Update Tandberg E20 TE2.1.0 TE4.1.0. Encrypt or not encrypt?

Hello

I am CCNP, but a beginner VOIP, just took a new job.  That is why the first VOIP LAN.

I upgraded my LAN using switches of WS-C3560X.  I'm upgrading 60 Tandberg E20 video phones from TE2.1.0 to TE4.1.0 because of the E20 not finding the vlan voice.

I use Avaya S8800 Server CM 5.2.1 with Avaya phones model 9640D01A-1009 and model Tandberg E20 video phones.

I am trying to decide which software to use; with encryption or no encryption.

Software Cisco E20

S52100te4_1_1.pkg AES encryption

No encryption s52101tenc4_1_1.pkg

Q1.  What's being encryption?  Voice traffic is the obvious answer to this, no?

Q2.  This device is at the other end of the encryption?  CM or telephone

Q3.  Since the appeal will go outside my Avaya CM (ie. call to the outside world), encryption important?

Thank you for your time and effort.

Scott

Hello.

S52100te4_1_1.pkg AES encryption for the countries where the AES encryption are allowed.

No s52101tenc4_1_1.pkg encryption is the countries where VOIP encryption is not allowed by law.

You have only one key to unlock for one of them, so there is really no other choice.

You can choose to disable encryption on the TE4 version (so it will have the same function as the TENC4), but you are not able to activate encryption on the TENC4.

TE4 encryption is disabled by default, in any case, if the different software versions are here just for the legal question.

Q1: Call for installation and the RTP stream can be configured to be encrypted on TE4.

Q2: Endpoint or device interop

Q3: It depends if your Avaya CM supports encryption or not.

Thank you

Marius

  • Update Tandberg E20 TE2.1.0 TE4.1.1. Phone is set to both data & Voice VLAN

    I've updated a Tandberg E20 TE2.1.0 to TE4.1.1 (without encryption) phone is now appear in the two VLANS data & voice/video.

    It seems that the voice traffic and data is properly managed, due to the fact that when I STOP the audio/video/VLAN no appeal that can be sent or received.

    Q: do I need to worry about why the phone of Tandberg is now appear in the two VLANS data & voice/video?

    Thank you, Scott

    Hello

    I think what happens is that when the device is initializing, DHCP tries to get the IP address to the VLAN 100 native. After that CDP discovers there is a voice VLAN, endpoint application address DHCP VLAN 11. So you see twice MAC:

    #sh table of mac addresses

    Mac address table

    -------------------------------------------

    VLAN Mac Address Type Ports

    11 0050.6004.2451 DYNAMICS Gi0/2 / / Tandberg E20

    100 0050.6004.2451 DYNAMICS Gi0/2

    If you open the MAC address table, the entry for 100 will disappear [I hope].

    The other entrance to the connected PC is normal.

    #sh table of mac addresses

    Mac address table

    -------------------------------------------

    VLAN Mac Address Type Ports

    100 1803.73e3.083c DYNAMICS Gi0/2 / / workstation connected to E20

    We have a DDT where we would not obtain a correct address in the case of CDP Auto: CSCtx84402.

    Should be fixed in the TC6 release.

    A lot of people is affected by this problem, and Apple has worked on the issue.  Some found the following steps useful for this issue:

    Go to iCloud.com and select settings once you are connected.  Click on your device listed there and remove them from the account (not typing not erase or lost mode).  Restart your device and must ignore this lock of Activation screen because you actually disabled the lock by removing the device for iCloud.com

    I would say "try and do a restore as new iPhone" like everyone else but I'm having a similar problem and nothing works! I've restored all the possible ways and nothing. I got my screen replaced and I still have the same home button but my phone updated with error 53 (makes the phone unusable) but the camera did work before the update. and Apple has released iOS 9.1.2 (13D 20) to correct the error 53 (mainly for other reasons) but when I go to use the camera, it is only black! If someone could help 'discovered' and I would be great!

    You are using a newer version of El Capitan that the updater contains and so cannot install it.

    I ordered the Dell XP disc and did the re-install. It works fine now. The Dell technical support had me do some updates on the web as well. I have not had problems since. What happened with the automatic updates completely wiped out my operating system. At least I don't have to buy a new computer.

    If nothing else works, try reinstalling your operating system. It worked for me.

  • Vista SP1 does not update problems and System Restore returns a message "system restore was not entirely successful. File system and the setting of your computer has not changed"with the error code (0x80071AA7)

    0rignal title: Vista SP1 didn't update problem

    So, recently, I was on my computer of gf and noticed she had some updates, it could use his computer which included the SP1 update.  So I went through the process trying to update his computer and he has been a disaster and have had many problems and seems to have tried everything.  It has a Dell inspiron 1525 and has no CD and no key for its program of Vista.  I burned a Vista recovery disk and tried troubleshooting by using that, but have not had much luck.  When I use the Startup Repair tool there is no nothing.  So I tried to use the restore of the system with the Description of "install: Windows Vista Service Pack 1.  He had a restore point saved just before I tried to update to SP1.  Whenever I chose this method, it's but the whole process then in the end it says:

    "System restore was not entirely successful.  File system and the setting of your computer have not changed. "

    then he begins to list the details with the error code (0x80071AA7) and then gives me the option to close or 'Run System Restore"once again that is an endless loop, because I just end up with the same error each time.  If anyone has had this problem and bring myself through it.  I don't want to reinstall windows because it seems simply ridiculous and plus that she a lot of pictures on his computer and I want to get rid of those.

    Hello
     
    Follow the steps and check if the problem persists.
     
    Step 1:
     
    I suspect that your security program may be responsible for this. I would suggest you temporarily disable all security software and try the system restore.

    http://Windows.Microsoft.com/en-us/Windows-Vista/disable-antivirus-software
     
    Note : Antivirus software can help protect your computer against viruses and other security threats.  In most cases, you should not disable your antivirus software. If you need to disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network, while your antivirus software is disabled, your computer is vulnerable to attacks.
     
    Step 2:
     
    As for installing updates is concerned, I you should install them after you put your computer in aclean boot State. There could be a third-party software in conflict with updates. Clean boot helps eliminate these conflicts.
     
    Note: Restart your machine as usual by following step 7.
