SIP Trunks enable you to connect your IPPBX to your Internet Service Provider via Session Initiation Protocol (SIP). In a nutshell it’s a replacement for your old PSTN line. SIP Trunks are more cost-effective than PSTN lines as interoffice calls and calls to remote teams are free of charge. In addition, with the use of SIP Trunks your customers can call you for free using 1300 or 1800 service numbers.
Our SIP Trunking services operate on our extensive Ethernet network and provide superior scalability in comparison to traditional ISDN. Our SIP Trunks’ access is restricted to our customers’ systems ensuring call quality and peace of mind.
13,1300 & 1800 numbers allow your customers to call you toll-free. At 3SIP Services we offer highly competitive rates for inbound 1300/1800 number services, with a small one-off set up fee and great customer service based right here in Australia.
Whether you require a new local number from a single to blocks of 10 to 100+ ranges or wish to keep your existing number* and transfer/port it to your SIP Trunk, at 3SIP Services we offer you both options.
