deactivation of H.323 EX90 completely (you want to stop unsolicited calls)

I have a couple of EX90s located in a DMZ in a remote office. Is other than explicitly block the H.323 ports in the firewall possible to completely disable H.323 so that they are not unsolicited IP H.323 calls? The system's registered SIP with our fast track and I the direct value to the EX90 H.323.

Thank you!

It's always nice to leave both H.323 and SIP open and used the functionality where needed. While interoperability in general is OK, you may experience strange circumstance where it does work quite as expected.

(If you wish), you can paste the EX90 behind a NAT and use the features of the crossing of VCS so that it can register on SIP and H.323.  This will be more obscure the end point, but still allow it to be reachable via the VCS-E (you may need to test this with you firewall/NAT and reconfigure a few CODEC settings, but usually relatively simple). You can even configure authentication on H.323 as well, if necessary. I usually tie record Expressway to a public IP (membership area Sub rules) and also use a list of permissions, but have been playing with authentication for H.323 devices as well.

The dial plan is where you define what the calls are directed where the use of protocols.

Have a go and after return in a new thread if you encounter other problems.

See you soon

  • Mediathek photo: A way to keep the Photos on Photos.app when you want to remove them on the iPhone?

    I understand the concept of the Mediathek Photo.

    The goal is to keep the Photos on different places for example iPhone, iCloud and synchronized Macbook.

    Automatically.

    Because the volume of data on my iPhone is not very large, sometimes I have to delete the photos.

    Is it possible to prevent these pictures from beeing deleted on the Macbook?

    Or do I have to completely give up the automatic transfer of photos only?

    In my mind, I think of a kind of function of archive for Photos.app.

    A flag that prevents pictures archived the synchronization beeing part.

    Can you give me an opinion please?

    Thank you.

    Because the volume of data on my iPhone is not very large, sometimes I have to delete the photos.

    Is it possible to prevent these pictures from beeing deleted on the Macbook?

    Photo library of iCloud will synchronize the full library of Photos.   If you remove a photo from the library on a device, it will be removed from all libraries in snced on other devices.

    One way to synchronize on a selective basis would be to have more than one library of Photos on the MacBook. A library of synchronization iCloud Wavec with only the photos you want on your iPhone.  And a library with other photos that you don't want in iCloud.  See this help page on the use of several libraries: https://help.apple.com/photos/mac/1.0/?lang=en#/pht6d60b524

    Another approach would be to use "Optimize storage" on the iPhone.  Then the photos will be optimized smaller photos on the iPhone store and more pictures will be fit.

  • Which account you want to use to run this program?

    A week ago, just after installation of Microsoft Update, when I start my computer, a box came who said: run as.  Which account you want to use to run this program? [x] current [of user\Owner] protect my computer and data from unauthorized program activity. This option can prevent computer viruses from harming your computer or personal data, BUT selecting it might cause the program to function properly. Current use is already checked, and my options are to check I want is not protected, or cancel. I tried all the options, or just close the box. What is the devil? Why should I see it every time I start my computer? And, more importantly, why would I want to when, "selecting risk the program work correctly?" How can I get rid of this annoying box, since I already have Kaspersky as a guard dog? Thanks, Tess

    No, you are not condemned.

    To make the warning "diagnostic mode" Begone, re - run msconfig and select the radio to "Normal startup" button (cela re - automatically checks the Java update box, as well as all the other boxes you might get UN-ticked).

    The way you described your original message is a bit confusing.  Messages request 'which account you want to use' - what are the choices presented to you?

    Run as.  Which account you want to use to run this program? [x] current [of user\Owner]

    Is the account that you sign normally called "owner"?

    You have an x in the box in front of "Current user" - If the current user IS 'Owner' what does the other box reference?  It may be a better representation of the pop - up:

    Run as
    Which account you want to use to run this program?
    [] Current user / owner
    [] Protect my computer and data from unauthorized program activity. This option can prevent computer
    viruses from harming your computer or personal data, BUT selecting it can cause the program to
    work correctly.

    That is, we really give you a choice of the accounts, but only the current account or anything.

    When you go to control panel > user accounts, is the account that you are connected to a "Computer administrator" or "limited account"?

    You need to do some detective work more:

    • In the Startup tab, run msconfig and uncheck ALL items.  If the "RunAs" message does not come to the top, you know that one of these elements is the culprit.  Selectively, double-check items (you can do as a group to save time re-boot) and re-start until you determine what startup item causes the error.  Once you have identified the startup item that is causing the problem, post back with his name and I will try to help you determine what to do about it.
    • The "RunAs" message continues even with all uncontrolled startup items, you going to dig deeper.  Reset things to normal by selecting the option "Normal startup" button and follow the steps.  I'll look at other things that start when Windows starts and see if I can suggest the next steps.

    Hi Dale,

    Since you are not able to open a session in normal mode, log in in safe mode and perform a few steps that would help you solve the problem.

    Safe mode starts Windows with a limited set of files and drivers. Startup programs do not work in safe mode, and only the basic drivers needed to start Windows are installed.

    Perform the steps mentioned below and see if it helps.
    a: turn on your PC
    b: Press F8 repeatedly , then in Mode safe
    c:
    Logon as per normal
    (Note: administrator password is usually empty, but I hope you know your password)
    d: Authorize the Office to load completely (who answered "Yes" to continue mode without failure)
    (Note: this is just a long way to say go to Safe Mode)
    e: Click Start - run
    f:
    type exactly: rundll32.exe syssetup, SetupOobeBnk (then click OK)
    (Note: a single space after 'rundll32.exe' also the Oo are two letter o in "oobe"; capital and the comma are important)
    g: Wait a few seconds (although you won't see any change)
    h : Restart your PC normally (start - stop - restart - Ok)
    i: You will be able to return to the Normal Mode.

    Good day!

  • Why Microsoft did remove the ability for Windows Vista to install on herself from one location other than being inside the BONE you want to fix it?

    No Option to install repair - SAD

    Hello

    Why Microsoft removed the ability for Windows Vista to install on herself from one location other than being inside the BONE you want to repair.

    I recently had a problem where Vista Business 64-bit would only boot to a black screen with a mobile cursor - KSOD.   Who, in searching the Web I found is a fairly common problem with Vista.  I discovered that my only option was about to reinstall Vista CLEAN and all the other programs I had installed under it.  I can't believe that Microsoft released the 'repair installation option"similar to that of Windows XP, where you can hit the"R"key during installation and we left with nothing but the"System Restore"options and"Startup Repair ".  Neither of which has helped in my situation.  Since then, this was a dual system boot with XP Pro, then any restore point has been removed from the partition to Vista anytime, I started another recognized problem, by Microsoft, which Microsoft has made no significant effort to fix, in addition to recommending that you hide the partion Vista in XP - a whole of XP.  That beats a little the entire purpose of dual boot.

    As I tried to start in safe mode, it left me at the same point as a normal boot - black screen with a cursor.  I tried ctrl + alt + delete and nothing. Two Windows RE options did not help me.  This left me no option but to the completely reinstall Vista.   Why Microsoft did remove the ability for Windows Vista to install on herself from one location other than being inside the BONE you want to repair.. Please don't tell me that it is because Vista uses an image file instead of an installation as XP system.   I see no other reason for not allowing the upgrade of outside BONE in addition to Microsofts greed and paranoia that he can transform the operating system easier to install illegally.  I hope that some third party has actually changed the Vista installation routine to allow you to install Vista on itself, because as it is, it's really hard for me to even recommend Vista as the operating system or install any where else, if not the only recourse after loading OS, is to reinstall completely.

    Adobe, Autodesk, and almost all other software publishers... allow you to perform a "REPAIR" of their software installation, if something prevents you to load after installation.  Even MS Office has a routine repair.  Ms has an internal version of the Setup routine which allows outside the OS upgrade option that you want to "Upgrade" / repair? ".  If not, why?

    -Todd w.

    "Why Microsoft removed the ability for Windows Vista to install on herself from one location other than being inside the BONE you want to repair."

    «.. . After using XP's repair function, the operating system itself would become less stable and frankly not in a good state of repair. »

    As Todd, is the answer.

    "This response does not hold water as on one of my computers I've been running Windows XP for about four years now, after a repair install.

    Then, you were lucky.  Try to replace the system files on a computer that does not start even at a desk or safe mode usually will get a return to office, but will probably repeat the same problem in a few weeks.  Tech professional would only use this function to retrieve the data before a complete reinstallation.

    "I thought that this area was a place to really get answers instead of the ole same"answers of bs that are on all the other forums."

    It is a place that will try to help you fix your computer if you have problems.  It has technicians in computing, no decision-makers, developers or executives.  We will try to answer technical questions about problems you might have with Windows Vista.

    If you want to have input on the future of Microsoft operating systems, then help you beta-test and provide feedback to the developers.  Windows 7 and IE 8 are currently in beta.
