Ichat audio

I have ichat AV 2.1 on an iMac with OS 10.3.9 with an ethernet connection to an airport base station connected to a BT voyager 205 ADSL router.
I can use ichat in a text mode and I can chat in audio to other computers on the local network but I haven't had any luck getting an audio connection across the internet. With one buddy with a pc I don't get a phone logo at all, another with a Mac will try to connect but gets a 'did not respond' message.
I've seen that there may be problems associated with firewalls and routers
http://docs.info.apple.com/article.html?artnum=93208
http://docs.info.apple.com/article.html?artnum=93333
I don't have a firewall turned on on the iMac (maybe there is one on the base station?) or the problem could be with the router its not on the list of 'qualified routers' - if so not sure if it is possible to reconfigure.
Alternatively, my set up may be fine and the problem could be at the other end(s).
Any helpful suggestions?

Hi Ralph,
Just to confuse things, I'm also called Tom.
The advice you gave in this discussion is the closest thing to a solution I have found in dealing with my problem (same as Tom's above), and would love the opportunity to ask you a few questions in the hope that you will check this discussion again...
My parents have the 2mbps BT Broadband deal with a Voyager router, and I assume that it is the 205 ADSL, but I'm not sure right now.
We are unable to iChat AV (audio/video), but are able to iChat (text) with the iSight unplugged. Cannot iChat with the iSight plugged in at all.
I took my mum through the steps in the article you recommended (portforward.com), but at that time we didn't know about the other 21 ports.
I have looked through the portforwarding steps again and it seems that we must first have a static IP. Is this correct? If so any idea how to set it up as the instructions only relate to Windows machines?
My parents are using an iMac G5, plugged straight into the router. OS X 10.3.9 / iChat 2.1. iSight. That's everything I think...
I am I right in thinking that the BT router may be the reason why we are getting the 'Tom did not respond' / 'Mum did not respond' messages?
I am able to iChat AV with the testing AIMs (tryichatav & ichatAVtesting), but have yet to try with a real person.
So the burning qyestion is do you think it would be worth me convincing my mum to go through all 22 ports? i.e. do you think that is the problem? If so do we need to do anything about a static IP address?
Kindest regards and thanks in advance,
Tom

  • Ichat audio and video problems, error 8

    I've been reading the other ichat posts, and it seems that I have kind of the same problem. I can't get audio or video to work with iChat. I can send or receive invitations, but then it gives me an "error -8" message and the attempt fails.
    I have a new computer, so this is the first time I've tried to do iChat audio/video chats. I connect via DSL with a Siemens speedstream modem connected to an Airport.
    Any help/suggestions would be greatly appreciated. Thanks!

    What is your internet up and download speeds?
    http://www.speedtest.net/
    Sounds as if you need to adjust a few settings:
    Navigate to:
    System Pref>Quicktime>Streaming = 1.5
    iChat>Pref>Video>Bandwidth limit=NONE
    Try making those adjustments and let's see what happens.
    Feel free to chat with me, my AIM screen name is the same as on here.
    Good luck!

  • Ichat audio and video problem

    my ichat audio and video don't work with any of my friends, no problems with a text chat, i'm using tiger and they all have leopard, all macs are up to date, i've tried messing around with the ports, firewall is off, internet sharing is off, i know a lot of people are having this problem, are there any answers to this that actually work, i'd appreciate any help

    Hi Ben
    Welcome to the  Discussion Pages
    Presumably you mean this Linksys is set to Not Block Pings on the WAN port (Or whatever phrase your device has) ?
    I also presume that you have done the Quicktime Setting that Steve mentions above ?
    I presume the Linksys is the modem as well and it is doing UPnP ?
    At this stage I have two suggestions.
    1)
    Shut down the computer and remove the Ethernet cable (modem or computer end does not matter) (Make sure it will not connect Wirelessly when restarted before hand)
    Restart the computer
    Restart iChat.
    Reconnect the Internet
    Log iChat in.
    2) Try a reinstall of the COMBO version of the 10.5.2 update
    Both of these suggestions have been used in previous iChat's when other things have not worked and the set up appears OK on the surface.
    Also try
    3) Rebooting the router and a Modem if separate.
    4) In System Preferences > Network > Connection method > Advanced Button > DNS tab add the DNS servers of your ISP
    DO them one at a time so you know which one works.

  • IChat audio drops off

    I've looked about, but can't seem to find anyone with a similar issue, my iChat audio drops off.
    I spend long hours on video iChat and for no apparent reason, after a while, my fiancée will think I'm being quiet.
    I can open the Audio/Video preferences and the sound meter bar will be unresponsive to all sounds.
    I go into the computer sound settings and the input bar will be active, jumping up and down the meter with any sounds made.
    The only way I seem to be able to regain the sound it to quit iChat and open it again and then recall my fiancée.
    Does anyone know a cure that will stop this happening, it's been going on since updating to 10.7.3

    Hi,
    As there are no actual volume settings in iChat itself there is obviously some sort of Capping mechanism or some process that does not fire properly.
    On the whole I tend to keep my computer volume Low  and use this AppleScript to increase the Volume (output)
    Some while ago I added the Input volume line:-
    using terms from application "Messages"
    on av chat started
            set status to away
            set status message to "In Conference . . ."
            delay 0.2
            set volume input volume 85
            delay 0.2
            set volume output volume 50
            delay 0.2
        end av chat started
    end using terms from
    this needs to be stored in your Home Library/Scripts/iChat (or Messages folder) and linked to in iChat  > Preferences > Alerts by changing the top item to  Video Chat Started and enabling the Applescript option and linking to the Script.

  • No Internet iChat audio or vidio on 2 out of 3 Mac's but works on Bonjour?

    I have 3 Mac's on my local network routing through a Belkin router to a DSL modem. iChat audio and vidio will not work with my internet buddies on my MacMini or my MacBookPro, but works fine with my Bonjour buddies. Sounds like a router port problem, BUT my little iBook G3 also running 10.4.9 connects both audio and video iChats on both Internet and Bonjour buddies with no problems.
    The firewalls and Quicktime streaming settings are the same on all 3 machines. I don't know where else to look. I assume that the router ports are OK if the one machine can get through.
    The MacMini worked fine a month ago on a different network, but with the same router. The modem there was for cable broadband. The MBP is new and this is my first try with it.
    Anybody have any suggestions where else I can look for incorrect settings?

    Hi Kamx3,
    How are the ports enabled in the router and the modem
    Which device if any is the DHCP server ?
    It sounds like Port Forwarding or DMZ has been set up
    for the one computer that works.
    You will need a method like UPnP that allows several
    computers to use the same ports.
    10:57 PM Tuesday; May 1, 2007
    Thanks for the feedback and sorry for the delay in responding. The router is a Belkin Wireless . I don't know anything about the DMZ, or UPnP of which you speak. It seems to me that everything worked when I was using the Apple Airport - figures. I'll do some research on these topics to see if I can figure it out. I'll have an opportunity to try it on an Airport this weekend. Thanks again for the tips.

  • IChat - audio and video chats not working to the UK

    I'm trying to do an audio and/or video chat with my Mum who lives in the UK. We're both using the same version if iChat A/V (3.1.5)
    However, we've been unable to succesfully connect. Whether she invites me to a chat or I her, we both get a message saying the other person failed to respond, even though we're both accepting the invitation.
    I have no problem audio/video chatting to anyone else and it also work with my Mum through Skype or Yahoo Messenger.
    Any ideas?

  • IChat audio/video not working: bonjour over computer-to-computer network

    My girlfriend has a brand new MacBook Pro 15". I have a 3 year old PowerBook. Both running 10.4.9 and iChat 3.1.8. We are currently sitting right next to each other, and yet have been unable to connect to an audio or video chat by any method.
    To completely eliminate the router from the equation I created a computer to computer network which she joined. Both of us have our firewalls off, and both of us have our Quicktime streaming speed set to 1.5Mbps. We tried to create an audio connection over Bonjour. I got an error -7 and she got an error -8.
    There are many threads reporting the same error, but most of the solutions involve changing router settings. I figured that since this is on a computer-to-computer connection there is no router involved. It would be nice to be able to get this working over the general internet, but I figure if it doesn't work in this very limited setting it will never work. Any help? Much appreciated.

    Yep - did that on both computers, to no avail:
    Here's the first section of the error messages from both computers. (I can post more if it's helpful.)

  • IChat Audio and Video not working correctly...

    Hi.
    I recently upgraded to Snow Leopard. Before upgrading, I was able to video chat with little to no problem with family over iChat. I just tried it again today for the first time since upgrading to Snow Leopard and the audio is barely working (can only make out every few words, if that), and the video is extremely distorted to where you can sometimes not even tell there are people there. It gets all pixelated and weird. I tried doing the chat with Google Talk and then again with Skype, and had just as many problems with those. My family is using a Mac with an older OS, and they can see and hear me perfectly fine. I'm not sure if the problem is with my computer or with theirs, or if it's just a communication problem, but any ideas would be really helpful. Thanks!

    After iChat developed missing audio and video pixellation problem post Snow Leopard installation at my mother-in-law's machine (and ours), I tried the usual decrease the bandwidth fix to no avail.
    The solution that actually fixed the probem was to turn off port forwarding protocol on her Time Capsule and our Airport Extreme. Things are now working smoothly even at 500 kbps settings on both ends.
    An interesting aside... Turning off port forwarding for ssh to her machine doesn't kill the ssh port tunnel from the outside LAN to her mac. It looks like iChat and the Time Capsule keep an incoming ssh tunnel open even if you have disabled port forwarding on the Time Capsule. I suspect this "secret" opening of ports is the magic of why iChat and screen sharing have been so much easier to set up when a Mac is behind an Apple router. 3rd party routers need ports manually forwarded to the Mac. Apple routers just worked ---- and it looks like Apple does it by invisibly opening ports on their routers when a Mac runs iChat.
    Pretty nifty, but also silently opens a security hole that you may THINK you closed. SL seems to trip up over this arrangement when you also turn on Port Mapping Protocol and manually assign ports to forward.
    At any rate, it wasn't the data rate, it was a new bad interaction between the Apple Router's Port Mapping Protocol and iChat 5. Turn off PMP on the airport and all becomes well once more.

  • 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:
    11.657163 @/SourceCache/VideoConference/VideoConference-415.13/SIP/SIP.c:2917 type=4 (900A0015/0)

    Cheers

    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.

    Hi,
    Mark should go to the set up pages of the Airport he has and in the Internet icon/Pane > NAT tab he should have Port Mapping Protocol turned On.
    If he has the much older firmware I will need to see pics (again) to remind me.
    The other potential issues is what modems are John and Mark using in front of the Airport base Stations ?
    Are they routing modems ? Cable modems tend not to route and DSL one do.
    They should not have two DHCP servers on their LAN's ( A Base station set to "Share An IP" will be doing DHCP and a routing modem will most likely be doing it by default)

  • Ichat audio/video

    I know many people have posted their issues with ichat's audio/video, but I haven't found any solutions that would help me. My problems are, every time I open ichat's preferences and try to click on 'Audio/Video' ichat crashes, you can probably guess that I also can't video chat with any of my peers, nor can I screen share. A couple of months ago I was able to, I'm not sure if there is any relation, but ever since I set up time machine through my AirPort Extreme Base Station, thats when I noticed problems. If any additional info is need to help solve my problem please let me know. Thanks for the help.

    Hi,
    Log on to the Airport base Station using Airport Utility (Application/Utilities).
    Use the Manual Configure button.
    Go to the Internet iCon/pane.
    Select NAT tab
    Enable Port Mapping Protocol (You do not have to set ports)
    From the first part of the Internet Pane make sure any DNS server listed are copied or show in System Preferences > Network > Advanced Button > TCP/IP tab.
    In that same place turn Off IPv6.
    Post back with results as we may have to get you to delete a .plist to get ichat to be stable.

  • Ichat audio video options for google accts

    Hi,
    1. I use ichat with my google account. I was wondering if I could do an audio and video chat from this account?
    2. Also, if I disable my camera (in format tab), and press on the audio option beside my picture in the chat list, why is isight cam getting turned on? Shdn't it be disabled and only microphone be turned on?

    Hi,
    Re 1)
    If you are your Buddy are using iChat with any Jabber ID including Googletalk then you can do Video and Audio Only chats. This is because no matter which Buddy List you start from iChat uses the same A/V Protocols.
    What you can not do is Video chats to the PC App for GoogleTalk or to any Buddy logged in on the WebMail Google pages, both of which can also do A/V chats but uses different protocols.
    Re 2)
    The Video Camera is turned Off in the Video Menu at Camera Enabled and toggling it so no tick shows.
    Yes when it is turned Off (Deselected) the icon next to your name should show the Audio icon (Telephone handset).
    The camera will however get turned on for the Preview even if the camera is turned Off. A preview of the Audio would not "Show" anything as iChat does not allow play-through of the live sound.

  • Intermittent iChat audio input problem

    Hello all,
    One client has an Intel Mac mini (Macmini3,1) with an external iSight camera running 10.6.7.
    We can be having an audio or video conference, or a screen sharing session, and it will work fine for a long time.  After a while though, for reasons that I have yet to explain, his sound input will simply change to where I can only hear him if he is shouting.  When I go to the System Preferences, I can check his sound input volume and it can be turned all the way up, but he still cannot transmit any sound unless he shouts.  The sound input level also jumps normally on his computer, but that sound that is making the input level jump does not get sent through iChat unless it is very loud. This will persist until he reboots the computer, at which point it will be fine again.... for a while.
    The only thing I have noticed in the console are:
    [0x0-0x23023].com.apple.iChat[229]  resetting echo canceller
    iChat[16487] attribute = {
    VCSupportARDAudioMux = 1;
    shouldFindExternalIP = 1;
    0x0-0xcd6cd6].com.apple.iChat[16487]     resetting echo canceller
    Any ideas?
    Router issue?
    When we talk we are usually speaking on MobileMe and we have encryption enabled.....
    Thanks

    Hi Ralph,
    In the System Preferences > Sound > Input does the blue bar seem to be alway "On" to some degree ?
    No
    Could this be explained by the Camera mic picking up the computer's disk noise ?
    I don't think so.  The Mini is pretty quiet and the iSight is on top of the monitor held in place via the magnetic holder
    Does it do better on a rubberised mouse mat ?
    The iSight cam?
    Does the same Preferences get the Ambient Noise Reduction button even though it has no internal Mic ?
    No, there is none when iSight is connected and selected
    If it does try chaing it between Off and On.
    Any MIDI input connected ?
    sometimes, but never when we chat.  a keyboard for garageband.
    If so check this is at 48000 as the sample setting for the External iSight. (May may to check this anyway).
    In the Audio Midi Setup right?  will do that next time it is plugged in.
    Will try to recreate that playlist as well.
    Thanks as always...

  • Ichat audio chat not working

    every time i want to audio chat with a friend it starts connecting then i wait for about 30seconds then it says that it cant connect because the guy im talking with says that he acsepted my invite but ichat said he didnt please help

    Hi,
    Welcome to the    Discussions
    Presumably the Pop up Log (Use the Reveal Triangle "Details" on th e left) said it was an Error 8 issue ?
    It would help to know of the Buddy is on AIM for PCs, a different iChat version.
    If you have the Mac Firewall ON (System Preferences > Security > Firewall) then you have to go to the Advanced Tab and set "Allow Signed Apps" and have iChat in the List. Stealth needs to be Off as well.
    This will allow iChat through the firewall.
    You also have to get it through your Router (Or routing modem).
    This requires that you open or allow the ports that iChat uses.
    If you want to use the iChat Screen Sharing then set your devices to use UPnP (Universal Plug and Play) which will allow the app to tell the router which ports to open.
    Not all devices have UPnP and you may need to use either Port Forwarding or Port Triggering (depending how many computers you have to use iChat over the same connection).
    You may also need to turn Off Ping Blocking and any Intrusion Protection (Denial of Service in particular)
    The ports are:-
    ||iChat Ports||TCP||UDP||
    |AIM|5190|5190|
    |A/V|none|5678, 16393-16402|
    |Bonjour|5298|5297, 5298, 5353|
    |Jabber|5220,5222, 5223|none|
    Note this is the iChat 4 and 5 Range
    Add port 5060 UDP for iChat 2 and 3 and extend the group of 10 to 16384-16403 (20 ports)
    iChat 4 and 5 also uses an undeclared Random port to do the Screen Sharing part and works if you can and do use UPnP (Or Port Mapping Protocol) to open ports in your routing device.
    If you have Error 20, 21 or 22 showing in the first paragraph of the Log then you have a different problem.
    Of course similar things ought to be done at the Buddies end.
