CME 8.6 Call Disconnect Issue

Hi All -
My company has a small CME deployment in Australia and yesterday the local network resource made some changes to the network related to other work but following their changes, a very weird problem is occuring on the system.
The site has 4 POTS lines coming in on a VIC-4FXO card and when calls come in, the IP phones ring but as soon as they try to answer the call disconnects. I was suspecting a codec negotiation issue but since the call is coming from the PSTN, I'm not real sure because it should be G.711 which the IP phones should handle fine.
my ccapi debugs show the call disconnecting with the typical 16 cause code (normal clearing). I can provide any part of the config or debug output required for some ideas.....
I appreciate the help.
Tom

Hey Paolo,
I am facing the same issue but only with a single user.
Using ISDN2e (bri). She answers the call and it disconnects, can you please shine some light please

  • CUCM Call-Disconnect cause 47

    Hello all,
         i hve an issue with below senario
    ph1----CUCM====CME=====NortelCs1000----ph2
    1-when ph1 call ph2 , it rings, then silent call, after 12 sec call disconnect
    2-debugging CME, gives; CUCM send disconnect cause 47
    3-tracing CUCM give

    4-call from ph2 to ph1 give the same symptom with same errors
    5-if a phone registered at CME , it can call ph2 or ph1 normally, with codec g729
    please help me to resolve this issue as all users cant call each others

    Problem is likely a codec mismatch.  Do you have MTP checked on the trunk between CUCM and CUCME?  When you make calls from the phone to CME, are you sure it is negotiating G729? 
    47 typically means a transcoder couldn't be invoked when it wanted one.  I would start looking at codec to see if you can find out what the issue is.

  • Wifi disconnect issue w new Mac

    I bought a new Mac about a week ago.  Right away I started experiencing wifi disconnect issues.  I called customer support line and they had me reset the eprom.  I don't recall the key sequence now. The problem went away for a week but has now returned.  Is this a hardware quality issue?

    right my friend, you know this is not an uncommon issue with mac, all my macs have the same issue (macbook, mac pro, mac mini and older imac), i disconnect the wifi and reconnect to sole the issue. it depends alot on what you have thats goign on around you, if there is a lot of wireless networks in your area then this might cause the issue. i improved this problem using a time machine and set the wireless to 5ghz only - it helped. i also bought an airport express to strengthen the network and touchwood this is a rare problem for me now!
    try moving the modem around in case it this - ensure its not on the floor or touching the floor, there are many tips for improving modem connections look on youtube
    however the sequence for this is on

  • Call disconnect on FXO port

    Hi All,
    I have an issue with call disconnect on FXO port. Call are getting disconnected as soon as it connects.
    I observed the call takes the port 0/20 which has the command supervisory disconnect anytone
    but in other ports I see supervisory disconnect dualtone mid-call
    so I have changed with the second and got it working for some calls, In the debug vpm singal debugs I see remote device releases the call. 
    Could you tell me how this works and what are the debugs we could check to see what is the exact problem?
    Number dialled are : 361000, 352788
    Can you check? Logs and sh run is attached.
    Thanks,
    Lajith P

    Beside that what you said Laith - I still think that you need specific tones for disconnect on FXO and only then your voice setup is going to work as it should. I can't comment on different version of IOS-es but maybe your previous one was better in handling this type of problem...if you don't have any specific requirement and must use 15.1 IOS you can always revert back to 15.0 and continue using your ports as already...
    But if I was on your place - I would solve this problem once for all and then you don't have to worry about some upcoming new IOS

  • Skype Calls disconnect my internet.

     Hello, 
    I'm having a really annoying problem here. Skype calls disconnect my internet at random intervals. It ONLY happens when I am in a Skype CALL. I could be gaming, or just minding my own business (staring at my desktop) and it will happen. I've tried several solutions but none of them seem to work. I've disabled uPnP.
    I've used a port anywhere between 1000 and 65000.
    I've checked and uncheck the "Use port 80 and 443 for additional incoming connections" multiple times. It never works.
    Usually what I do is disconnect my computer from the router, and then reconnect it quickly, and it sets everything back to normal. (Normal internet connection). However, if I dont do that my internet will just stay disconnected for an extended period of time. (1-5 minutes, 5 being the longest I've experienced).
    I run on Windows 7.
    I have Microsoft Security Essentials.
    My Skype version is 6.21.0.104
    Please let me know if you need anymore information to solve my problem.

    That sounds like an issue with your router.  Try bypassing your router to see what happens.  If you router has any firmware updates available, apply them.

  • FXO calls disconnect when answered

    Hi
    I've been struggling with this issue for over a month and both I and TAC seem to be stumped.
    I have a customer with a small office that we are trying to migrate to a centralized CCM cluster. They have a 1760V with 4 analog lines that we want to connect to an FXO card. When we connect the lines to the router for testing I get the following behavior.
    PSTN caller calls into the system.
    The IP phone user hears the phone ring and answers the call.
    The IP phone user sees the call disconnect After a second or two, the call begins to ring again on the IP phone If the IP phone user answers the call again, the call disconnects and the process repeats The PSTN caller hears ringback the whole time.
    The problem seems to be that the router is interpreting a disconnect coming from the telco.
    Trace snippet:-

    I've talked to the CO guy but he's been little help. I did have them run a ground start trunk for testing but it exibits the same behavior.
    I've tried every combination of battery-reversal supervisory disconnect etc... that I can think of but I cannot seem to solve this problem.
    TAC does not think its hardware related but I'm going to send a replacement router out just in case.
    I'm hoping someone might have some suggestions for me.
    Thanks in advanced.

    I have seen this problem before where the polarity on the wires were reversed and/or the physical wiring is physically 4 pairs instead of 2. The physical wires going into the fxo ports should be 2 wire.
    Please have the telco verify that the polarity is not reversed [ make sure that verify/re-verify ] as sometimes they claim to check, but are not diligent enough when checking.
    If the gateway is somehow detecting battery-reversal, then it will essentially disconnect the PSTN call leg, which will cause the ip phone to see a disconnect. Next, because the PSTN continues to ring the call, a second call will come in [ from the view of the ip phone ]. To test if battery reversal is causing the problem, you can temporarily disable battery-reversal detection on the voice port by using the following command:
    router#test voice port 1/1/0 detector battery-reversal
    If after disabling battery-reversal, and this problem dissapears, then there is your problem. Please note that the test voice port command only lasts until the router is rebooted.

  • Server Disconnect issue

    Hi,
    I'm getting this mesage from my server:
    A server you are using is no longer available. Do you want to continue trying to contact it?
    Click OK to continue trying to contact the server (server name)
    Click Disconnect to break the connection. If you disconnect you may lose changes you've saved and any applications you have opened from the server may stop working.
    This is a semi-frequent occurrence. Also, we are using a utility called AdmitMac Browser to connect to ur server.
    If anyone has this utility and/or gets this disconnect message I would appreciate some input and any way to resolve the issue.
    Thanks,
    Bob L.

    Here is an update - none of these things really worked long term - the issues returned. I switched to Bing for a while which seemed to help but I missed some of the search results from Google.
    I cross referenced a search with the disconnect issue and VPN (which I use for work) and found that some had to adjust the MTU in the System Preferences>Network>Advanced under the Hardware tab. Normally it is set for 1500 but I dropped it down to 1400 and it worked better and then finally down to 1300 and haven't had the disconnect issue with Google searches on Safari.
    I'll continue to monitor it and if I have any issues I will report back.

  • WAG120N - Frequent Internet Disconnection Issue

    I have bought a Linksys WAG120N few days back & after i got it , i also updated it to the newest firmware from the Linksys site.The Firmware version for my product is , 1.00.12 Annex A.
    But i am getting a  frequent internet disconnection after installing the Router/Modem.I am not a newbie in this.I have done my CCNP with full marks & currently working in IBM India & i have enough knowledge on how to configure Routers.
    I have done the Flashing in the correct process & after Flashing , i did a 30-30-30 Reset as explained in this forum somewhere but the issue is still existing.
    I am listing below what i have done so far. :-
    1) After getting the Router , i have updated to the newest firmware & Hard-Resetted the Router as explained in this forum.
    2) Then i configured the modem with the values from my ISP.I have done it both manually & also tried the Linksys Setup wizard that came on the CD with the Product and the SETUP WIZARD HAS MY ISP ON THE LIST as well.
    3) I got the net connected after configuring but only for some time.After that , i am constantly getting disconnected from the Internet no matter what if i use the Wired or the Wireless devices to access the Internet.I tried setting the Router with both  wireless Security enabled & disabled.No luck in either cases.Almost all of the time i get a disconnection when the DSL Link is Steady on the WAG120N.So, this should not be a Line problem.Also i can access the Net with my ISP provided Modem.No problems at all.
    4) I tried uninstalling the Anti-Virus & the Internet Security program i use which is Symantec Norton Internet Security 2010.No luck.
    5) I have Formatted & did a Clean Install of Windows 7 X64 & Windows XP SP3 & tried running the Router on a freshly installed operating system with no other software installed.I tried different Machines , Different Operating Systems , Different Lan Ports.No luck.
    6) I deactivated Windows default Firewall & every Power Saving functions of my OS.No luck.
    7) Linksys suggested me to visit the Service Center & get a replacement.I did visit the Linksys Authorized Service Center & got a new WAG120N & brought that to my home.I had to pay around 20 USD Taxi Fare as the Service Center is at the remotest part of my city.I wish if Linksys had a Pick-Up & Drop facility which nearly every big companies offer in my place.
    8) The new WAG120N did not change anything.The disconnection issue is still existing.
    9) There is absolutely NO problem in my ADSL line.I am using a 512kbps ADSL connection & when i use the CHEAPEST Wi-Fi ADSL Modem which has been given  by my ISP , i can access Internet just fine , no problems at all either in Wired or the Wireless.So, in this case The Linksys ADSL Router is at fault.
    10) I can see the ADSL line Stats with my 20 USD worth of Huawei ( ISP provided ) Modem but the 150 USD worth of Cisco/Linksys WAG120N does not support showing the ADSL Line stats ( or at least the Firmware doesn't support it ) which is unbelievable for a company of caliber like Cisco.
    The two most important things every Modem at least should display are :-
    1 ) SNR Margin
    2 ) Attenuation
    These two are absolutely a Must-Have features if you want to see how good your ADSL connection is & i am surprised to see that my cheapest ISP modem does have these but a Cisco product does not. !!!!!!!!
    I have called the Linksys support again & they told me that they are Escalating  my case to their 2nd Level.
    I got a response from their Level 2 Support Person & he asked me to provide information about my case & i had sent him a reply 2 days ago but no reply from him.
    And I am NOT the only person with this problem.I do not know Linksys knows this or not but there are several Linksys users who are using this model & are facing the exact same issues as me.
    Here are some of them & they have been posted on this community itself :-
    1) http://homecommunity.cisco.com/t5/Cable-and-DSL/Wag120n-problem/td-p/300397
    2) http://homecommunity.cisco.com/t5/Cable-and-DSL/WAG120N-keeps-disconnected-from-internet/m-p/330870/...
    Tell me Sir , what should i do ? Should i sell it & get another brand or Linksys is going to help me to resolve the problem ? I am extremely sorry to say that i feel regretted that i invested my hard earned money into this which just does not want to work at all.I am too much frustrated & not going to buy any Cisco product if my problem does not get solved because i can not bother the disconnection problem as i need to stay connected all the time for my job & also for my personal reasons.It is a shame that i had to pack my Linksys up on the shelves & have to use the cheapest quality Chinese ( No offense ) Modem because at least the connection does not drop here & I can use it for what it is meant to be.
    I will be expecting a quick reply from you people & would also hope that you will be able to solve the problem.Also i think the problem is not the Router but the Firmware itself is faulty but i am not sure about that because this is my first Cisco product & frankly speaking I am very much disappointed with it.I would very much like to experience a Cisco product because i thought it is an World Class product in the business.So, please help me resolve this problem.Either Linksys should help me resolve the problem and get me an working product or i would want to get my money back.Thank You.
    (Mod note: Edited for guideline compliance.)

    Yes but I think Linksys should give me another one which is working right ? Why should i invest in another Router as i just bought it & its already too pricey here.
    I need an ADSL Wi-Fi Modem Router & there is only three models avilable here.One is this one which i'm using , WAG120N & the other two are  WAG160N & WAG320N & both of them costs more than triple than that of WAG120N.And no one is going to give me a replacement here.I can get the replacement but the same Router.I can not upgrade it without having to buy a whole new router which costs thrice than my current one.
    So, i would be highly oblized if Linksys can give me a replacement because only they can replace it with another model but Linksys India customer Care is only suggesting me that they can issue a replacement for the same model & can not give any other model.
    I sent my concern to the 2nd Level Technicians but have not received any reply.Feeling helpless at the moment.
    My posts are edited & most important parts are being deleted.Please do not edit my post.All i am wanting to get a suggestion for my problem.I do not want to bother you with my problems but the communities are meant mainly for that purpose so that we can help & support each other.
    Thank you.

  • Another speed / disconnection issues thread

    Hi all,
    I'm getting quite frustrated with getting a problem on my line fixed, that's affecting both broadband and telephone service. This has been going on (on and off) since summer last year.
    Using a BT Homehub 2, the connection started dropping quite frequently, and a noise appeared on the phone line - bad enough that I couldn't use it for calls as I couldn't hear what the other person was saying. After multiple telephone engineer visits (about 5 different engineers - it was an intermittent fault, so difficult to trace I believe) they narrowed it down to a section of overhead cable that was rubbing against a tree branch. It took a complaint to BT to actually get this section of cable replaced though. This takes us up to around November last year.
    Since then we had a couple of months of reasonably stable service (the noise had all but disappeared and broadband was connected at a regular 2.5mbps). However recently the noise has returned on the phone line and the broadband issues have also come back (regular disconnects and low speed). Some days it disconnects every 10 minutes for a few hours, and some days maybe 5 times in the whole day.
    The BT broadband technical support line ran a line test about a week ago and decided they needed to escalate the issue to a Level 2 team (whatever that means). They ran more tests and, following their script, decided that my Homehub was at fault. I didn't agree, but decided to humour them. I have a spare ADSL router, and have swapped the BT homehub out for that, with no resulting difference in connection speed or stability.
    I'm currently connected at 576kbps. The ADSL router is connected directly to the test socket, and has been for the last 2 weeks. I have also tried swapping filters. Still no improvement. I called technical support this morning again for an update, and they decided that they wanted to try resetting my IP profile. When I asked them what this would achieve they said that it would fix my speed issue, my disconnection issue, and the noise on my telephone line.
    Now this sounds a little bit ambitious to me - I don't see how a simple IP profile reset can fix all these issues, but I'm not a technical expert and so I'm coming to you for advice. Does this sound like a reasonable course of action to you? My view is that there is still a fault somewhere on the line or in the exchange, but they are currently refusing to send out an engineer to run tests from this end, and are telling me I need to wait up to 4 days for the IP profile reset to take effect before they will consider sending one out.
    Sorry for the long post - any help or advice much appreciated. Here's some noise stats from the router (not a BT one at the moment, but as I said, it doesn't seem to make any difference which router I use).

    Output Power (0.1 dBm):
    166
    123
    Attainable Rate (Kbps):

    Thanks for the quick reply.
    I have re-connected the Homehub to the test socket now. The downstream rate seems to have gone way up (this is the first time I've seen a rate this high since I first connected the Homehub to the test socket about two weeks ago). Just goes to show how much speed the connection loses when using internal wiring - as I said, I used to get about 2.5mbps - but that's a different issue.
    My disconnection / speed issue is frustratingly intermittent, as swapping between the two different routers hasn't made any difference over the last week, with downstream rates of 1mbps or less, but now that you've asked me to do it, typically it now looks much better. Going on my past experience though it won't hold this rate for very long.

  • Skype calls disconnection

    Dear all,
    I purchased skype voip services, and trying to call pakistan from saudi arabia, but during last 4 days my all calls about 30-40 calls disconnect after 1 or one and half minutes. I am using nexus 4 android 4.4.4 and skype latest version. Also skype is not blocked in saudia arabia. Also i tried to make a call from my laptop but same issue. Is there any skype customer support number or email who can check my account and solve this issue

    I have the same problem with Skype calls from Saudi Arabia to landlines.  Strangely, when I call from Saudi to the U.K. or Saudi to Switzerland I get clean, uninterupted phone calls.  When I call Saudi to the United States the calls are disconnected after a bit more than one minute.  I suspect the local telecom is doing this to discourage Skype users.  Does anyone have the same experience making Skype calls from the Kingdom?

  • Iphone 6 call quality issue....

    Hi, yesterday i saw software update in my iphone 6 and i thought it will solve the call quality issue , but unfortunately it was not for that.
    Dear iphone support , the call quality in iphone 6 is really bad, I was using iphone 4S and that had great voice quality. iphone 6 voice during call is not clear , it has noise .
    When I told my friends about the problem , they told me that I might have bought the refurbish phone. But I bought it from Dubai in 750 USD and I do not think it would be the case.

    Since my iPhone 6 has great Call Quality,
    My tip would be to take it to an Apple shop. All apple Products have world wide warranty.
    If it is really they should be able to fix it.
    Hope this helps,

    Sorry to hear that.
    As alexdon says, this sounds like it could be network related. Have you been in contact with your operator about this? Does it happen both on GSM only and WCDMA only? You can select this under Settings -> More -> Mobile networks -> network mode.
