Some of the PBX vendors we work with
SIP Trunks are a form of media transfer that connects your premises directly to the Public Telephone Network. SIP (Session Initiation Protocol) is used to deliver voice, video and communications data over a SIP-based private branch exchange, commonly known as IP-PBX and is the backbone of unified communication solutions. Trunks are compatible with all the leading PBX hardware and this simple transfer to SIP offers cost-saving benefits with future-proofing and flexibility as added benefits.
SIP Trunks are the fastest growing telephony line for businesses looking to save money and add a layer of resilience to their existing telephone system. With SIP there is no need to upgrade systems as the ISDN channels are simply switched to SIP for internet-based calls, video and unified communications. SIP trunks are the perfect transition to IP-based calls using an existing system, without jumping to full VoIP (Voice over Internet Protocol).
SIP trunks are added to the configuration of an existing phone system with IP access enabled. The typical digital system running over ISDN2 or ISDN30 is switched to SIP using the ID for example sip:0-800-043-0800@tw.example.com. This will pass traffic over the internet and any traditional copper ISDN channel can be removed to save money on rentals and call charges.
