Shoretel VoIP configuration for Vocia VoIP-1

Biamp’s VoIP-1 allows Biamp Vocia systems to utilize Voice-over-IP (VoIP) systems that adheres to the SIP (Session Initiation Protocol) standard. The interface permits live, real-time paging using any page code within the Vocia system using the VoIP telephone extension as the paging source. The VoIP-1 is available with one or two VoIP network ports. Each port will support up to two lines. This document details the steps required to configure a Shoretel system to work with Biamp’s VoIP-1. For information regarding the parameters not covered in this article, please refer to the Vocia help.

Preliminary steps

The first step in setting up the ShoreTel system is to verify that the proper amount of SIP licenses are in place. Each VoIP-1 port can support up to two lines and 2 ports may be present in a single VoIP-1 (VoIP-1-4).  The ShoreTel system will require a SIP Phone License for each extension assigned to the VoIP-1.  The steps to verify the license count are detailed below.  If it is discovered that there are not enough licenses available, contact the VoIP Admin. 


  1. License Requirement ListGo to Administration ->System Parameters-> Licenses -> Requirements
  2. ShoreTel SIP Phone License Purchased must be equal or greater than the number of lines to be assigned to the VoIP-1.  Purchased Licenses will move to Configured Licenses after the ShoreTel system has been fully configured.
