SIP Trunking

4net is able to provide market leading SIP trunking service, which enables IP connectivity and full “telephony” breakout services. SIP trunking provides communication flexibility and disaster recovery and can be a cost effective alternative to ISDN.

Number portability – allowing businesses to relocate their office anywhere in the UK and keep their number.

Number flexibility – supporting DR plans at a fraction of existing ISDN costs.

Ease of system expansion – an additional number of SIP channels can be added to a site at a fraction of the time and cost that deploying ISDN would entail.
