What is SIP Trunking?
SIP Trunking is the replacement for traditional ISDN, giving businesses the same access to the PSTN, but providing a more flexible and lower cost alternative.
SIP Trunks support all inbound and outbound voice calls via IP.
SIP connects your telephone system PBX to the PSTN via broadband, ethernet or private circuit into a national network. Our SIP Trunks work seamlessly with each of the leading IP PBX brands in the UK market.
Benefits of SIP Trunking
Compared to ISDN, SIP trunking is less costly per channel and more flexible in how and where geographic telephone numbers can be used. It’s also quicker to install and provision and, as standard, it delivers extremely robust business continuity.
The service can support connections ranging from two channels for small PBX-equipped businesses, to an unlimited number of channels for large enterprises and contact centres.
Flexibility with phone numbers
SIP trunking enables you to move office and keep the same geographic number without any ongoing call-forwarding costs or those associated with producing new company stationery.
For businesses with multiple sites, SIP trunking provides the opportunity for line rationalisation and reduces the number of PBXs you need to maintain - while retaining full control of the numbers associated with your business.
SIP trunking provides a phone service that will cope with any situation and give you business-grade resilience for your telephony. Whether you need to keep your business running in a disaster or emergency or you need to load balance your calls between sites during peak hours, SIP trunking delivers.
If your office has to be temporarily relocated in an emergency, this can be achieved quickly and cost-effectively with SIP trunking to keep your business working.
IP connectivity costs less than ISDN with lower call costs, free internal calls between extensions and offices and lower line rental costs for multi-sites. Also, no expensive call-forwarding costs are required should you relocate or need to divert calls in the event of a disaster.
Compatible with Skype for Business™
Our SIP trunks are integration tested and approved to interoperate with Skype for Business, allowing you to directly connect to the platform to make external calls.
