DPA 7630 Known Problems
Bug ID
Summary
Explanation
CSCdr83003
The FTP server does not
require a username or a
password.
The DPA 7630 does not require user names and
ships without a set or enabled password. Once you
set a password, however, the DPA 7630 requires that
you use it.
If you are able to access FTP without entering a
password, then no password has been set. (The FTP
server uses the enable password if one has been set,
otherwise it uses the login password if one has been
set, otherwise it uses no password.)
To set the password, complete the following
procedure: From the main menu, select Configure >
Passwords, select Login password, then enter the
new password.

DPA 7630 Known Problems and Errata
Table 1
DPA 7630 Known Problems (continued)
Bug ID
Summary
Explanation
CSCds25389
Voice mail hunt groups
containing more than 13
extensions can cause voice
mail access to fail with an
error tone.
By default, the Cisco CallManager supports a
maximum of 12 forwarding hops, leading to a
maximum of 13 extensions in any one hunt group.
CSCds34576
Call transfers between an
Octel 200 series Voice Mail
System and a
Cisco CallManager are
occasionally not working.
To work around the problem, do one of the
following:
•
Set the “ForwardMaximumHopCount” System
Parameter to more than 12. (Refer to the section
“Setting the Hop Count” on page 3-12 of the
Cisco Digital PBX Adapter 7630
Administration Guide for instructions on
setting this parameter.)
•
Divide the DPA 7630 into several hunt groups
(possibly all in the same forwarding chain) to
improve load balance.
Call transfers between an Octel system and a
Cisco CallManager can fail because of a
discrepancy between the delay expectation built into
the Cisco CallManager and the speed with which the
Octel system dials an extension.
To work around problem, set the Octel 200 system
parameter 254 to “ED.” This setting forces the Octel
system to wait for a dial tone before transferring a
call.
CSCdr83478
The console locks up and
requires a power cycle to
resume functioning.
In rare circumstances, a terminal program
connected to the console port of the DPA 7630
might lock up. The DPA 7630 itself continues to
function correctly.
To work around the problem, restart the terminal
program.

DPA 7630 Known Problems and Errata
Table 1
DPA 7630 Known Problems (continued)
Bug ID
Summary
Explanation
CSCdr84798
The DPA 7630 produces runt
packets (under 64K) when
speed and duplex
combinations are configured
on an Ethernet card in a
Cisco Catalyst series switch.
The DPA 7630 does not support full-duplex
Ethernet operation. Runts may be produced if you
connect the DPA 7630 to an Ethernet hub/switch
port that is set to operate in full-duplex mode.
CSCdr90825
Sending a file to the
DPA 7630 takes considerably
longer than receiving the same
file from the DPA 7630.
This is expected behavior. It takes longer to write to
the Flash-based filing system used by the DPA 7630
than to read from it.
CSCds34595
When set to perform
supervised transfers, an Octel
250 Voice Mail System
sometimes inaccurately
reports that an extension is
busy.
The Octel system sometimes identifies as busy an
extension that is actually unavailable. This occurs
when the Octel system is set to perform supervised
transfers to an extension, and when that extension is
configured to forward all calls to voice mail. Under
these circumstances, the Octel system cannot
correctly identify why a call is forwarded to voice
mail.
CSCds38975
Using the Cisco IP Phone
7960 in speakerphone mode at
a high volume and in
conjunction with the
DPA 7630 can cause some
dual tone multi-frequency
(DTMF) digits to be sent
twice.
Some DTMF digits are sent both in-band (caused by
acoustic coupling between the speaker and the
microphone) and out-of-band. As a result, the Octel
Voice Mail System receives the digit twice.
The Message Waiting
Indicator (MWI) feature does
not travel across an
inter-cluster trunk.
MWI commands are not propagated across
inter-cluster links. Therefore, the DPA 7630 can set
MWIs only for those extensions located on the same
Cisco CallManager cluster as the DPA 7630 itself.
CSCdr88571
To work around the problem, use auto-negotiation
or set the Ethernet port to operate in half-duplex
mode.
To work around this problem, ensure that the
Cisco IP Phone operates with a firmware version of
P003D301 or later.

DPA 7630 Known Problems and Errata
Table 1
DPA 7630 Known Problems (continued)
Bug ID
Summary
Explanation
CSCdr93073
Only two simultaneous Telnet
sessions are supported by the
DPA 7630 at any given time.
This is expected behavior. The DPA 7630 does not
accept more than two simultaneous Telnet sessions.
CSCdr93980
Attempting an unsupervised
transfer from an Octel Voice
Mail System to a non-existent
or busy Cisco CallManager
extension results in the caller
being disconnected.
This is expected behavior caused by operational
differences between Lucent Definity PBX systems
and the Cisco CallManager.
CSCds01181
The DPA 7630 does not
support extension numbers of
more than seven digits.
This is expected behavior. Seven is the maximum
number of digits in an extension number supported
by the DPA 7630.
CSCds08331
Time stamps and delta times
in the event log are out of
order or expressed as negative
numbers.
The DPA 7630 maintains time by periodically
synchronizing with a network time source (an NTP
server) and by relying on its own internal timer
between network updates. Because this internal
timer can differ slightly from the NTP server’s time
source, a gradual divergence between the two clocks
can occur, requiring adjustments upon the next
synchronization. These adjustments can cause time
stamps and delta times in the event log to appear out
of order.
CSCds25783
Transfers using the Octel 200
Voice Mail System fail if the
caller presses phone keys
while on hold.
Octel-supervised transfers fail if keys are pressed
while the call is on hold. This is expected behavior
caused by operational differences between Lucent
Definity PBX systems and the Cisco CallManager.

DPA 7630 Known Problems and Errata
Table 1
DPA 7630 Known Problems (continued)
Bug ID
Summary
Explanation
CSCds39732
MWIs (message waiting
indicators) fail to turn off and
the Octel 250 Voice Mail
System disables its MWI
ports.
For MWIs to function properly, the Message
Waiting Timeout feature in menu 6.2 of the Octel
system must be set to the “positive
acknowledgement” setting.
The “negative acknowledgement” setting directs the
Octel system to interpret the lack of a confirmation
tone as an error indication. The DPA 7630 requires
that the “positive acknowledgement” option be
used.
To work around this problem, set the Octel system’s
Message Waiting Timeout feature in menu 6.2 to
“positive acknowledgement.”
CSCds46787
The bootloader XMODEM
doesn't allow en dashes
(“-” characters) in filenames.
The filenaming restriction in XMODEM prevents
image files from uploading with their original or
typical names.
To work around the problem, use FTP to transfer
image files.
CSCdr87999
CSCds50531
Fax messaging fails to work
across a G.711 inter cluster
trunk.
Under certain circumstances, fax messaging across
a G.711 inter cluster trunk can fail.
The Octel Voice Mail System
sometimes fails to answer a
call that you place
immediately after terminating
a previous call to the same
extension number.
If you dial a port on the DPA 7630, then hang up and
dial the same port again quickly, the DPA 7630 fails
to answer and the Cisco IP Phone continues to ring
until you hang up.
Be aware that fax messaging will not work if any
part of the system through which you are sending
the fax is operating in G.729 mode. Verify that your
inter cluster trunk, or H.323-analog gateway, is
registered as a G.711 in the Cisco CallManager.
To work around the problem, configure the
Cisco CallManager to roll the redial attempt to a
new port. Refer to the section “Incoming Calls” on
page 3-6 of the Cisco Digital PBX Adapter 7630
Administration Guide for more information.

DPA 7630 Known Problems and Errata
Table 1
DPA 7630 Known Problems (continued)
Bug ID
Summary
Explanation
CSCds40475
Transfers from a Cisco IP
Phone to a PBX phone via the
DPA 7630 are routed directly
to voice mail.
The DPA 7630 functions properly in a Hybrid
configuration only if the Cisco CallManager has a
route plan that allows the Octel Voice Mail System
to make calls to a PBX system via the
Cisco CallManager.
For example:
•
PBX directory numbers are 5XXX
•
Cisco CallManager route plan is 8.XXXXX
In this case, you must create a route plan for the
Cisco CallManager that accepts the PBX pattern of
5XXX and allows the DPA 7630 to route the calls
over the digital link.
Documentation Errata
The following information was omitted from, or documented inaccurately in the
Cisco Digital PBX Adapter 7630 Administration Guide.
Setting No-Answer Timeout
The following section modifies page 3-13 of the Cisco Digital PBX Adapter 7630
Administration Guide.
When performing supervised transfers, the Octel system expects a certain number
of rings before the call forwards to voice mail. If the call forwards to voice mail
prematurely, the Octel system assumes the phone was busy.
To ensure that the Cisco CallManager system allows enough time for the number
of expected rings on the Octel system, you must set the no-answer timeout. In
Cisco CallManager, you should set this setting to be 6 seconds times the number
of rings. (Six seconds is slightly longer than the ring duration of a Lucent Definity
PBX system.) For example, if you have the Octel system set to four rings, set the
setting in Cisco CallManager to 24 seconds.

Setting Community Strings
The following information refers to the section “Setting Community Strings” on
page 4-15 of the Cisco Digital PBX Adapter 7630 Administrative Guide.
You must assign community strings (“read-only” and “read-write”) using
Configure > SNMP in order to complete the configuration process. By default,
the “read-only” community string is set to public, which provides read-only
access. If you do not set these community strings on the DPA 7630, you cannot
manage the device remotely using the Simple Network Management Protocol
(SNMP).
