SIP Trunk, SIP Trunks, SIP Trunking
Cloud Communications - SIP Trunking
SIP Trunking provides a real alternative to traditional PSTN and ISDN telephone lines. Our SIP Trunking Service is just £2.00 per channel per month rental and calls to UK local and national numbers are 0.99 ppm and calls to UK mobiles are just 4.5 ppm. Our SIP Trunking service runs over s standard broadband line which can deliver up to 6 simultaneous calls, so with the cost of a dedicated VoIP Broadband Service and the SIP Trunk rental for under £55.00 per month you can have the equivalent of six telephone lines which are compatible with all types of telephone system that can use SIP Trunks. Whether you need a SIP Trunking service for your Asterisk or 3CX IP PBX, or need to utilise the VoIP capabilities of your Panasonic, Siemens, Avaya, Samsung, LG, Toshiba or other brand of phone system then our business quality SIP trunking services are for you.
Even if you don't have a VoIP compatible phone system you can still take advantage of our low rates and line rental by installing a VoIP gateway which will allow you to route calls from your phone system across the internet to our SIP Trunking service. For small business users with Analogue or ISDN2e telephone lines we can supply the Onestream VoIP gateway which offers VoIP connectivity for SIP Trunks as well as branch office connectivity for free calls between offices. The Onestream Gateway also provides GSM gateway services enabling calls to be delivered directly over the mobile phone network with the advantage of low cost and even free calls to mobile phones depending upon the tariff used for the SIM cards which are inserted inside the Onestream gateway.
Line Rental Costs
Our SIP Trunks are charged at just £2.00 per channel per month, with no extra rental charge for DDI numbers.
Calls between offices and homeworkers using our SIP Trunking Service will be free of charge.
UK Local and National Calls - 0.99 ppm
Calls to UK Mobiles - 4.5 ppm
Using SIP Trunking, if you decide to move offices, you can take your BT telephone number with you. This is major benefit of the service. For example, if you are located in London with a 0208 or 0207 number, and move to High Wycombe, you can keep your current telephone number by Porting it to our VoIP network and using SIP Trunks.
A major benefit of using SIP Trunks is the ability to use geographic phone numbers for most UK exchanges, either from your present location or numbers from exchanges around the country.
For example, you are based in Birmingham and require a local presence in London, Manchester and Paris. You will be provided with 0121, 0161 and 331 numbers. The calls from these destinations will be routed to you via your broadband connection. The good news for you is you will not require 0845 or 0870 numbers, and your customers will not have to pay the inflated rates for dialling 0845, 0870 and 0871 numbers.
Why SIP Trunking ?
SIP Trunking provides the ability to make and receive telephone calls over the internet. Within the next 10 years, 90% of telephone calls world wide will be made over the internet.
SIP is a world wide internet protocol for establishing and maintaining multi-party, mixed media sessions over converged networks. SIP enables the creation and deployment of feature rich services that go far beyond simple VoIP calls. SIP provides an open programming protocol for voice, text and video applications.
SIP is the signalling protocol which allows mixed-media sessions of text, voice and video applications using existing devices, including PC/laptops, PDA's and future smart phone technology.
Voice Calls using Microsoft instant messaging and the 3G GSM network are both based on SIP.
At the residential end of the market, companies such as Skype have had 100 million downloads of their software; millions of people are making free calls between friends and family over the internet across the world.
As the commercial version of the residential product, SIP trunking is more resilient and will interconnect with the present voice networks worldwide.
SIP trunking has the full backing of Ofcom (the telecommunications governing body) which has allowed more flexibility compared to the present voice network.
SIP Trunks and VoIP Calls - FAQ
Can I use my present broadband connection?
This depends on the size of your broadband and how many simultaneous calls you want to make over the connection. The size of a SIP voice call is 20Kbitps, so if you have an upload of 256Kbitsps, you could have 20 calls (without any additional data) over one connection.
Can I discontinue my present lines?
We would always recommend you keep a percentage of your analogue or ISDN telephone lines as back up. In the event of your broadband connection going down, we will route calls to an alternative telephone number/s. Most VoIP Phone systems are configured to use existing Analogue and ISDN Telephone Lines as well as SIP Trunks.
Do I need to change my telephone System ?
Many new telephone systems will support SIP trunks; we have tested, and are approved by most manufactures. We can provide conversion units (VoIP Gateways) which connect to your existing telephone system to convert analogue / ISDN trunks to SIP Trunks. This will allow you to take advantage of SIP Trunks and VoIP Calls without upgrading your current telephone system.
Are there any setup charges?
Some services have FREE set up and other SIP trunk services have a small set up charge. To get details of the services we provide and their set up and rental charges visit our SIP Trunk Pricing Page
How do I port my numbers?
There is a simple form to be completed which we then send to BT, the process takes 20-30 working days.
How Resilient is the VoIP network?
The major benefit of the internet is there is no single point of failure. As a company, we have equipment based in seperate locations, should one connection fail the call will be automatically routed to an alternative location.
