VoIP - Phone Calls Over the Internet
VoIP is an acronym for Voice Over Internet Protocol, or in more common terms phone service over the Internet. If you have a reasonable quality Internet connection you can get a phone service delivered through your Internet connection instead of from your local phone company which dramatically reduces your phone call costs and if its another VoIP system the calls are FREE.
VoIP makes easy some things that are difficult to impossible with traditional phone networks. - Incoming phone calls are automatically routed to your VoIP phone where ever you plug it into the network. Take your VoIP phone with you on a trip, and anywhere you connect it to the Internet, you can receive your incoming calls.
SIP Trunks & Broadband
SIP and SIP trunks is an on-premise solution for a telephone system that will use virtual phone lines rather than physical wires. SIP is suited for larger businesses as it can prove to be more cost effective if there are a lot of users but there is a maintenance implication.
Hosted VoIP is cloud-based and best suited to small-medium sized businesses who are looking for the functionality and scalability of a phone system with no extra maintenance charges. Each user has their own line and calls are routed through the internet.
Shop -Telephone Hardware
Cost-effective and designed for a range of requirements, from light phone users all the way up to enterprise users and managers, offering superb value with an outstanding level of functionality and versatility.
What do i need to start making VoIP calls?
1 - Broadband internet connection
The more call volume you have the higher the bandwidth you will need. If you have a low call volume then a 100Mbps connection should be plenty of bandwidth for you, if you are a high call volume user then you will need to look at a fibre connection. See our broadband packages
2 - Wired Ethernet router
You have a ton of options here but your budget will likely decide this one. I’d suggest a decent VPN router that has QoS and a good amount of concurrent connection volume. The VPN function will come in handy if you want to use your VOIP system from a remote office or home office. view our router options.
3 - PBX Server
We have 2 option for the PBX all depending on your requirements and Tech knowledge.
Option 1 is a cloud hosted PBX, this is the cheapest and easiest option as it requires very little configuration and no hardware installation. more.....
Option 2 is a Onsite PBX server, this option is a little more expensive and does take some technical knowledge to set up and maintain and bring very little benefits over a cloud hosted PBX. more.....
4 - VoIP Provider
VOIP Provider. This is a service that you need to subscribe to, much like a normal phone company, that allows you to actually make and receive calls outside of your office. Without one of these you’re only able to dial other extensions within your office. see our packages to find the option that best suits your usage
5 - VoIP Phones
You will need a VoIP compatibility phone such as Grandstream, if you have a smart phone you can download an VoIP app which will allow you to make and receive VoIP calls. Grandstream wave and ZoiPer are the best smart phones apps we have found. view our range of VoIP phones
SIP trunks are more flexible & cost effective than ISDN Lines
SIP trunk (VoIP) compared to ISDN
SIP delivers less costly, more reliable connectivity than ISDN over an IP connection. It can save up to 50% on line rentals and 25% or more on call costs.
SIP Perfect for medium or large organisations with multiple sites, not only will you save on your line rental and call costs, but you’ll get free internal calls within your organisation and a whole host of great features.
SIP trunks are ideal if you are moving, upsizing or downsizing and want to keep your existing numbers. Scale up lines during busy periods and back down again afterwards. You can add lines, take them away, split calls at any time. You are always in control.
|Savings||Saves up to 50% on line rentals and 25% on calls||Expensive|
|Flexibility||You’re in control. Add lines, take them away, split calls – it’s up to you||Sorry, can’t do flexible|
|Control||Choose how and where you want calls delivered. Make changes instantly||Changes take months. At the mercy of suppliers|
|Future||Well mapped out and ready for Voice/Data convergence||Going nowhere fast|
|Contingency||Handles emergencies with ease. Reroute calls to backup sites in seconds||Hope nothing bad happens|
Is SIP secure?
We only employ IP authentication.
We can build private layer 2 VLANS to customer devices that support RFC 1918 addressing. On this basis the endpoints cannot be seen from the public Internet.
Traffic patterns on the Session Border Controller (SBC) are monitored for anomalous behaviour and appropriate alerts deployed
Rate and channel restrictions are place on all endpoints to ensure that the SBC cannot be overloaded.
All SBC’s are deployed in fully secure premises
SIP trunking SBCs and Portal are penetration tested by professional 3rd party consultants to offer assurance that the security is fully effective
In addition, our free fraud protection service limits exposure to fraudulent activity from endpoints that have fallen victim to hacking or excessive unauthorised call spends.
How do we ensure quality?
Quality is assured through:
Proactive monitoring and management of quality of service functions across our entire network including, but not limited to, Post Dial Delay (PDD), Answer to Seize Ratio (ASR), Network Efficiency Ratio (NER), Mean Opinion Score (MOS), Perceptual Analysis of Speech Quality (PESQ) Score, Call Closure and Error codes for C7 and SIP signalling, Jitter, Latency, Packet Loss, Trunk and Circuit occupancy, uptime and trends
Proactive call testing and analysis for all platforms and services
Appropriate and timely alerts of potential issues and ‘hot spots’ to our 24×7 Network Operations Centre
