Overhead paging can be something of an art. The reason there is not a fixed way of doing this is because there are many kinds of equipment out there. This post will cover paging to an analog trunk port. The equipment being used is an Avaya IP Office 500v2 unit running 8.0.43 firmware,and the paging interface is a Bogen TAMB. Initially,since I had been successful in the past paging to an analog station port,I thought this would be a good approach. However,the engineer I was working with on site said the paging interface only had a loop start trunk port.
Step 1: Create a line group dedictated to the paging trunk port. Go into the analog line properties page. Change the line type to loop start (no ICLID). Make the incoming and outgoing group value something unique like 99. As long as these group values are not being used by another line,you will be fine. Also make sure this line is set to active.
Step 2: Create a short code –choose any available one such as *80 (your system may differ). Telephone number field is ‘.‘(just put in the period,not the single quote marks) and the line group ID is going to be what you set in Step 1. In our case,it is 99. The feature will be dial.
Step 3: Save your changes. Since you probably made changes to the line in Step 1,this will require a system reboot.
You should now be able to dial *80 from any phone an be connected to your paging system.
