Session Initiation Protocol (SIP) Trunk is a service that lets you use your existing PBX system over a VoIP network to make and receive calls.
SIP Trunks are much cheaper than the old analog circuits that traditional enterprise phone systems use. They also maintain or exceed the level of call quality that businesses expect from their phone service while saving you money.
SIP Trunking is a good option for a business that already has a PBX system. If your business already has the hardware, it is easy and inexpensive to setup a SIP Trunk. One SIP Trunk can connect your phone lines to your existing hardware. Your business will also now save money by using the robust Nextiva VoIP network instead of a traditional phone line.
SIP Trunks can work with a SIP-ready PBX. They can also be made to work with traditional analog or key systems with an IAD (Integrated Access Device).
