Audio&video conference network deployment

HI guys. I am new in conferencing so apologies if u guys think  my question is stupid . There is voice and data network and we need to install Biamp conference system which need connection to voice net for voice traffic and to data network for video traffic  . What is the good practice :
a) to create separate vlan for conference on the core switch which will do routing for both data and voice traffic? 
OR
b) use separate physical connections to voice vlan and data vlan (that mean need ip from data and ip from voice to be configured on conference system) ?
thank you .

Hi Bekzod,
Since the same node is processing both audio and data portion of the conference, you will have only one IP for the server. Hence, what we've seen is all the conferencing is kept on the same VLAN. You can later on regulate the priority of packets on the network with QoS.
I hope this helps.

  • Audio Video Conference application with JMF

    hi there!
    I am developing an "Audio Video Conference application". so far I've been able to develop an applicaiton which opens an RTP Player on the client side, now my purpose is to enhance the functionality of RTP player by adding various functions like "Quit", "Pause" etc. I am looking for more options for enhancing the functionality of the RTP player in order to make it more user friendly for example I've been able to find the method for quiting from the player which is "KillThePlayer()" it is found in the class "PlayerWindow".
    java.lang.Object
    |
    --java.awt.Component
    |
    --java.awt.Container
    |
    --java.awt.Window
    |
    --java.awt.Frame
    |
    --com.sun.media.ui.PlayerWindow
    |
    --RTPPlayerWindow
    Please suggest me some of the classes and methods where I can find the method(s) for "Pausing the player" by which the player stops recieveing data and when un-paused it again starts recieveing, and also suggest me more functions to add to the RTP player so as to make it more user friendly.

    hi!
    thanx, I appreciate your interest! i know i am hitting the wrong forum but i have also posted my query in the JMF forum, i waited for long but unfortunately there was no reply posted to my request, so i just thought why not to try on some other relevant forums.
    if there is any sort of refernce available to my topic please help me.
    thanx for your help,
    bbye!

  • Using IOS Guaranteed Audio Video Conf. Bridge

    Using UCM 8.6 and IOS 15.1, I've set up a Conference bridge of type "
    Cisco IOS Guaranteed Audio Video Conference Bridge".  It is registered and everything looks good.  Will UCM use this same resource for standard, audio-only conferences?  Or do I need to also set up a "Cisco IOS Enhanced Conference Bridge"?
    I've read through the SRND, but can't seem to find a good resource for configuring these features.

    Hi,
    Error 7 means that something other than iChat cut the connection, normally during the connection process.
    Check your modem or router for DoS (Denial of Service) Or SPI (Stateful Packet Inspection) as both are somewhat threshold based and could be effected if you have had a recent increase in internet speed.
    Turn them off if you have them.

  • Why is there no audio during the video conference?

    I am using iChat AV on my Macbook Pro and my friend is using AIM 6. We are trying to video conference and we can see each other, but there is no audio. What is the problem and how do I fix it?

    Just click the Mute button for just a second, then unmute it by clicking it again. This causes iChat to reassess the connection and that might do the trick.
    You need iChat version 3.1.8 (445), AIM 6.1 should be on the PC and your friend needs a built in microphone in this webcam.

  • Tandberg C40 Video Conference not established just Audio Call

    Hi,
    I'm running CUCM 9.1 with Tandberg C40 TC5.1.11 + MCU3515. When a Video Call has been established it works like a charm but when a 3erd Video Phone is added the video conference is established but the tandberg display a "Audio Call" message. The video conference is established running a MCU3515.
    What's wrong? Do I need a additional license? This is the license installed:
    Valid release key:
    Yes
    Installed options:
    NaturalPresenter, PremiumResolution, DualDisplay
    Thanks in advance

    Hello Leo -
    You're issue to me is hard to follow and understand, if you could let us know more about what you're trying to do, it would help, be as descriptive as possible if you can.
    At what point are you seeing the "audio call" message on the C40?  Typically you'll see that when the C40 already has one video call connected, anything that tries to connect after that will take the remaining audio only port, as the C40 can support 1 video call and 1 audio only call.

  • Maximum Video Conference Reached, retry call as audio

    Dear All,
    i have ip phone 8945 series and router. i configure router as video conference bridge. i set maximum participant for 4 persons. i also configure separate audio conference bridge on the same router.
    when the max video conf participant reached (4 persons), is it automatically add the new participant as audio only?
    because in my customer, i can't add another participant.
    Please advice.
    Thank you,
    Anju

    Adding to what jaime said, "Maximum Participants" define maximum number of participants per conference above which no more users can join the same conference.
    Although  you can have audio participants join the the video conference within the limit of maximum number of participants in a single conference.

  • How can I tell that AutoQOS config is adequate on a video conference switch

    I have a Tandberg video conference bridge and gateway connected to a 3750 switch. The audio is marked EF and the video CS3. I configured AutoQos on the switch and trust DSCP on the ports. When we reach a large video conference of 25 or more attendies, we begin to have problems. The Tandberg starts to ratchet some of the video streams down, some to below 180kps, and the conference quality begins to suffer.
    The only change to the default AutoQOS config I've made is changing the "mls qos trust dscp" on the uplinks, adding a QOS policy on the Tandberg ports to mark the video with CS3 and trust the audio DSCP (Tandberg had a bug that didn't mark the video packets) and adding
    queue-set 2
    priority-queue out
    to the uplinks.
    Will the default AutoQOS queue/buffer/SRR share and shape commands be adequate for 25 to 30 simultaneous video streams? We allow about 500k per stream.
    I read through the 3750 QOS guide, but am a bit confused with the explanations of the queuing and SRR workings. I know that CS3 is mapped to COS-3, but don't know which queue it goes in and whether or not it gets shaped/disgarded when too much video is present.
    Once I am sure that the 3750 QOS is working OK, and not causing problems with our large conference calls, then I'll expand my troubleshooting to the rest of the network.
    I've attached a text file with the 3750 config, and 'show mls qos int statistics' that show the packets are being marked.

    I mistyped in my first post. I do indeed mark the video as AF41 (Cos4). It is the call control that I mark CS3 with the policy map to get around the old Tandberg bug that doesn't mark the call control.
    So do you think the queue 3, where Cos4 goes to, is big enough to handle 30 video streams of 480k? If my calculation is correct that would be 14.4mbps of video on a 100mbps port.
    With this config.....
    srr-queue bandwidth share 10 10 60 20
    srr-queue bandwidth shape 10 0 0 0
    ...is it telling me that queues 1 & 2 get 10% bw, queue 3 gets 60% and queue 4 gets 20% bw and is shared? If that is correct than 60% is more than enough for 14.4mbps of video.
    What happens if too much video overruns the queue?

  • Audio/Video Chat not working

    Okay, this is the question to end all questions. The one that stumps everyone, but I would really like an answer.
    Okay, so here is the problem. On iChat, I am unable to do Audio and video chats. Whether it be from a .Mac account or from an AIM account, it doesn't work.
    Here is what I have done to narrow down the possibilities a lot. I am running the newest iChat.
    1. I have tried without a router (Even though it is an Apple Router)
    2. I have tried without software firewalls in addition to router.
    3. I have done hardwired and WiFi.
    4. I recently noticed this when I switched ISPs. It says insufficient bandwidth despite the fact that my new ISP is 2x faster.
    5. I have tried multiple machines and cameras.
    6. Skype video and audio chat work fine.
    7. I have changed the ports so I know that the ports aren't being blocked.
    8. I have contacted my ISP and they said that iChat should work fine.
    9. I have deleted the .plist file so that I can restore to factory defaults.
    10. I have created guest account to use iChat to lower the chance of conflicting software.
    11. I have set Quicktime's streaming limit to "no limit" or what ever was the highest.
    I probably have tried a million other things, but under the above circumstances, it still doesn't work.
    Here is the report I get when trying to connect on a MacBook over WiFI. I can also get the PowerMac G5 one if necessary.

    If anyone has any suggestions, I would greatly appreciate it as I have been working on this for a long time.
    Or, if anyone knows of another chat program that can do video chat with iChat for the Mac, as Adium will not do it.

    Hi stevesol,
    It is not so much a problem with iChat as a problem with the vast options there are in Networking.
    In your case your Audio connection points to the fact that the ports needed for iChat are open. Video and Audio chats use the same ports.
    He may have a good connection speed but the the other people on his Network at his end will divide that up into Bandwidth.
    Think of it like a Highway with three lanes. When it is empty you can go as fast as you want. When there are more people it all slows down, sometimes to a crawl.
    Audio chats will work at Dial-up speeds. (upto about 50kbps)
    Video chats need 100kbps minimum.
    Now in some Universities/Colleges in the States as Students effectively pay to go, they get regarded as customers and if the Internet access is part of the service then the IT dept sometimes allocates an separate IP address giving the student all the bandwidth he wants.
    There can be issues with the number or routers on a large campus and how they keep all the subnets separate. This is normally done using NAT (Network Address Translation)
    This makes sure data for one computer is passed through each device correctly.
    Now the router and modem manufacturers don't all do NAT the same way so sometimes you get devices that "don't seem to Like each other"
    Using UPnP (Universal Plug and Play) can help get around this.
    If your son is in a shared room with a router for a room-mate then suing this may help.
    If you can use UPnP then that may help.
    I would guess this is something that is effecting your wife's contact.
    NAT needs ports to be opened in your router.
    Doing it with Port Forwarding or DMZ opens the ports to just one IP (Computer) on your home network which might also explain why your wife can not Chat if she is on the same LAN/network you are.
    Apple have decided that iChat is an VoIP application.
    VoIP has international Standards about how connections are made and one which ports.
    IT uses a internet Protocol called SIP (Session Initiation Protocol) that uses set ports (5060-5063). It uses one of these to make the call and uses the others as fall backs.
    Now bigger firms and campuses can be using VoIP for their phone service.
    Because some ISPs are or were telcom companies these sometime block the SIP ports to "make" people pay extra for the service (you can call anywhere in the world within the cost of your internet service).
    They will normally unblock this if you day that have started to block an application you were using.
    As you can see the problems can begin to overlap and cause issues that can be difficult to solve with a Once Only Fix.
    Can you tell us if you and your wife are on the same home network ?
    If so how many routers and modems do you have ?
    What makes and models are they ?
    What have you done so far to set them up for multiple computer to use the iChat ports ? (or otherwise)
    Of course this is all before we get into Universities doing things at their end for "security" or limiting Bandwidth to students to protect their network from potential outages

  • IChat video conference question?

    I have a couple of and maybe some dumb questions.
    I manage a small office with 3 Dell desktop windows XP Pro computers and 2 Macs (1-iMac 1000GHz & 1-Powerbook G4 1000GHz, both 10.4.8) and one Savin Office scanner/copy machine. The one Windows XP computer works as the server for the Savin copier. All are assigned static IP addresses. I'm presently running a Linksys wireless router WRT54G. We have several other seperate locations associated with the business where we would like to be able to video conference with iChat.
    I use to be able to iChat (video & audio) with the office computers for about a year and a half from my office but after changing the Linksys router from an older non-wireless version to the newer wireless version WRT-54G vers. 5, I can no longer Video or Audio iChat with the office on either of the 2 Macs listed above (text chating is no problem). The 2 office computers can no longer Video or Audio iChat with any other locations any where (but they can within the office, machine to machine). After exhaustive research, I'm convinced it is the Router.
    I was thinking of getting the new Airport Extreme base station with N, that Apple is now advertising, to see if this works. My first question is, will it work with the Savin Office copier/scanner like the Linksys does? Is it any different in setting up than say the Linksys?
    Is this more of a HOME piece of equipment or can I really use it in an office setting that is truely cross platform. (all computers file share with each other, particularly with the one XP machine that is the server for the Savin scanner.)
    Will I have any problems at all with iChat.
    I know there are a lot of questions but I really don't want to spend the money and disrupt the office if there is any anticipation of problems.
    The business is a Day Care Center with 9 locations so the Video & Audio chat is important to the kids and the office personnel.
    If this will work flawlessly, I would go ahead and replace the 10 routers for the 10 different centers we have, so everyone can Video & Audio iChat.
    Thanks for your help.
    Jim

    I use to be able to iChat (video & audio) with the office computers for about a year and a half from my office but after changing the Linksys router from an older non-wireless version to the newer wireless version WRT-54G vers. 5, I can no longer Video or Audio iChat with the office on either of the 2 Macs listed above (text chating is no problem). The 2 office computers can no longer Video or Audio iChat with any other locations any where (but they can within the office, machine to machine). After exhaustive research, I'm convinced it is the Router.
    Might it be that you just don't have the proper ports opened on the Linksys router to allow for both the audio & video portions of iChat? The following site is a great tool in setting up ports for specific routers, including your Linksys: http://portforward.com/default.htm
    I was thinking of getting the new Airport Extreme base station with N, that Apple is now advertising, to see if this works. My first question is, will it work with the Savin Office copier/scanner like the Linksys does? Is it any different in setting up than say the Linksys?
    I am assuming that your Savin copier is Ethernet-enabled. Since the new AirPort Extreme Base Station (AEBS) provides three Ethernet LAN ports, it should function similiarly to the Linksys to provide network access to the Savin. Since it a different device, there will be differences on setup. For example, the previous AirPort base station relied on the AirPort utilities for setup...and not a web-based one like the Linksys do. This is expected to be the same for the new model.
    Is this more of a HOME piece of equipment or can I really use it in an office setting that is truely cross platform. (all computers file share with each other, particularly with the one XP machine that is the server for the Savin scanner.)
    I would treat the AEBS no different than your current Linksys. Would you consider the Linksys a "HOME" piece of equipment? The AEBS should fit in quite well in a business environment as it does in a home one.
    Will I have any problems at all with iChat.
    As long as you have the proper ports opened on BOTH your hardware AND software firewalls, should shoudn't have any problems with iChat.

  • IChat audio/video not working in a particular scenario.

    Three differnt people with 3 different setups trying to do an audio chat:
    John: MacBook(2.0Ghz, Leopard), connected via AirportExpress, using an AIM account
    Anne: MacBook(2.4Ghz, Snow Leopard), connected via a 3G USB Modem, using a .Mac account
    Mark: iMac(2.0 Ghz C2D, Tiger), connected via AirportExtreme, using an AIM account
    John can voice and video chat with both Anne and Mark, no problem. But Anne and Mark constantly get the Error-8. (But strangely Anne and Mark can share files via iChat just fine.)
    If it was a firewall issue, wouldn't one of the three be excluded from any voice/video chat completely ? Im starting to wonder if it's the NAT/PMP issue as well, cause it doesn't seem to be an issue when connecting to the other person.
    I have scoured the web looking for a solution but to no avail.
    This is a snippet from the error log:
    Video Conference Error Report:

    Hi,
    Re 1)
    iChat makes a Connection that is Peer-to-Peer when doing Audio Only and Video chats.
    To do this it uses a method of going through NAT Devices (Network Address Translation)
    NAT Is not a standard. It is a vague description of things that happen in most domestic routers to share one IP between many computers and other devices.
    There are about 4 main ways of doing it See Here
    Realistically iChat can be Fussy as to how NAT is done. (Some methods don't seem to "Play Nicely" together)
    So you can get what looks like intermittent symptoms.
    Re 2)
    I am on a Leopard booted computer and my AIRPORT UTILITY is version 5.5.1
    I don't have an Airport Base Station so posting a pic is useless at this point.
    The older firmware I am thing of popped up a very small Window asking for the Password before giving you the main window.
    The version I have lists the different Base Station it can find down the left with a manual Configure Button and a first time set up button on the right (I forget the name).
    It sounds like he has something closer to my version.
    The Port Mapping Protocol may be "Greyed Out" if the Device is NOT "Sharing an IP" on the main Internet icon/pane. (On the current version I believe the NAT tab disappears if this is the case).
    Re the Zyxel.
    Not particularly iChat Friendly as a range.
    There is something about them logging in to AIM on Port 5190 on the TCP Protocol and iChat send files on port 5190 on UDP that these modems don't like (Dual use of the same port)
    This may be related to Port Forwarding.
    With setting up Port Forwarding you point one port to one IP (Computer) (multiple ports one at a time for iChat)
    This means that other computers cannot then use those ports (ports Cannot Be Forwarded Twice).
    Not all devices specify Protocols to do this but the Zyxels do seem have an issue with and for some reason this crosses over into A/V Chats.
    SOLUTION
    In iChat go to the Preferences > Accounts > Server Settings tab when Logged out.
    Change th Login port from 5190 to 443
    This port is memorable as it is below the 1024 threshold in most domestic devices (all ports below this are Open to everyone) and is used by Web Browser for Secure sites (such as Banks and the Sign-in here to post).
    It is also used by some mail servers.
    The Modem most likely routes.
    This means two things.
    1) the Airport Base Station should NOT - Set it to Bridge (Off) Mode in the drop down at the bottom of the Internet pane (Port Mapping will not be needed then either).
    2) the ports need to be allowed in the Modem.
    See this page
    This is the instructions to access a P660R-HW T1v2 I am not sure what the difference the HW means
    Do the pics look like his set up pages ?
    Most likely he will have to Look for UPnP - Try the Advanced menu item.
    He will not need the Port Forwarding if he Enables UPnP.
    He may have set up pages that look more like these pics EQ 660 R
    Here you can plainly see UPnP in the middle menu 9At the bottom)
    Summary
    Change port for Login in iChat
    Set Base Station to Not Route.
    Enable UPnP in Zyxel modem. (DO NOT use Port Forwarding despite the Links (they are just for the Pics and Instruction on how to access the device).
    If he cannot find UPnP come back to us.
    He may have to set Port Forwarding if it is only one computer.
    As he is on Tiger he cannot do iChat Screen Sharing so that will not be so much of an issue.

  • No audio/video/screen-sharing problem in iChat 4.0

    I've been using iChat for years (since its original release) and since upgrading to 10.5 I can no longer audio or video chat; and the new screen-sharing option doesn't work either.
    I connect to the net through an AirPort wireless network, which is connected to an ADSL Nation X-Modem/Router. I have a 2Mbps connection. As far as I know all the required ports are open on the router. My friend has the same ISP as me (Force9) and has made sure he has the same ports open on his router too.
    I've adjusted my iChat settings to port 443 with no SSL and a Bandwidth limit of 500 Kbps in iChat; and QuickTime settings to 1.5 Mbps in System Preferences. I've read other discussions on this forum suggesting these options.
    However, nothing seems to work. I can't even get audio and video to work across Bonjour on my home network any more. I'd be grateful for any help anyone can offer.

    Hi,
    Technically it should not matter if you are using AIM or @Mac names.
    However you have solved that bit.
    The Screen Sharing part uses three ports.
    Two randomly picked ports for the Screen Sharing and the same A/V port for the Audio component. As the Airport is normally set to Share An IP and does NAT on the fly so to speak this also should not be a problem
    The ADSLNAtion site is a bit behind on it's Airport page
    http://www.adslnation.com/support/knowledgebase/ht007.php as it shows the older Firmware pics.
    I found the new page
    http://www.adslnation.com/knowledgebase/xmodem+airport-11n.php
    This says that the DNS server info in the Airport needs to be removed.
    It is not clear if this is a variation for the X-Modem M3
    Very few of the posts here http://forum.adslnation.com/viewforum.php?f=3 are after Leopard came out and nothing appears to be about iChat.
    So it would somewhat depend if the Airport is Sharing and IP or is Static to the computer and Port Mapping used.

    Hi cesar,
    Welcome to the Apple Discussions
    This bit is the important bit
    Chat ended with error -8
    Video Conference Error Report:
    Video Conference Support Report:
    Video Conference User Report:
    Binary Images Description for "iChat":
    It list no information about making contact at all.
    iChat sends and receives the invites on port 5678
    If your Buddy saw this and accepted then this port is open.
    The process then moves to port 5060 and ichat contacts an SIP server called SNATMAP
    This bit is the bit missing in your log.
    Either of these things is happening
    1) the port is not open in your Mac Firewall or the modem and any router you have.
    2) you have a piece of VoIP (phones over Internet) equipment in the wrong place for ichat in your home network.
    3) Your ISP offers a VoIP service and is blocking the SIP ports to get extra money
    4) You have a modem that is SIP aware. Thomson Alcatels are most likely but also some Drayteks and the UK BT Home Hub

  • Video conference gets corrupted about 2 minutes in.  iChat 3 and 4 both.

    I've been experiencing this with my mom and we can't figure out what the trick is.
    She can video conference with my sister for a long time and never run into this issue.
    I can video conference with anyone else for a long time and never run into this issue.
    It only happens between my mom and I when we talk. After about a minute or two her video goes bad and it's hard to continue talking. She says my video is fine, and I can hear her, though the audio cuts in and out too.
    I took a screen shot of what it looks like and put it on my site here:

    Does anyone have an idea of what's happening. She has a 2 year old iBook (I think 1.07Ghz G4). I'm using both a MacBook Pro Core 2 Duo (built in iSight) and a Quad-Core G5 (iSight attached on top) - the problem happens with both machines.
    We just upgraded her router to the newest Airport basestation. She's got a super quick cable connection.
    I'm using a Linksys router with a fast DSL connection at home (opened up my ports for iChat), and at work I'm connected to our blazing fast network.
    Any ideas or suggestions?
    Thanks,
    Brian,.

    wow, thanks for the answer. It did it.
    At first I thought you said to keep the bandwidth at no limit, so I just made the first change and we still experienced the problem. Then I re-read your suggestion and saw that you said to limit it at 500. After doing that we were able to chat without a problem.
    Do you mind explaining that though? It doesn't make sense to me. I thought that if the video was getting corrupted it'd be because there wasn't enough bandwidth, and the last thing I'd think to do is to cap it.
    Thanks again for the answer, it saved us from total confusion.
    Brian.,
