What is a VoIP Gateway?Definition
A VoIP gateway is a device that uses Internet Protocols to transmit and receive voice communications.
A VoIP Gateway is used to converts voice and fax calls, in real time, between the public switched telephone network (PSTN) and an IP network. Traffic coming in from the public PSTN is fed through a VoIP gateway and converted to digital packets so traffic can be transported over a local area network(LAN) or other IP-based network.
Conversely, digital IP traffic is fed back through a VoIP gateway for conversion back to analog so it can be transported out over the PSTN. In other words, a VoIP gateway acts as a bridge between an IP network and the PSTN.
The primary functions of a VoIP gateway include voice and fax compression or decompression, packetization, call routing, and control signaling.
VoIP gateways are also power packed with additional features such as interfaces to external controllers like Gatekeepers or Softswitches, network management systems, and billing systems.
Key features of New Rock MX gateways:
- SIP and IMS protocols
- Up to 500 routing and call number transformation rules
- Fax over IP using T.38 & G.711 pass-through
- Hot-swappable FXS/FXO interface card
- PSTN failover
- Auto provisioning
- Dual-redundant Ethernet ports
- Dual AC/DC power supplies (optional)
- Up to 512 SIP trunks
- Voice VLAN
- Remote access via New Rock Cloud
- Management with New Rock or third-party Equipment Management System (TR-069)
- Interoperability with popular SIP servers, such as Cisco Unified CallManager (CUCM), Broadsoft, Microsoft Skype for Business (Lync), Huawei IMS, and Asterisk/Elastix
- Class I lightning protection
How to Use a VoIP Gateway?VoIP gateways come in two types: analog and digital.
Analog gateways connect traditional phones to a VoIP phone system, or a VoIP phone system to the PSTN. New Rock gateways HX4G, MX8G, MX60E, and MX120G are all analog gateways, providing 2-to-96 FXS and/or FXO ports.
Digital gateways connect a VoIP phone system to digital voice lines (e.g. an E1/T1) or to connect a traditional PBX system to an IP network. New Rock MX100G-S is digital gateway, supporting 1/2/4 E1/T1 ports and up to 512 SIP trunks.
New Rock MX series gateways are ideal components in many VoIP-based solutions. Now, let’s look at the typical scenarios of deploying them.
Analog gateways convert voice media between FXO and FXS connections and VoIP connections.
New Rock MX series analog gateways include multiple models and each model provides pure FXO ports, pure FXS ports or mixed FXS ports and FXO ports.
The following shows the typical scenarios of deploying MX series gateway.
To connect analog phone lines (trunk lines) to an IP phone system you need an FXO gateway. An FXO gateway only has FXO ports, which are used to connect with FXS port, then translating the analog phone line to a VoIP call. There are a number of different FXO gateways available.
An FXS gateway is used to connect one or more lines of a traditional PBX to a VoIP phone system or VoIP provider. Alternatively, you can use it to connect analog phones to it and re-use your analog phones with a VoIP phone system. You need an FXS gateway because you want to connect the FXO ports (which normally are connected to the telephone company) to the Internet or a VoIP system.
An analog gateway with FXS ports and FXO ports can connect a modern VoIP-only system to analog telephone lines, analog telephones, and fax machines via FXO/FXS ports.
Digital VoIP gateways allow you to convert voice media between PRI (Primary Rate Interface) connections (which run over T1/E1 lines) or BRI lines (UK) and VoIP connections.
New Rock MX100G-S SIP-ISDN trunking gateway is a digital gateway. It is the most cost-effective solution for businesses with a legacy phone system infrastructure which wants to connect to a VoIP network, such as a SIP trunk. It is also great for businesses which have an IP-based phone system and need to connect to the PSTN.
All you need to do is place the MX100G-S at the edge of your network, plug in your existing internet connection to the gateway for VoIP connectivity and the E1/T1 cables from your phone system and the gateway will automatically handle everything to allow voice media to simply work, including fax.
Now, let’s look at two typical scenarios of deploying MX100G-S ISDN-SIP trunking gateway.
-Public Switched Telephone Network T1/E1/PRI to VoIP
A digital gateway can connect a modern VoIP-only system, for example an IP PBX, to a PSTN PRI trunk.
-VoIP Provider to Legacy PBX
A digital gateway can be used to upgrade a legacy business phone system allowing it to use a SIP trunk out to an ITSP. SIP Trunks are more cost-effective than expensive legacy T1 lines.
Pros and Cons of a VoIP GatewayPros of VoIP Gateways
Advantages of a VoIP gateway include:
- Versatility: VoIP gateways include the proven reliability and call quality of a landline, and they also connect those lines to the internet and enjoy VoIP features.
- Cost savings on calls: When your landline is connected to the internet, you can enjoy features like unlimited long distance calling. If you take calls from all over the country, then you might see a huge cost savings over just using landlines.
- Mobility: Most of the leading VoIP services offer mobile apps for making and receiving calls. This means that you can take your business phone number with you wherever you go on your Android and iOS device.
Cons of VoIP Gateways
Downsides of a VoIP gateway include:
- Setup headaches: If you don’t know a lot about computer networking, then you will likely find setting up a VoIP gateway to be very difficult.
- New businesses: While VoIP gateways are extraordinarily helpful, they aren’t all that useful for new businesses, solo workers, or freelancers with no existing landline infrastructure. Because if you are a newer organization and do not have a landline phone, it is much more affordable and intuitive to set up an all-VoIP network that runs entirely over the internet.
- Service outages: If you lose internet service, you will have to disconnect your landline from the gateway device and reconnect it to your phones manually.
Now, you should have known about why someone would use a VoIP gateway.
One reason is of course the cost. It can be very expensive to change over an entire office to VoIP.
Besides the cost of new phones, there is the PBX infrastructure, the IT support costs, and the time and money it takes to train everyone on the new equipment. Also, as referred in the cons of VoIP gateways, despite every effort to keep servers up and running, sometimes VoIP gateways do fail. But, the good news is that many VoIP gateways have PSTN failover mode to switch to the PSTN if the internet is unavailable. A business that relies heavily on fax machines may also be hesitant to discontinue their legacy phone service. For these reasons, some businesses favor a “hybrid” approach, combining their on-site equipment with VoIP gateways to get many of the advantages of VoIP while still retaining the reliability and familiarity of their existing equipment.
What is the Difference between a VoIP Router and a VoIP Gateway?You would have seen a term “VoIP Router” and wondered what the difference between it and a VoIP gateway.
In fact, a VoIP Router is an integrated voice/data networking device combining a Voice over IP (VoIP) gateway with a NAT router providing for Toll Class voice quality, IP Sharing and manageability from a single, intuitive yet powerful user interface.
In simple terms, VoIP Router is a combination of a router and a VoIP gateway.
