Release Update, Rev 62 — January 30, 2008 267
Dialogic Corporation
Known IPY00007879 31659 DM/IP Boards The default nfrm value for user-defined tones on
Dialogic
®
DM/IP Boards is 10. In situations where the
DM/IP Board firmware is being used in a PSTN
environment, this value may need to be lowered if you
are seeing cadence detection failures. PSTN products
(QVS) use a value of 3, but preliminary testing shows
that a value of 5 is sufficient to reduce errors to 0 for
DM/IP Boards.
Known IPY00007701 31594 DM/IP Boards RFC2833 failures occur when using low bit rate
coders at 3-4% failure rate when tone duration is
longer than 2 seconds.
Known IPY00007555 29164 DM/IP Boards The error message (RTP Recv: in
media_RTPUnpack( ) SSRC failed) may occasionally
be seen in DebugAngel when running Dialogic
®
DM/IP
Board configurations.
Workaround: Ignore the message; it does not affect
the application.
Known IPY00007322 29280 DM/IP Boards Call progress over IP will fail intermittently in
applications. If the application performs call analysis to
find out how it was connected (e.g., PAMD, fax) it won't
be able to do it consistently.
Known IPY00006725 31651 DM/IP Boards The multicast transmit address can be set as
addresses other than the reserved multicast
addresses. No error checking is available to prevent or
warn against this.
Workaround: Ensure that only valid IP addresses
(244.0.0.0 to 239.255.255.255) are used.
Known IPY00006467 29048 DM/IP Boards When the host application crashes or is abnormally
terminated (e.g. killed in Task Manager), Exit
Notification does not cancel all events in the Dialogic
®
DM/IP Board firmware. The boards must be re-
downloaded or else the application will fail to initialize.
Workaround: Re-download boards after a host
application crash.
Known IPY00006466 29008 DM/IP Boards ipm_GetSessionInfo( ) returns all zeros instead of
valid information. Explanation: No information will be
returned if an RTP session has not been created, or if
called before an RTCP report has been received
during a session.
Known DM/IP Boards Echo when using Dialogic
®
DM/IP Boards with
Microsoft NetMeeting.
Workaround: Disable the residual speech flag by
setting prmECResSpFlagEnableDisable (parameter
number 0x1b65) to 0 in the config file, then
restarting the Dialogic
®
System Service.
