Replace existing telephone lines with SIP Trunks and
benefit from over 70% savings on ISDN costs and some of
the UK’s most competitive call tariffs.
InTechnology’s SIP Trunking solution has the power to deliver immediate and major cost savings to your
existing phone system, and with minimal risk and disruption. By removing your ISDN30 lines and routing call
traffic over your MPLS network, you no longer have to pay for ISDN30 line rental – usually over £5,000 per year
per line – and call charges can be up to 45% less than what you pay today.
It also gives you access to the many benefits of hosted IP Telephony, such as disaster recovery for voice and
remote working. You can still keep your existing PBX telephone system - we just replace your ISDN lines with
our SIP Trunk solution. There’s no need for management or maintenance because we do it for you.

process for you.
