SIP Trunking provides the customer greater flexibility with their inbound and outbound communication needs whilst offering a significant cost saving over traditional ISDN and PSTN phone lines.

With British Telecom’s announcement in 2015 that they will be shutting down the ISDN network in 2025 SIP trunking is becoming a reality for many businesses and individuals as they update their telecoms equipment or the extra demand in recent times for home working.

Moving your phone numbers and lines (Known as porting) to use on SIP trunks also helps give your business some continuity for the future as you will be able to keep your contact telephone numbers in the event of an office relocation.

As part of our commitment to providing as much of the proposed solution in house, TRILAN I.T. also provide SIP trunks for use with all IP based PBx’s and even a singular IP Phone.

We can provide SIP trunks based on either registration by IP or by username and password.
