What are Voice Codecs?

June 13, 2017 by Ying-Hui Chen

voice-codecsCodecs stands for Coder-Decoder. It is an audio signal converter that compresses your voice into digital form in order to transport it over data networks. Compression is needed to minimize the bandwidth that’s used to transport the voice. Large volumes of calls that connect fit into the largest bandwidth pipes will need to be compressed.

There are many vocoders, differing by the amount of bandwidth they consume, the voice quality they produce, their resiliency to network impairments and license model (free or royalties based) for using them. See a list of the most common VoIP Codecs.

An SBC may receive one vocoder on one side of the call and need to convert it to another vocoder on the other side of the call. This conversion is called transcoding. A common example would be an enterprise with an IP-PBX system supporting G.711 (a coder type), where the service provider SIP trunk supports G.729.

How Does a Session Border Controller (SBC) Work?

June 9, 2017 by Ying-Hui Chen

how-does-a-sbc-work
A Session Border Controller (SBC) is a powerful back-to-back user agent device that sits at a point of demarcation for SMB and Enterprise businesses to provide services such as call control, security, interoperability and voice optimization. Let’s take a closer look at how a Session Border Controller works to optimize your VoIP performance!

Generally, the main duties of an SBC can be separated into four sections: Topology Hiding, IP Addresses Translation, Encryption and Transcoding, and Classification.

Topology Hiding

An SBC locates in the middle of the call path between a service provider and an IP-PBX. When a call is generated and arrives at an SBC from the PBX, the SBC filters out any sensitive information, so no outside intruders can exploit this information for hacking the enterprise VoIP network. This is called Topology Hiding.

IP Addresses Translation

An SBC also translates local IP addresses of the callers to the WAN IP address of the SBC and performs protocol normalization, a process that an SBC manipulates the call message to adhere to the service provider’s protocol implementation including possible number manipulation.

how-does-sbc-workEncryption and Transcoding

Some SBCs also encrypt calls and perform transcoding when necessary. If an enterprise is connected to multiple branches and service providers, an SBC will decide where to route the calls to. It makes routing decisions based on multiple criteria: reachability, call cost optimization and path with the best quality.

Classification

So far, we have only talked about the outgoing calls. What about the incoming calls? It basically follows the same steps as for outgoing calls but with one extra layer of examination which is called classification, a process of careful inspection on the incoming calls to identify intruders and hackers.

How to Pair Your Cell Phone to the Plantronics Savi w740

June 8, 2017 by Steve Lopian

If you have a desk phone, then chances are you have a headset. I can’t even imagine someone who still uses their handset at work. It is a thing of the past, and honestly, maybe we should get rid of the handset all together.

Okay, maybe that is going a little too far, but having a headset for your desk is something everyone should (and most likely does) have. It is something that is relatively inexpensive and can make your day flow much easier.

There are all types of headsets out there.  Some people are fine with having a basic wired headset, while other people can’t live without the freedom of going wireless.  The preference comes down a matter of how often you get up and leave your desk, but the differences don’t stop there.

There are even more options available when choosing a headset for your desk at work.  One of the most popular features a headset can have these days is Bluetooth.  Having Bluetooth on your headset allows you to pair devices other than your deskphone.  Other devices like your personal smartphone!

This is an important feature for someone who is in, let’s say, sales and chooses to give out their cell number to clients in order to make themselves more accessible. Perhaps this is something that you might be interested in doing if you have not already done so.

With that in mind, let’s go over how to pair your cell phone to your wireless, Bluetooth headset on your desk.  As an example, we will use the Plantronics Savi w740.plantronics-headset

How to Pair Your Cell Phone to the Plantronics Savi w740

  1. Press down and hold the Bluetooth pairing button for 4 seconds on the Savi base.  A LED indicator will flash red and blue once it is active.  It will remain this way for up to 10 minutes.
  2. Make sure Bluetooth is turned on, on your smartphone and go into Bluetooth search mode.  Select SAVI 7xx from the list of found devices.
  3. If prompted by your smartphone, type 0000 as a passcode.  The LED indicator will turn solid blue on the Savi base when it has an active connection with your smartphone.
  4. While wearing your headset, short press base mobile button on the Savi base.
  5. Dial a test call from your smartphone.
  6. End the call by pressing the call control button on your headset.

And it is as simple as that! If you are familiar with using Bluetooth, then this should be extremely similar to other devices you have paired in the past.  Once you are paired, you just might find that you have become the coolest guy or gal in the office!

Do you have a Plantronics Savi w740 on your desk? If not, does your headset have Bluetooth? What kind of headset is it? We want to know!

c-fakepath-netvanta-3140-1

Top 5 Benefits of The NetVanta 3140

#1 Flexibility and Redundancy

The NetVanta 3140 is ideal for multiple applications where Ethernet redundancy is needed given the three Gigabit ports that can be either LAN or WAN facing. This solution also features a USB interface that can be used for 3G/4G backup. If your deployment still separates voice and data network, the NetVanta 3140 will be a perfect fit with a single WAN link and the other two Gigabit interfaces.

#2 Feature-rich ADTRAN® Operating System (AOS)

The ADTRAN Operating System (AOS) allows for the support of static and default routes, demand and policy based routing, and provides fast, accurate network convergence using routing protocols such as BGP, OSPF, RIP, and PIM Sparse Mode for multicast routing.

The AOS provides a powerful inspection firewall that can protect against common Denial of Service (DoS) attacks like TCP syn flooding, IP spoofing, and more. Its Web-based GUI comes with step-by-step configuration wizard, management capability, and the ability to upload firmware updates.

#3 Enterprise Session Border Controller (eSBC)

As having an eSBC became mandatory for most VoIP deployments, the NetVanta 3140 also includes an optional eSBC to secure and troubleshoot your SIP to SIP communications. This featured eSBC builds strong, robust network security and enables voice interoperability, delivering a truly converged application platform at the customer premises.

#4 Voice Quality Control

The NetVanta 3140 uses Low Latency Queuing, Weighted Fair Queuing (WFQ), Class-based WFQ, and DiffServ marking to prioritize mission-critical traffic and control network congestion. It also deploys Voice Quality Monitoring (VQM) to capture, MOS, jitter, delay, and packet loss statistics to troubleshoot VoIP calls over the WAN. This diagnostic tool is extremely valuable because it isolates the network issues in real-time and ensures superior call quality at all times.

#5 VoIP Ready

The NetVanta 3140 highlights a specialized SIP ALG that allows SIP traffic to traverse NAT-enabled firewalls. This interoperability allows IP PBXs, phones, and other SIP-based devices to set up, tear down, and pass voice and call control messages seamlessly through the integral NAT-enabled firewall.

How VoIP Transforms Small Hotel Businesses into Big Players

June 2, 2017 by Ying-Hui Chen

voip-for-hotels

The hospitality industry is extremely competitive when it comes to pricing and services. Especially when customers can get all the information with just a few swipes or clicks on their smartphones and compare you and your competitors side-by-side within minutes.

That being said, how to stand out within that space has become a big topic. You might also be thinking that there’s no way you can achieve this without it costing your business a pretty penny……or is there? What if I told you there’s a way to be more competitive and save more? Let’s check out how VoIP not just reduces your costs but also generates more revenue for your hotel business!

Reduce Costs

Reduce Expansion Costs – VoIP networks reach anywhere with an Internet connection, therefore, when a hotel needs to add a new unit such as a fitness center or a dining area, no extra installation or cabling will be needed. You will also save a lot of trouble and money without closing the location or disturbing your guests for additional installation or maintenance.

Cut Infrastructure Costs – traditional hotels require separate networks to process telephones and data which involves extra costs of installing, wiring as well as the costs of management and maintenance. VoIP uses an existing data network, therefore, eliminating the need for separate networks and too much wiring. Besides, your VoIP service provider will be responsible for maintaining the infrastructure in the cloud, so you can save on the maintenance costs and the cost of hiring IT staff!

Lower Off-site Communication Costs – VoIP Service collects everything under one roof even when you are on the road. Because VoIP call rates are usually fixed regardless of the distance, you will be able to save costs on traveling and long-distance call rates and easily manage group communications from a single source.

Increase Revenue

Guest Phones – By providing your guest more paid communication services, your hotel can open up more business opportunities and generate additional revenue. For instance, VoIP allows you to offer your guests voicemail services, instant messaging, outbound calling, etc.

Customer Satisfaction – In the long run, VoIP service will improve your customer satisfaction and indirectly boost your overall revenue. Ex: Lower customer wait-time by using customized call routing on an inbound number and caller ID.

By integrating your VoIP system with your CRM system, you can also get access to guest information right from the same system, speeding up check-in/out process time and also process special requests such as taxi pickup notification and wake-up calls with more efficiencies. In this way, you can improve convenience and increase customer loyalty.

Effective CommunicationVoIP service comes with a lot of useful features such as Find Me/ Follow Me, Call Parking, IM, and advanced analytics which enables effective and efficient staff communications and management. Through the bring your own device (BYOD) solution, your staff can use their smartphones, laptops, or other devices when making calls or sending messages. With VoIP call features, your hotel will be more responsive to customer inquiries and resolve any issues in real-time.

These are just some of the benefits you can enjoy from deploying a VoIP system. VoIP is very flexible and has a lot of potentials. To learn more about how VoIP can help you achieve your business goals, contact one of our dedicated VoIP experts at 1-800-398-8647 today!
