SIP Trunking allows businesses with legacy phone systems to benefit from the features and cost savings of IP telephony. By simply connecting existing infrastructure such as a PBX or phone system to the public telephone network with a SIP Trunk, businesses can use a single network for both data and voice saving £1000s each year on ISDN lines and call costs.

Why integrate a SIP Trunk with your existing telephony estate
Your business could be looking to expand into new sites, wanting to connect existing telephony systems or make use of your legacy telephony systems whilst benefiting from the features of IP telephony. SIP Trunks allow you to get the most out of your existing investments by facilitating an IP-enabled traditional PBX to deliver a full range of IP telephony features.
These features can provide improved business continuity, for example, using a SIP Trunk, incoming calls can be quickly redirected to another location, or a number of locations, from a web-based portal. You can also provide staff with the ability to redirect their personal phone number to any handset, such as a home number, so that they can continue to work even if there has been a major incident.
Also, SIP Trunks don't have to replace all ISDN lines, they can be installed simply to meet extra demand or for testing purposes; their inherent flexibility allows effortless scaling-up of capacity without affecting existing infrastructure.
