Прошивка OfficeServ 7070 v4.82 20140807

Сообщение Wi$e 28 авг 2014, 23:21

Прошивка для АТС Samsung OfficeServ 7070, версия 4.82 20140807.
New Version Changes
’14.08.07 V4.82
[Bug Fix]
1. [VM/-/ALL] Block table is broken when the disk is full
<Description>
When the disk is full, it fails to save block table and it is broken. Then backup block table becomes broken, too. So, it does not work when it resets.
<Cause>
This does not occur in normal situation because SVM is designed to leave a small space of disk(over 100Mbytes). But if it’s filled up by abnormal reason, it makes a problem.
Block table cannot be saved. It’s ok, but original block table is broken. Then backup block table is broken, too. So the system does not work, if it resets.
<Resolution>
Saving block table is modified.
It will create a temporary file and save block table to it.
If there is no problem, it will replace old block table with new one.
2. [VM/-/ALL] SVM resets when it repeats to play the prompt does not exist.
<Description>
SVM resets when it repeats hundreds of times to play the prompts does not exist
<Cause>
It’s because the playback thread resource is lost when the prompt is gone.
Resource leak is getting bigger and bigger while it repeats to play the prompt does not exist and the system is stopped or reset.
<Resolution>
SVM will check the file is really available before it plays and although it tries to play the prompt does not exist, it will retrieve the playback thread resources.
3. [VM/-/ALL] DM 8.11 Status Screen and DM 8.9.3 Messaging Activity cannot show over 100,000 messages
<Description>
If total message count is over 100,000, wrong number is played in DM 8.11 Status Screen and DM 8.9.3 Messaging Activity.
<Cause>
The buffer to save message count is overflowed.
It’s defined as 2 bytes, so it can handle max 65535. If it’s overflowed, it displays totally wrong number.
<Resolution>
The buffer to save message count is extended to 4 bytes.
<Consideration>
The message format between SVM and DM is changed. It affects DM 8.11 Status Screen and DM 8.9.3 Messaging Activity.
Previous version of DM(lower than V4.80) is not compatible with latest system software in DM 8.11 Status Screen.(It’s not updated automatically)
You have to use latest DM(V4.80 or later) for that pages.
4. [VM/OS7030/ALL] If the disk is full of messages, OS7030 often resets when it starts
<Description>
If the disk is full of messages, OS7030 resets sometimes when it starts.
So it takes a long time the service to be available.
<Cause>
OS7030 rebuilds message table when it starts, it accesses the disk a lot. The file system of OS7030 is slower than other system, so the page cache is full, then the application stops until the cache data is processed.
So the system resets because it cannot trigger the watch dog timer.
<Resolution>
When it rebuilds the message table, it will flush the cache after processing each file.
<Consideration>
It’s applied only for OS7030. It takes a little more time to boot when it has so many messages.

5. [-/MP20S/ALL] SLI port’s None Status on MP20S
<Description>
When Booting up with only SLI2, SLI3 or A-TRK cards in all slots, last several SLI ports’ port status was changed to ‘None’
<Cause>
In this case, last several SLI ports were not initialized because of internal message queue overflowed.
<Resolution>
Sending meaningless duplicated messages is eliminated.
6. [-/ALL/ALL] Cannot delete DM IP White List in DM 5.13.9
<Description>
Cannot delete DM IP White List in DM 5.13.9
<Cause>
IP comparison with IP 0.0.0.0 (means ‘delete’) had a problem.
<Resolution>
IP comparison with IP 0.0.0.0 (means ‘delete’) is fixed.
7. [-/ALL/ALL] System reset when using ‘IP & Port’ option in DM 2.7.2’s NAT Check option
<Description>
After Setting DM 2.7.2’s NAT Check option to ‘IP & Port’, when the SIP extension tried to register, System reset.
<Cause>
Internal memory access error
<Resolution>
This internal memory access error is fixed.
8. [-/ALL/ALL] No Voice when SIP Station Group overflows into SIP Station Group.
<Description>
A call went to uncondition type’s SIP extension Group and overflowed into uncondition type’s SIP extension Group. When one SIP extension answered the call, there was no voice path
<Cause>
Media resource (MGI or MPS) control error
<Resolution>
This media resource control error is fixed.
9. [-/ALL/ALL] No Voice when Auto Call Recording on SIP Extension
<Description>
When talk with SIP extension set auto call recording, there was no voice path
<Cause>
Internal t-switch control error
<Resolution>
Internal t-switch control error is fixed.

[ Changes to improve SVM’s security]
1. [-/-/ALL] “Force Subscriber to change PSWD” will be set when it’s updated.
<Description>
To increase security, “Force Subscriber to change PSWD” option of DM 8.5 System Parameter is included in previous version. But it’s not enabled when it is upgraded.
<Cause>
It was not enabled not to affect current users using SVM system.
It’s enabled when the system is initialized.
<Resolution>
To increase security, it’s changed to be enabled when it’s upgraded from previous version.
2. [-/-/ALL] “Outcall Authorization” of EClass and MClass will be set to ‘No’ when it’s updated.
<Description>
To prevent toll fraud, “Outcall Authorization” of EClass and “Callback Authorization” of MClass is set to ‘No’ if it is initialized. But it’s not changed when it is upgraded.
<Cause>
Not to affect current subscribers using SVM system, the outcall authorization setting is not changed when it’s upgraded.
<Resolution>
To increase security, it will be set to ‘No’ when it’s updated.
<Consideration>
All outcall feature for example, ‘Follow me’, ‘Find me’, ‘Call back’, ‘Message alert’, ‘Direct call’ etc will be blocked if the outcall authorization is set to No.
But it only blocks when the subscriber tries to set the features. If it’s already set before it changes the setting, outcall feature will work. ‘Direct call’ will be blocked because you have to enter the phone number when you run it.
3. [-/-/ALL] “Edit stored telephone number” will be limited by “Outcall Authorization” of EClass.
<Description>
“Edit stored telephone number” was not limited by “Outcall Authorization”. It’s used by “Find me”.
If the subscriber is allowed to use “Find me” by an administrator(It’s not allowed in default settings), the subscriber can set long distance telephone number and SVM will dial that number although “Outcall Authorization” is set to No.
<Cause>
Design error
<Resolution>
“Edit stored telephone number” will be limited by “Outcall Authorization” of EClass.
4. [-/-/ALL] “Operator” extension cannot use “Direct call”.
<Description>
“Operator” extension(500) is included in default configurations.
It’s password is often not set, so it can be a security hole if the “No Messaging” EClass is allowed to make a outbound call.
<Cause>
“Operator” extension is quite same with the other extension, but no one changes the password.
<Resolution>
“Operator” extension is blocked to use “Direct call” regardless of “Outcall Authorization” of EClass.
5. [-/-/ALL] DTMF administrator is not allowed to access by pressing “#0000” when the admin password is not changed.
<Description>
DTMF administrator can create a subscriber, record a prompt and change the operating mode, but it’s easy to log on when the password is not changed.
<Cause>
The administrator can change admin password by DM 8.5 System Parameter, but it’s not force to change it.
<Resolution>
It will not allow to access as dtmf administrator by “#0000” before it changes the admin password from the default one.
<Consideration>
“VMADM” key made by MMC 722 is allowed to access although the admin password is not changed. But we strongly recommend to change the admin password.
6. [-/-/ALL] Remote caller cannot change his password.
<Description>
SVMi allows remote caller logs on his mailbox and uses it as if he is on his station. It can be a problem, when SVMi has an extension block that no one uses.
Somebody can log on it and he can make a outbound call if it’s allowed.
<Cause>
SVMi downloads the number plan and creates extensions and mailboxes.
In this process, many unused extensions and mailboxes are created.
Somebody can log on because it’s password is not changed.
<Resolution>
Remote caller is not allowed to change his password. It’s only allowed in station call.
This modification can solve above security problem if it’s used with “Force Subscriber to change PSWD”.
When a subscriber log on his mailbox at first, he should change the password, but illegal remote caller cannot change it and log on.
