In previous tutorial GNS3:How to Setup CME SIP trunk to VOIP SIP Service Provider – Part 1, my focus was to register CUCME as a SIP User Agent Client(UAC) to a Internet Telephony Service Provider (ITSP). In this tutorial, I will show you the steps needed to setup CUCME for routing VOIP calls outbound as well as inbound call setup. This tutorial will also cover some of common mistakes and steps that cause VOIP calls to fail over the SIP trunk primarily the “Unknown Number” error message.

Remember, you will need a SIP VOIP Internet Phone Service Account in order to setup this tutorial .If you haven’t signed up for an account yet , get yourself a Free SIP ITSP Signup account here before moving forward.

Here are few things that i will cover in this part :

  • Setting up Inbound and Outbound dial-peers for incoming and outbound calls
  • Configuring Voice Translation Profiles for modifying the ANI(caller-id) and DNIS(Called Number)
  • Configuring CUCME setup to route all inbound calls to an Operator Extension
  • Testing and Verification using ‘Click2Dial‘ method (Simulating an Outbound Call)
  • Addressing a “MOST often-made” configuration mistake and its remedy.
