• MCU 4501 gatekeeper

  Hello

  Problem - gatekeeper integrated Cisco MCU 4501 cannot connect to a neighbour a keeper:

  

  In a nearby doorman it configured as a neighbour.

  Why would it be?

  In this case, I think you must turn on the logging feature H323/SIP on the MCU-> h323/SIP Journal newspapers, try to make a call and see what requests appear from the endpoint in the log that results.

• [Issue] it is possbile to use MCU 4501 on network 1:1 NAT?

  Hi, I have a very simple question.

  I'll put MCU 4501 model on a private network to connect to public IP codec devices.

  Without devices INCAPACITANTS, Turn, or VCS, it works standalone with H323 and its private IP address is set to 1:1 public IP address.

  In this position, is that it is possible another codec public IP can join the session of MCU 4501?

  In my view, would be well accepted, but given media cannot be accepted because the IP address in the payload would be signaling missmatching.

  No one knows about it? or can I use some free public STUN, ENABLE Server H323 Direct mode? or do it by myself?

  I have no senior engineer and I have to learn about it, everybody ask me when they stuck on the frame.

  This site is the last hope for me, and I'm sorry for imconvient read, it is not my mother tongue.

  Thank you.

  For H.323, IP address of the port media negotiate during the call setup is not using the IP header.

  If your compatible Firewall H.323 AGL, handful of firewall NAT IP and H.323 signal header conversion.

  However for MCU, you can consider the firewall on MCU option if you are looking for private/public double network connection.

• MCU 4501 problem! Help, please!

  Hello dear friends, my name is Svetoslav and I want to ask you the following question:

  I have reset the MCU because I did not had the admin name and password. Now there's a banner: "NO ACTIVE PRODUCT code activation required".

  My question is what I should do now, can be a problem to create a conference, because I'm trying to do a conference in menu-> settings-> SIP there is an inscription - > Registred, but when I put ID digital 1 for example and you try to create a conference on recording there failed to save... SIP registrar ID cannot save...

  I'm new at this and please don't laugh a lot may be the problem of the PRODUCT NOT ACTIVE banner? Thank you!

  Hello

  It's hapenning because the MCU has lost its license key. When the password reset, you must back up your license key before doing anything. See this link:

  http://www.Cisco.com/en/us/docs/Telepresence/infrastructure/articles/cisco_telepresence_resetting_password_restoring_factory_settings_kb_13.shtml

  To retrieve your license key, you can use the Cisco licensing page:

  1 - Go to https://tools.cisco.com/SWIFT/LicensingUI/Quickstart
  2 - Go to nonexistent Get > Tandberg license

  3 - Insert the serial number of the MCU and recover the license

  4 - Insert the license on MCU in the "Upgrade" page

  If you are not able to use this page, please contact Cisco GLO by sending an email to [email protected] / * /, so that Cisco will help you recover the licenses.

  I hope this helps.

• 2 MCU and VCS Expressway, routing problem

  Hi all

  We have a design with a group of control VCS (2 members), cluster VCS Expressway (2 members), and a couple of microcontrollers (registred H.323 on VCS control cluster with the same prefix: 90).

  Each highway has a public IP address and incoming calls from outside can only be routed to microcontrollers:

  [email protected]/ * / for MCU_1 and [email protected]/ * / for MCU_2 (we don't have external DNS resolution).

  I put a conversion into motorway of VCS to change [email protected]/ * / to [email protected] / * / and [email protected]/ * / to [email protected] / * /.

  The problem is when someone calls [email protected]/ * / sometimes (randomly) the call is routed to MCU_2 (instead of MCU_1) and if the appellant see the auto attendant.

  The occcurs even then of the appeal [email protected]/ * / (MCU_2), sometimes the call is routed to MCU_1.

  Any idea what can cause this device or a way to make it work well?

  Thanks for help.

  José

  I think still that separate prefix would work, but here are a few ideas:

  Are incoming calls which do not possibly using SIP that is being interoperability H323 or incoming calls all certainly the H323?

  If you want to keep pure H323, you could perhaps just have a search rule/turn on your VCS-E who changed [email protected] to an E164 e.g. 90... and had a search on your VCS - C rule that says 90... stop at the local area.

  I also noticed that you direct calls to [number]@MCU-IP - have you tried to direct all calls to [number]@VCS-C IP instead?  If the VCS is the holder of a registration for a number, it should be able to deliver accordingly.

• Questions of permanent conference MCU 4501

  Hi, I've created several permanent conferences on MCU.

  Permanent Conference sometimes appear as finished. Operators of swear that they have not finished their manually.

  Also, then I put the Conference, by changing its properties and 'permanent' checkbox control, he suddenly starts to all former in conference, even if there is NO preconfigured participant.

  This caused a lot of havoc and disruptions, by calling the BIG BOSSES and so on.

  Any suggestions?

  Software MCU:

  Version	4.3 (2.30)
  Variant	6.18 (2.30)

  Yes, it's what I expected to happen. When you add participants to a permanent conference using TMS, they are added as preconfigured participants, but TMS never deletes them. See bug CSCtr35038 for more information.

• MCU security problem? Automatic creation of conference.

  I encountered a problem which I have not noticed before.

  I was sent a MCU 4501 - v4.5 (1.45) - Note problem also exists in v4.4

  H.323 prefix: 89

  On the MCU I configured the creation of auto attendant and the disabled and access to ad hoc conferences with the digital ID: 8900

  When you make a H.323 call for 8900 (or 898900) you go to the auto attendant as expected.

  When you make a H.323 now call 89 MCU requires a security PIN and creates a new conference, even if no PIN is entered...

  Not exactly what I expect.

  To resolve this, you must create a new auto attendant and give him the digital id prefix: 89;

  When doing a call to 89 you find in the auto attendant and cannot enter an id existing conference.

  Further testing shows the same behavior that if you dial a number with the prefix, 89, e.g. 891234, in this case the MCU create again an ad-hoc conference which is not really what I want.

  How can I solve this problem?

  Rgds, Geert.

  Hi Geert-

  Can you tell us what you have calls of " ""entering the unknown conferences or auto attendants" " " value in the settings > conferences?

  Looks like you have set up to "Create new ad hoc conference", which will give you the results you see when someone made up in the MCU by using the prefix and anything after that is not either the Conference Officer or active auto.

  Try to change to 'Default auto Standard' and see what happens.

• VCS Cluster DNS problems

  Hello

  I have created a DNS SRV to configure in the FULL of the VCS Cluster domain name.

  The problem is when devices try to enroll in the VCS Cluster; I put in the endpoints, in Gatekeeper registration DNS or IP address of the DNS SRV but the always end points will never reach the cluster of VCS.

  I check the logs in DNS SRV and I don't see any request from devices.

  I think I need to create a virtual IP address with DNS with load balancing, I mean: IP/DNS (FQDN) for the Cluster with load and balance when devices trying to connect to the cluster's IP/DNS it transmits the request to an IP or host name of a host in the cluster.

  DNS cLuster

  23.1.0.201 (vcs.xxx)

  The peer of the cluster:

  23.1.0.32 (vcscontroltc.xxx) Master

  23.1.0.33 (vcscontrolvag.xxx) slave

  XXX--> field

  Is this right?

  Thanks in advance.

  Best regards.

  Hello

  then 23.1.0.201 is the IP address of your DNS server?

  How you need to configure is:

  FULL of the cluster domain name: vcscluster.domain.local

  VCS counterpart A: vcscontroltc.domain.local

  VCS counterpart B: vcscontrolvag.domain.local

  With the above assumptions, that's what you create in DNS:

  -For the FULL domain name cluster, create two A records for vcscluster.domain.local one pointing to 23.1.0.32 and the other pointing to 23.1.0.33. With that, I recommend that you enable alternate on your DNS server.

  -For each peer, create a record, so vcscontroltc.domain.local points to the points 23.1.0.32 and vcscontrolvag.domain.local to 23.0.1.33.

  -Create SRV H323 and SIP records for vcscluster.domain.local. With that, I recommend that you create two SRV records for each service, pointing A Exchange and showing a B counterpart, with a weight and priority. For example:

  _sips._tcp.vcscluster.domain.local-> vcscontroltc.domain.local, priority 1, weight 50

  _sips._tcp.vcscluster.domain.local-> vcscontrolvag.domain.local, priority 1, weight 50

  If you follow the advice above, you should be able to configure all of your interior SIP and H323 endpoints with a h.323 gatekeeper address/SIP proxy address, of vcscluster.domain.local and endpoints must enroll in one of the peers, regardless of whether endpoints supports DNS SRV.

  If the domain that you use is public, you also want to add the SRV records for that domain name. These SRV records must point to your VCS Expressway, to ensure that incoming calls from URI function as it should. For example:

  _sips._tcp.domain.local-> vcse.domain.local, priority 1, weight 100

  If you have several VCS-E you can adjust the SRV records accordingly.

  Hope this helps,

• TCS Auto Dial with MCU

  I have 4 points of C20 endpoint that will call in a standing conference that is configured on the MCU 4501.  The customer has also a TCS as we would like to record calls with.

  If I place the TCS to call the microcontroller on a permanent conference it never ends.  All my clients can end it calls but how am I supposed to get the TCS to put an end to his call?

  For now, I tried to settign the Permanent Conference call TCS, but then the TCS records when nothing happens and never ends his appeal.

  Is there a better way to implement?  I don't want to use Adhoc calls and it must be easy for the customer.

  Most of the time the CHT requires a VCS.

  You can try to do only one, the "President" of your Conference permanent.

  Set the Conference to terminate when only participants are present.

  Configure the alias for the TCS as an endpoint.

  Configure a specific permanent conference to call for the specific TCS as a preconfigured participant alias.

  Join the call of the President.

  Join the call as the participant.

  MCU call TCS.

  Chair leaves the meeting.

  Meeting move out.

  While I don't have this Setup myself, we are essentially doing the same thing with an outgoing PSTN, so I don't see why it would be different.

  The TCS is registered to the GA on the MCU as well?

  Why no VCS?

• Capacity issue series MCU 4500

  Hello

  I need to ask for a solution for a video conference 15 of the participant.  The meeting is between the main site of customers (1 standalone codec c40) and 14 others on remote sites.  Given that the other sites have no infrastructure my plan was mainly using functionality MCU Conferenceme to invite all other participants.

  I was also counting the c40 register with access to the builtin H323 MCU controller.  Which would be ok?

  1. based on the data sheets, it seems that Conferenceme is limited to 12.  Is this correct?  15 party conference would not be reached here.  All the suggestions here

  2. I could involve some clients Movi.  Now, I have to add a starter of VCS originally C40 + MCU 4501

  Also for the 4501 with 6 to 12 HD Port Option (SD 12 to 24 Ports). What is once the Conference Expands to 12, it will be downrated from HD to SD for all participants?

  Finally what bandwidth up/down would you recommend for this conference say 15 part to the quality of the SD?

  My apologies for the bundle.

  HI Ricardo,

  Since you need 15 participants I would say ither to buy 6-12 HD functionality, in order to double the capacity or

  go for a physical upgrade to a MCU 4510 (with 20 dedicated ports of capacity for video / audio 20 / 20 content)

  The SD / HD mode is a global setting, you can configure the appliance to use only SD or ports only HD, you can not mix (for ex you can not use 3 HD and SD 6-port, you can either use 6 HD or SD 12 (or double the capacity with upgrade key))

  The Porter built in of the MCU can handle a maximum 25 points of endpoint recorded, but it has very basic functionality, I highly recommend using a VCS like dedicated GK and record the MCUS and endpoints of the VCS

  Regarding bandwidth, I'd go for at least 768 Kbps (you can use 512 however more body weight, best quality)

  I hope this helps

• Check MCU

  Hello

  I configured a MCU 4501 and i´d as save some 55 aircraft ex90, c60 and profile via the SIP protocol, I can do? or these devices can only be registered by h323.

  Thanks in advance.

  Hello. These devices can register SIP and H323 if you have a device like VCS. If you register for mcu gk, tthat only supports H323. It would be better to have VCS have SIP TO SIP and H323 H323 and VCS calls also provides interoperability of both needed. I hope this helps.

• Problem with Edge95 MXP and H.264 DualVideo (H.239)

  Hi experts,

  We try to make a MXP Edge95 serve H.264 codec for presentation to Radvision/Scopia MCU using H.323 signalling Protocol and H.239 as standard presentation. But it seems to only use as H.263 codec.

  When the presentation is started from endpoint Edge95 MXP, only main video appears on remote side (except H.263 is used for presentation)

  Presentation at the start of the side remote, only main video appears on the endpoint Edge95 MXP (except H.263 is used for presentation)

  -H.239 is obviously active, all video codecs are enabled (H.263 and H.264)

  -Video quality is set to Motion for main Cam and sharpness for PC

  See attached Wireshark packet captures.

  Hello

  This is an expected behavior for MXP. He always uses for presentation h263 / duo video.

• Streaming in MCU

  Hello world

  I know that in MCU (4501 for example) I am able to run a Conference and a user can open its browser and view and listen to a conference, but what happens if more user wants to do the same thing? Where can I find a document on the configuration of this feature? I MCU administrator red guide, but it is not this information.

  Thanks in advance.

  Hi Juan,

  This is the best document in my opinion all streamign on Cisco MCU. But you can find more information on how to configure streaming in the guide of the administrator, starting at page 195:

  http://www.Cisco.com/en/us/docs/Telepresence/infrastructure/MCU/admin_guide/Cisco_TelePresence_MCU_4-4_Product_administration_guide.PDF

  Starting on page 15, you can find information on how to see the Conference using the streaming:

  http://www.Cisco.com/en/us/docs/Telepresence/infrastructure/MCU/admin_guide/Cisco_TelePresence_MCU_4-4_Product_administration_guide.PDF

  Another guide explains how to use the mode full-screen streaming for quick time player:
