SIP Trunking

SIP Trunking is designed for business customers with deployed Internet Protocol (IP) PBXs and IP phones and provides essential telephony features such as local and long distance calling. SIP Trunking delivers voice calls in IP packets so it is easy to add Nextera’s internet, with products such as T-1 or DSL, for a complete managed service. Nextera provides even greater flexibility and opportunity by method of delivery – choose either traditional wired service or Nextera’s 4G WiMax.

Each SIP trunk (voice channel) can be compressed to utilize as little as 35kbps to allow the maximum efficiency of your internet bandwidth.
