Description (partial)


Incident report generated and "application failed" alarm raised with the following message:

"An unexpected error was detected in this should never happen" 

The impact of this bug is that it may cause the phonebook server (or provisioning server) to crash.

This process is automatically restarted by the app in a matter of seconds so there is a limited impact on the customer.


The ACR is due to a bug in twisted sip module. It raises a runtime error if a
message transmission is aborted while receiving a message, which isn't right.
