SIP trunks offer high quality telephone connections. They save money, suit organisations of all sizes and can easily be enlarged or modified.

SIP makes it easy to manipulate outbound numbers. We can set up non-geographic numbers and geographic numbers for you. This means you can give your overseas customers a number that is local to them and charges local call rates: their calls are routed internationally to your staff wherever they are.

If you have multiple sites, you can use SIP trunking to reduce the number of Private Branch Exchanges (PBXs) you maintain. You can centralise and distribute calls more effectively too.

ISDN technology is being phased out by BT and will be switched off by 2025. Radius Connect can help you plan ahead. We specialise in replacing obsolete IDSN phone lines with SIP trunk systems.
