Switching equipment congestion
The call could not be completed because the switching equipment generating this Cause Value

[0x2B/0xAB] -
Access information discarded
The network could not deliver access or user information (such as low-layer compatibility or
calling-name information) to the remote endpoint for any one of various reasons. For example,
the call interworked from ISDN to non-ISDN facilities, or the remote end does not support
delivery of such information.
