EX90 two autonomous with the public IP address can make video calls among them self on the Internet or not?

Dear expert;

I am very new to VCS and TP Cisco.

We implement now presence Cisco TV with VCS - C, VCS-E TMS, TCS, MCUS and endpoints with Jabber in a single edit.

and in another configuration CUCM 10.5, UCCX 10.5 IM & P, Jabber with some 10 officers.

Now the question is in our building on the 2nd floor we have an EX90 and on the 5th floor an EX90 and on local network, we can make video calls using the IP address.

In the same way is it possible to make a video call between 2 devices EX90 (both have public IP) present in a location different in the same city on the Internet without the participation of VCS - C and VCS-E.

It's the client request :)

Yes, but leaving these systems outside in nature with public IP addresses, leaving you are vulnerable to a number of questions. See for example http://www.videonationsltd.co.uk/2014/11/h-323-cisco-spam-calls/

The offers above with H.323 calls, in addition to this, you will encounter similar problems using SIP where the systems will be analyzed by tools such as SIPVicious

  • [SOLVED] Help fixing 'file two systems with the same uuid were detected.

    I have a Setup ESXi embedded (installed on a USB key connected to the internal USB port) on a Dell T710 with few of the SAS drives.  I tried the upgrade to 4.0 - 294855 to 4.1 - 348481 by following the instructions here via:

    esxupdate--bundle=/vmfs/volumes/datastore_name/path/to/upgrade-from-esxi4.0-to-4.1-update01-348481.zip update

    Even if it is done correctly, when I restarted I got a purple screen with this message on this subject:

    The system has found a problem on your machine and cannot continue.

    Two systems with the same UUID files have been detected.  Make sure that you do not have two installations of ESXi.

    So, he tried to update one of the SAS drives internal versus inside USB key...?

    I studied this time before & found a threadwhere posted to help, but it wasn't enough to get me going.  Tonight, I found KB1035107 which details how to fix this, but I have a few concerns:

    • How can I identify the drive that has the invalid ESXi installation?
    • Better yet: How can I identify who / disc is the one with the ESXi installation I want to keep?
      • I know that I can use esxcfg-mpath-l., esxcfg-mpath-band esxcfg-scsidevs-l to collect the disk & LUN information.  But what happens if it wasn't a built-in installation?  If ESXi was installed on one of the SAS drives, how could I confirm which drive it actually installed on?
    • What is the worst that could happen with the performance he commands in the KB above?
      • Do I need to worry about migration whatever data is stored elsewhere there until I can get through this?

    Finally, and perhaps more important than these other issues:

    It is for me a way to specify which disk/drive/device to target when executing upgrades, more precisely from 4.0 to 4.1?

    How can I perform upgrades in the future without having to worry about this nonsense?  I don't want to have to disconnect from the LUN/warehouses of data whenever there is an upgrade (major or minor).


    Thank you very much.

    Yes and this message is a request is received (DND) 850 (16789 message id). If you read my last post, then I said-

    According to the newspapers about 20:40 (20:40) there is only a single transaction, which is the acknowledgement of the message (ID = 16789) sent to 2010.07.26 at 18:39:21:877

    As in the report you see two messages but there is no corresponding newspaper of the second message, so I suggest you approach a case with support. They would be better off to analyze your system and find the right problem.

  • Storage migration fails with the error: could not complete the network copy to path to the file

    Hello

    I have two hosts ESXi 5.5 with local storage and VMware vCenter device which manage them. Everything worked well until that time.

    Now when I try to make the host migration and storage, processing or power off the virtual machine, I get the error message:

    Could not complete the network for file /vmfs/volumes/.../path/to/file.vmdk copy

    The situation is the same when I try to deploy VM on ESXi-2 model that is on ESXi-1.

    All with the network configuration is correct. I have ping between the hosts on ESXi and ESXi and vCenter. No firewall hosts ESXi and vcenter. No physical firewall between hosts.

    The network latency is less than 1 ms. No packet loss.

    I read this VMware KB article: Storage migration fails with the error: could not complete network file copy and I tried solutions explained here, but the results are the same.

    You have ideas where the problem may be?

    Hello guys,.

    I finally found the problem.

    ESXi servers are configured with MTU 9000, but the switch where the hosts are connected was a bug documented with frames. I found the problem after finding this article http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1003734

    I run the command of ESXi-1:

    vmkping - d-s 8972 192.168.10.12 where 192.168.10.12 is the ip address of ESXi-2

    The result was:

    3 packets transmitted, 0 packets received, 100% packet loss

    as a workaround, I reduce the MTU to 1500, then I patched the problematic switch.
