1 SIP the modern alternative to ISDN30

2 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
