Since SIP is the world for telephony now. There were days where ISDN E1 T1 PRI’s were used. Those technology cost lot and lead to heavy investments for companies. Not only the costs, but also for Administrators to manage. Since the SIP has emerged and slowly the industries has moved forward of subscribing to SIP trunks and eliminating ISDN services.
I have seen many users in support forum asking on SIP trunk requisites what is required from service provider to setup SIP trunk. Here I have simplified for you.
I have prepared this document referring to multiple documents and based on my experiences I am sharing with rest of the world. Keep SIPping…!
Note: This document is to understand the list of pre-requisites required to be gathered from service provide It does not cover anything except sip trunk pre-requisites.
Please refer in the attached excel sheet.
