Columbus provides total flexibility when it comes to the numbers you want to use for your SIP Trunk service. You can keep your existing numbers or get new numbers. You can also extend your business reach and use any local area numbers no matter where you are located. With our CLI Flexibility service you can also use any telephone number to display to called parties. One of the biggest benefits is that unlike traditional business telephone lines, you won’t lose your telephone numbers if you move out of your local exchange area.
Compared to BT ISDN30, using Columbus Business SIP Trunks will save you a very significant sum on installation costs. This could be a saving of 90% or more based on the installation of a BT ISDN30 bearer with 30 channels on a 12 month contract term (BT pricing checked 03/12/15). One of the other major benefits for UK SME customers is the immediate and significant reduction in operating costs. By utilising Columbus Business SIP Trunks you could save up to 50% on line rental compared to BT ISDN and up to 25% on call charges. Customers with multiple sites also benefit from free calls between sites.
Compared to traditional line services, the benefits of SIP Trunks are many and varied which includes reduced set up costs, faster service delivery, better value line rental and call charges, greater service and telephone numbering flexibility, vastly superior Disaster Recovery capabilities and much more besides. Columbus provides end-to-end support for our SIP Trunk and access solutions meaning one supplier for PSTN lines, broadband, router, SIP trunks, telephone numbering, diverts and Disaster Recovery plans saving you hassle, time and money.
If you want exactly 3 lines, you can have just that. You only pay for what you need on a simple channel rental basis and the minimum number of channels you can order is just 2 compared to 8 on ISDN30. This is great for businesses that would otherwise pay for traditional line services they do not use or require but are forced to, due to the minimum channel commitment on traditional ISDN30 services. For larger businesses that need to scale the number of channels required up or down and do so quickly during peaks and troughs in business, SIP Trunks are perfect for this scenario. You can have as many SIP Trunks as you require without any additional charges to increase or decrease the number of channels required.
Unexpected events such as snow, floods and power failures won’t disrupt your business. Because our SIP Trunk service sits in the “cloud”, the service provides Disaster Recovery features that allow your organisation to carry on receiving calls whatever the occurence and nature of the unexpected event. Traditional business lines just cannot provide the same level of service or functionality without going to great expense.
Columbus Business SIP Trunks connect your sites directly to the Columbus IP network via a broadband access service. This provides a reliable and dedicated means to carry voice calls across the public telephone network. The service is delivered as an ‘end-to-end’ service with an availability guarantee, voice channel and quality of service guarantees.
Compared to ISDN lines the Columbus SIP Trunking service is less costly per channel and more flexible in how and where geographic telephone numbers can be used. It’s also quicker to deliver and provides very robust business continuity features as standard. The service can support businesses that require as little as two channels which operate small business phone systems to an unlimited number of channels for large organisations and contact centres.
- 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.
- Not only will you save on your line rental and call costs, but you’ll also benefit from free internal calls which is great for businesses with multiple sites.
- SIP trunks are ideal if you are moving, upsizing or downsizing and want to keep your existing numbers. You can 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.
- SIP trunks can handle emergencies easily. They are inherently disaster recovery / business continuity ready, letting you route calls to alternative locations quickly and easily.
Columbus Business SIP Trunk solutions offer robust business continuity options not available on ISDN to ensure your business never loses any calls. The Columbus active/standby and load sharing SIP Trunk solutions are designed to cope with any potential downtime situation; whether you need to keep your organisation running during an unplanned emergency without the high cost of call forwarding or simply need to balance call volumes between sites during busy periods, Columbus’ ‘resilient design’ SIP Trunk solutions deliver the continuity of service you need to keep your business operational whatever the circumstances.
