Always inspect the Syslog for any problem you may encounter; in many cases, the cause
appears there.

Problem Probable Cause Corrective Action
General Voice Streaming Problems
Attempts to perform voice streaming
operations results in each Syslog containing
the string: 'VS_STACK_NOT_ACTIVE'.
Voice streaming is not
enabled.
Enable voice streaming
by loading an ini file
containing this entry:
EnableVoiceStreaming =
1
HTTP Voice Streaming Problems
The last half-second of an announcement is
not played, or a record operation terminates
abnormally and the Syslog displays the
following: 'VSReceiveFromNetwork:
VS_CONNECTION_WITH_SERVER_LOST'.
(The problem has been experienced with
Apache version 2.0.50 on Solaris 9.)
The Web server is closing
the virtual circuit at
unexpected times.
Increase the Apache
KeepAliveTimeout config
parameter. Try to
increase it to 30 seconds
or longer than the longest
announcement or
expected record session.
NFS Voice Streaming Problems
Announcement is terminated prematurelyand
the Syslog displays the following: 'NFS
request aborted … networkError'.
The AudioCodes media
server has lost
communication with the
NFS server. A network
problem or some problem
with the NFS server
exists.
Fix the network problem
or NFS server problem.
Ensure that the NFS
server is not over-loaded.
Unable to play announcements from an NFS
server and each Syslog displays the
following:
'Unable to create new request, file system
not mounted'
'NFS mount error …'
Either there is a problem
with the NFS server, the
network, or configuration
of the media server or
NFS server.
Fix the network problem
or NFS server problem.
Check the configuration
on both the media server
and the NFS server.
Record is terminated prematurely and the
Syslog displays the following: 'VeData: no
free buffers, req=16'
'Unable to play announNFS request aborted,
reqid=16 cid=16 error=noRecordBufferError
reqtype=vsHostRecord state=recTransfer'.
This occurs when the
media server is receiving
audio faster than it can
save it to the remote NFS
server. Either there is a
problem with the NFS
server, the network, or
configuration of the media
server or NFS server.
Fix the network problem
or NFS server problem.
Check the configuration
on both the media server
and the NFS server.
