Call Recording
Allows a user to record their calls in either an always on or on-demand mode. These recording capabilities can allow for personal monitoring or supervised monitoring of recorded calls.

Toll-Free Numbers
An “800” number with inbound calling charged a toll to you, not the caller.

Secure Communications

All of your customer and corporate data is guarded against security and compliance breaches, putting your client’s concerns at ease during times of ID theft and other malicious threats.

Your institution requires the highest standards of security and reliability, so Nextlink offers enterprise-class reliability so you can be sure that key personnel can be reached immediately. With Disaster Recovery and Business Continuity Safeguards in place at four data centers geolocated for five 9’s reliability and backup, your phone systems will never go down, even in natural disasters.

Transport Layer Security (TLS) is a standard SIP request/response which has been encrypted. This operates in the exact same manner as the more traditional HTTPS. As SIP is only used for establishment, control, and teardown of calls, SIP over TLS does not encrypt the actual RTP voice traffic.

SRTP is the Secure Real-Time Transport Protocol; it encrypts the voice traffic. This differs from TLS as it uses opportunistic encryption to exchange keys. Since SIP over TLS already has negotiated a secure channel prior to any traffic being passed, SRTP exchanges its cipher key in the SDP of the encrypted SIP Message.
