SESSION INITIATION PROTOCOL (SIP)

Telecommunications are a key component of “unified communications”. While integral to the smooth running of operations and allowing your business to be fully connected at all times, Telecoms no longer require a phone line. Enter SIP.
We provide business telephone lines, from single lines to multi-site installation, we have a range of solutions to suit your individual requirements. IP Direct, Local Loop Unbundling and SIP Trunks are just a few of the solutions we provide to maximise your communications.

Silver Lining are able to assist with your planned migration from ISDN. In addition we have a dedicated IP connection from our highly secure core data centres, complete with SLA to ensure you never miss a call even if your office is compromised.
