SIP the modern alternative to ISDN30
Introduction For many years ISDN30 has been the only way to provide telephony to large buildings. The technology works and is tried and tested, however it is relatively expensive and inflexible SIP trunks are the modern alternative to ISDN30. Calls are carried over IP networks using your data connectivity rather than the conventional Telecoms network What are the benefits of SIP? Our SIP trunks are certified for use with Microsoft Lync Flexible numbering - eg businesses can work from London on a Glasgow number Supports multi sites, allowing ISDN Line rationalisation Optional Free calls to UK fixed destinations including 01, 02 and 03 number ranges Full business continuity model for businesses without Remote Call Forwarding charges Scalable on a per channel basis Can be utilised with existing customer premises equipment Offers full emergency services support 2
How does it work? AdEPT simply connects a 'pipe' between the customer's site and the SIP network Business grade voice and internet services can be provided via one managed access connection when delivered over Ethernet providing a complete IP access and SIP Trunking solution and is delivered as an end to end service with an availability guarantee, voice channel guarantees, and a guaranteed time to fix Considering moving to SIP? SIP is ideal for businesses that are: Moving premises out of the local area and want to keep their number - no expensive call forwarding services Looking for a disaster recovery solution with a resilient phone service to cope with any emergency Customer service driven where a local area presence is important across the UK and multiple UK numbers can be delivered into one single service centre Currently utilising a single or multiple ISDN 30 at one or multiple sites and are looking to rationalise the number of concurrent calls to the PSTN 3
