Verification Steps; Verify Call Flows - Avaya 1000E Application Notes

9. Verification Steps

9.1. Verify Call Flows

The call flow pattern for calls coming to the Meeting Exchange from the Avaya Aura
Communication Server (CS1000E) will move through the following steps:
W - Indicates potential WireShark tracing points.
1. Call from IP phone on the Avaya Communication Server (CS1000E) dials 23600 to reach
Meeting Exchange. The endpoint can be monitored via a WireShark trace or via trace
tools available in the CS1000E. The CS1000E looks up the number in Distant Steering
Codes and directs the call to the Route that indicates an E1 link to the Dialogic IMG
1010.
2. Dialogic IMG 1010converts the E1 traffic to a SIP request after looking at its own
Routing Table and determines the call should be routed to the Avaya Aura Session
Manager. The traffic in and out of Dialogic IMG 1010 can be monitored via WireShark,
as well as the built in Call Tracing Log. SIP traffic to/from Dialogic IMG 1010 will also
be visible in the Session Manager traceSM tool.
3. Session Manager receives the SIP INVITE from Dialogic IMG 1010 and looks up the
digit pattern entered and determines where next to send the call based on the
programming of the routing policy i.e. send call to SIP Entity ―Meeting Exchange‖. This
traffic can be monitored via the traceSM tool.
4. Finally the Meeting Exchange receives the SIP INVITE and compares to the Call
Branding table to determine if the number is recognized. If the dialed number is
recognized, it will respond with a request for the caller to enter a PIN number. If not
recognized, the caller will be placed into the Enter queue and will hear music. Some
limited tracing is available directly on Meeting Exchange.
