  • Jabber for iPhone and iPad cannot receive calls

    We currently have Call Manager 9.1.1 and Presence 9.1.1.
    I am starting to use the Jabber Client for iPhone and iPad, but am having trouble receiving calls dialed to a particular extension.
    If I can go settings for the iPhone Jabber client as an example, I am succesffuly connected to all accounts: IM, Phone Services, Voicemail, and WebEx.
    When I go to the keypad, I can succesffuly dial internal extensions and make outbound calls to any numbers and they come accross as using my extension.
    When calling the extension, my desk phone rings, but not the Jabber client.
    Not sure what could be causing this issue to occur for Jabber not receiving the calls.
    Thanks for any suggestions.
    Paul Gaydos 

    Should still work. But would be good to check indial into jabber with the phone unplugged, just for testing purposes.
    also, you have checked the partition and configuration on the TAB device is the same as on the deskphone?
    Can you attach call manager traces when making a test call and attach to the case.  Let us know the extension and device names you have used in the test, and a timestamp of the test.
    thanks

  • Jabber for iPhone cannot call over Expressway. Expressway says: Bad Extension

    Hi,
    I've had Expressway working but now calls from/to Jabber for iPhone fail with a message "Bad Extension" in Expressway-E.
    Is there someone that is willing to share the search rules of Expressway-E required that are required for Jabber to make/receive calls. I think I accidentally deleted one or changed one.
    Regards,
    Erik 

    Yes, I got an answer from TAC and it is was the solution to my problem.
    It had to do with announcing IPv6 support by the clients. (header "Requires: anat")
    By creating a new Common Device Configuration that disables IPv6 (IP Addressing Mode), thus IPv4 only, and assigning this common device configuration to all devices using MRA, solved my problem.
    Let me know if this also fixes your problems!

  • Transfer VOIP Calls Between Cisco Desk Phone and Cisco Jabber For IPhone 9.5

    Does anyone know how to transfer an active voip call from a Cisco IP Desk Phone to Cisco Jabber for IPhone?  I can transfer a call from Cisco Jabber for IPhone to my Cisco IP Desk Phone no problem.  I put the call on hold and then click "Resume" on my Cisco IP Desk Phone.  However I cannot do the same but the other way around.  If I put the call on hold on my Cisco IP Desk Phone, I see "no active call" on my Jabber client.  The only information I could find slighlty relevant was using the Mobility Key/Remote Destination Profile feature however this defeats the object as this will forward to an external number, e.g. mobile and I just want to transfer the call within the VOIP environment between the two devices that are using the same directory number.
    I am using Cisco Call Manager 9.1(2), Cisco Presence 9.1 and Cisco Jabber for IPhone 9.5.
    Any help would be greatly appreciated.
    Kind Regards,
    Paul Parker.

    Did you ever find an answer to this ?
    I am seeing the same behavior and trying so see if I can put calls on hold and pick them up both ways also.
    The only answer I seem to have found is to use park instead
    That would/should work but I would just prefer to hold/unhold
    Just not sure why we would not be able to hold/unhold on what is essentially a "shared" line
    Does anyone have this working for them ?

  • No "touch to return to call" option in Jabber for iPhone

    I noticed that when I'm in a Jabber call and I press the home button on my iPhone, the call stays up audio only but there is no indication on the iPhone that I'm still in a call.  When you are on a regular PSTN call on iphone and you press the home button, there is a green notification message at the top that says "tap to return to call".  Is this possible with Jabber for iPhone?
    Thanks,   Mike

    All of those are configuration issues, go thru the config guide once again and review it step by step and make sure it's all properly configured.
    Jabber is not registering to CUCM, it has not been configured as a softphone, or the deskphone association is wrong.
    If you can see the DN info from the users but not able to call, then at least your directory integration is fine.
    DNs not reachable is again a config problem with call routing, CSS and partitions.

  • After update to IOS 4.3.5 my Iphone incoming and out going calls is not working properly and I have to remove the SIM regulerly to conduct or receive a call

    after update to IOS 4.3.5 my Iphone incoming and out going calls is not working properly and I have to remove the SIM regulerly to conduct or receive a call
    It is not practicale to do this always any one faces the same problem

    There may be a problem with the SIM card. Get a new SIM card from your carrier - there should be no charge for a replacement.
    If no change with a new SIM card, the standard troubleshooting steps in order are:
    Power your iPhone off and on.
    An iPhone reset, which is done by pressing and holding the home button and the sleep/wake or on/off button simultaneously until you see the Apple logo and then release.
    Restore your iPhone with iTunes from your iPhone's backup.
    Restore your iPhone with iTunes as a new iPhone or not from your iPhone's backup.
    If no change after any of these steps in order, your iPhone has a hardware problem.

    Also in the CUCM you can see the attempts to register (so discard connectivity issues) that are seen from the CUCM
    The error received is UNABLE TO CONNECT
    any help would be appreciated.
    thanks in advance.

    Hello
    I have same your problem but I didnt change or add anything from CUCM 9 all configuration as default.
    thanks

  • Jabber for iPhone force auto-connect

    Hello,
    Does anybody know if it is possible to force Jabber for iPhone/iPad to connect to a wireless SSID network as soon as it is available?
    We recently implemented Jabber and we are noticing that some times, users arrive to the office, where corporate SSID is available, but even if jabber is running on the background, it won't automatically reconnect to the network.
    User will have to manually open the application and wait for Jabber to reconnect.
    Is it possible to make this process automatic for the user?
    Regards,

    CUCM version is 8.6.2.
    Presence version is 8.6.4
    Jabber for iPhone & iPad is 9.6.2
    The issue is that if Jabber is running on iPhone's background, even if wireless connection is activated, it seems to disconnect. In order to reconnect, user has to manually open Jabber and wait for the connection to establish, especially to make calls.
    The same applies when a user is running Jabber, he arrives from outside to the company and wireless reconnects to corporate SSID. Jabber won't automatically reconnect until user opens the app.
    Regards,

  • Jabber for iPhone 6 - version 10.5 on iOS 8

    Hello All,
    Just wondering if anyone has the same issue as me. I had an iPhone 4S and use the current version of Jabber for iPhone with all services on it until yesterday when I got my iPhone 6. On the iPhone 6, however, I cannot get the client to register to CUCM. All other services including voicemail, and IM & presence work just fine - I just cannot make phone calls.
    THe error I get is "Failed to Get Device Configuration".
    Our organization is running CUCM 8.6, CUP 8.6, and Unity Connection 8.6 (upgrading soon :P)
    Just as an FYI, I am using an iPad 3 with Jabber 10.5 and can register just fine. Previous to getting an iPhone 6 it also, worked just fine.

    I am currently running jabber 10.5.0.189050 with iphone 4s ios 8.0.2  I have seen very little issue with this so far.  My backend cisco servers are at the latest 10.5 code (CUCM, UNITY, Presence,etc) along with latest version of expressway.  If you say you are not supporting this then what is currently supported as I have a large sales team that we are planning to deploy this to soon, mostly running iphone 5's and a mix of ios 7 and 8.  New employees coming in on iphone 6 and ios 8.0.2  If you can't tell me here then where to we find up to date accurate information.
             thank you ,  jeff magnuson

  • VCS Expressway event log errors when Jabber for iPhone and Windows log in

    hi folks,
    I've deployed Collaboration Edge with VCS Control and Expressway:
    my Jabber for iPhone succesfully can log in from Internet and it can IM but not calls and I see next messages in VCS Expressway when Jabber is logging in:

    "Digest User" in the "Protocol Specific Information" section of Phone Configuration selected right user. in this Jabber I see following error "Failed to get device configuration". however Jabber for Windows and for Android hasn't such issues - they succesfully can log in from Internet and it can do calls and IM but I see next messages in VCS Expressway when Jabber is logging in. The same log line appears when Jabber for Android log in:
    tvcs: Event="Inbound TLS Negotiation Error" Service="SIP" Src-ip="Client-in-the-Internet-IPaddress" Src-port="56751" Dst-ip="Expressway-IPaddress" Dst-port="5061" Detail="No SSL error available, probably remote disconnect" Protocol="TLS" Level="1" UTCTime="2015-03-27 14:19:11,769"
    and I can't find any information which describe such types of error.
    thanks!

    Thanks Srini, but the instructions have two options:
    1. Use the Control Panel, select "Oracle 11g..." and uninstall from there.
    This is of course the first thing I tried, but as I said, there is no entry for Oracle 11g in my "Programs and Features" applet.
    2. Download the install package and run OracleXE.exe with the remove iss file.
    Firstly, there is no OracleXE.exe in the package I downloaded, just setup.exe;
    Secondly, setup.exe ignores the iss parameter and tells me that OracleXE is already installed (setup.log contains ResultCode=-3) so it can't be installed.
    Is there somewhere else to get an OracleXE.exe that will work for 11g? Or are these the instructions for 10g and haven't been updated yet?
    Am I unusual in not having a Control Panel entry?
    (and I understand this is a beta - that's partly why I'd like to uninstall it - I'll go back to 10g and not be so impatient :))
    Regards,
    Andrew

  • Where is the documentation for Jabber for iPhone and iPad 9.6.1 ???

    Jabber for iPhone and iPad 9.6.1 was released on Tuesday Jan 14th 2014.
    I see the 4 .cop files on cisco.com  in a zip file copfiles_iOS96.zip. What is the difference between the 4 files?  Application in the AppStore on my iPad, but there are no release notes, or documentation on cisco.com.  All I can assume is that these .sgn files need to go on my Publisher/TFTP server?
    Nothing here about a 9.6.1

    I only see two COP files, one for iPhone (TCT) and one for iPad (TAB). These are required on older (can't believe I'm calling 8.6 older already!) builds of CUCM.
    Which other files do you see?

  • My iphone4 disconnecting calls after 3 rings and show these calls as "missed calls" while the person who calls me still hear a dial ring. this started to happend after i upgraded to ios 7.0.4 please advise

    my iphone4 disconnecting calls after 3 rings and show these calls as "missed calls" while the person who calls me still hear a dial ring. this started to happend after i upgraded to ios 7.0.4 please advise
    this is really frustrating since i cant pick up calls with only 3 rings and i always miss them
    i tried to restore like 3-4 times, didnt help
    even tried to set the iphone as a "new iphone" on itunes and it didnt help

    Generally, when going out of the country and using a foreign SIM, carrier files can be changed. Go to Settings>General>About>and look at Carrier? What does it say? You may have to perform a restore. You can try a restore from a backup, that would reinstall the iOS, and would provide the latest AT&T carrier file as well. See if this will fix the problem.
