This section aims to identify any problems in SS7 Support for Blueworx Voice Response, and suggests possible
fixes to them.
Stage 1: Is the SS7 Server working? This test investigates whether the D7 package is present on this machine and checks its current state of operation, by using the following instructions:
Stage 2: Which other machines are present? After completing Stage 1, you should have an SS7 Server machine with a D7 package running. The next stage is to investigate which other machines are present in the SS7 Cluster.
Stage 6: SS7 Adapter checks This stage investigates the presence of SS7 Adapters. Perform the following tests:
Stage 7: SS7 Links. Reaching this stage indicates that the D7 package is functioning correctly on all machines in the SS7 cluster, and that this machine has the correct configuration.
Stage 10 At this stage the following have been tested and proved to be working:
Stage 11: Inbound Traffic This suggests that all the circuits are now working and ready for call traffic, but you need to test that this is the case, as described in this section.
Stage 12: Testing outbound calls Arrange for an application to generate an outbound call, and monitor the SS7 message as before by entering ss7view –message –t. Perform the outbound call.
Redundancy – Blueworx Voice Response client failure. When a Blueworx Voice Response client fails or is taken offline, the associated SS7 Server that is managing its circuits passes responsibility and control to another Blueworx Voice Response client. As a Blueworx Voice Response client that is taking over the circuits of another client cannot perform call control on these circuits (the voice bearers are not physically connected to it), it can only take the circuits out of service in a controlled manner, and thereby ensure no further calls are taken by these circuits.
The effects of call overload Whenever a new application is planned for your configuration, you should carefully consider the call volume or call rate. The planning section earlier in this document describes how to calculate the Link requirements. However, if these are not reviewed when new applications are added to the Blueworx Voice Response system, you might find that the original calculation does not meet the new requirements.
Obscure problems This section describes other miscellaneous problems.
