Conference call dropped

We were able to use conference call for 20 senior management in the monthly meeting. In the last meeting, 8 conference calls dropped middle of meeting.
Nothing changes in existing configuration. I have checked in CUCM Server, System > Service Parameter > Call Manager > Clusterwide parameter>
Drop Ad Hoc Conferenece : Never
Advanced Ad Hoc Conference Enable : True
Great appreciated someone advice me above issue.

Does the call actually end when the conference drops or does the audio just stop (one way or no way audio)? If you have Call Detailed Records (CDR) enabled you can check the disconnect reason of the call. If you don't and you have detailed call manager traces you can take a look there to see why the calls dropped if they actually cleared the call.

Conference calls not connecting/dropping

i am having issues using my conference calling feature on my iphone. The second and or third call gets dropped about 30 seconds into the call. Is this morelikely a ATT issue or an iphone issue?

I as well. 2nd caller get's hung up on when trying to conf to the 1st caller.
No options for releasing callers, or holding all but 1 for a private conf, then re-joining, etc.
My Droid does a way better job!
What gives Apple/Verizon - what/when's the fix?

Unable to make conference call + calls dropping with iPhone 6? :(

I have an iPhone 6 and i keep experiencing my phone calls randomly dropping out on me. I would sometimes hear a beeping noise and then a 'call failed' message would appear on the screen. Other times the call would just cut off and the screen would go back to the caller information or the home screen. Second problem is that i cannot create a conference call. Please help!

Hi ,

The dropped calls, is this the one area?
Do you have any problems with texts?
Thanks.

Drop caller from conference call using Agent Desktop

Is there any way to drop a caller from a conference call using the Agent Desktop like we can do with the ConfList on the physical phone?

No there is not.

How can I merge conference calls and hang up on one of the instead of both on iOS 8.1.1

How can I merge phone Calls and make conference calls with iOS 8.1.1 and hang up on one instead of both of them , it's not giving me an option like before on iOS 7 ?

The following from the 8.1 user manual (http://manuals.info.apple.com/MANUALS/1000/MA1565/en_US/iphone_user_guide.pdf) may help
Create a conference call. While on a call, tap Add Call, make another call, then tap Merge Calls. Repeat to add more people to the conference.
    Drop one person: Tap next to a person, then tap End.
    Talk privately with one person: Tap , then tap Private next to the person. Tap Merge Calls to resume the conference.
    Add an incoming caller: Tap Hold Call + Answer, then tap Merge Calls.

Conference call on Iphone

I don't understand how to combine 2 calls for a conference call. I tried the Merge Call button (from memory, I think that is what it is called), and all it did was put one on hold and connect me to the other person, back and forth, it would not combine the calls.
Does it matter who calls in vs me calling out?
Can u walk me through the steps and are there any surprises?
thanks
bob

Check the iPhone manual, page 50 http://manuals.info.apple.com/enUS/iPhone_UserGuide.pdf
From the Manual:
Conference Calls
You can talk to more than one person at a time, and merge up to five calls, depending on your carrier.
Note: Conference calling may be an optional service in some countries. Contact your carrier for more information.
Create a conference call:
1 Make a call.
2 Tap Add Call and make another call. The first call is put on hold.
3 Tap Merge Calls. The calls are merged on one line and everyone can hear each other.
There is also a graph there that lets you know about adding and dropping more, but I'll let you read that yourself.
Hope that answers your question.

3-Way Calling/Conference Call needs to be imrpoved asap!!

Well come on verizon please fix this problem with the 3-way calling. Im only able to do one 3-way and thats all. only one time during the call. if the other line ends i cannot make another 3-way. I dont even have the option to end one line of the conference call. Im just stuck in conference mode. You should be able to hit conference and then something will show up and let you end one line. I used an AT&T iphone 5 and it works so much better. You have the option to end whichever line you want and you can add another line if u wanted to. Verizon you should be able to make it work like the At&t iphone. With the old basic phone im able to make as many conference calls as I like by just keep hitting the send button. I didnt pay $350 for an iphone 5 that doesnt have good 3-way calling features. Please improve ASAP. It should be like the AT&T iphone 5. When is the fix gonna happen becuase it has been like this for a long time.

Huh! You're right (even though that's not claimed in the specs).
I still detest the idea of having to run twin modems/radios to to voice & data.
There are 3 things that really bug me & may lead to me leaving Verizon:
1. The stated issue with multi-party calls (which this thread was about before Ohio & I hijacked it for a iPhone/Droid voice & data discussion.)
Even though I don't often have 6 lines going at once, the ability to merge incoming calls seems like a really basic functionality that I used to use quite frequently.
2. When I dial conference lines # have the passcode dialed as part of the number I used to be able to put: phonenumber,passcode.
This on AT&T (or any GSM or UMTS network) dials the number (silently), waits until it connects, dials the passcode.
On verizon, this seems to dial the number silently, start dialing the passcode to a ringing line.
OK: add more pauses...
but now it seems to dial the passcode silently (like with the phone number, which the system accepts) AND with tone. This would be OK if they were in sync, but they're not. I get: Thanks for calling, please enter your passcode: "beep!" Thanks, you're now connected. --and the rest of the people on my conference call hear the remaining beeps and boops until the passcode is complete.
#VZFail
3. Voice & data.
It's actually the one I care the least about, but it'd be nice to have a call AND use my phone for a mobile hot-spot. I know VoLTE will fix this, but I'm shocked to hear AT&T may beat VZ to the punch on this since Verizon has had LTE since just about forever.
(In fairness, AT&T has been less than ambitious to deliver LTE because their "3G" is 72Mbit capable & LTE is 100Mbit. VZ's 3G is single digit Mbit & LTE represents a huge jump. --and AT&T's 3G network can do voice + data with 1 radio, hold 6 calls at once, merge/unmerge any line at will. --you just get dropped calls.)
*sigh* Why can't I just have it all?!

Conference calls technical issues

Hi. I wonder if you can help me. My question and issue is perhaps better dealt with via phone, however, I can give it a shot here: I make group calls from my second account. We have a process whereby the host for the call rotates every week (on average).
Last couple of times someone else made those conference calls, we had a lot of technical difficulties, dropped calls, muted sharing, disconnections and such.
Why is this happening? How can we overcome our challenge?
Thank you in advance for your support.

If asking for help you need to provide full details and not just the problem.
Call control agent?
version?
If CUCM, SW CFB/HW CFB?
By what you mention it sound like codec issues, so start looking into that in first place.

Why does my call drop out (one ring only then cuts...

I had an important conference call - dialled the +1 852 number but call keeps dropping out after 1 ring. Not very good!
Solved!
Go to Solution.

Hi, GCA, and welcome to the Community,
Not all conference call bridge systems recognize Skype calls; this detail depends upon the land line telephone network and/or the particular conference bridge system. I have read similar reports of callers not being able to use multi-tiered insurance company telephone systems, although I have not had this experience.

SPA3102 PSTN calls dropped

I have inserted an SPA3102 between my regular telephone and the PSTN line, and find that the calls are being dropped with regular monotony (and this doesnt happen when the SPA3102 is not in the equation). The calls tend to be conference calls where I am listening rather than speaking. The Info page shows that the last PSTN disconnect reason to be 'PSTN activity timeout' and the PSTN activity timer is set to '30000 (ms)', although I am not aware of any breaks in the conversation when the line gets cut off - it can even cut off when I am speaking? The line simply goes dead and then I get the UK 'unobtainable' tone.
Can anyone provide advice on how to rectify this?

UKfarmer wrote:The last couple of disconnects the PSTN disconnect reason is CPC signal, so the nature of the disconnect seems to be varying. Is it safe to switch off both CPC and long silence detection?You should read about CPC as to what it is. This web site has a summary: http://www.sandman.com/cpcbull.html Switching it off affects the ability of the SPA3102 to detect when a called party has hung up. There is also a setting for the minimum duration of the CPC.>how would I switch on syslogging to track in detail what is happening?You download a syslog program and run it on your pc, you put your pc's ip address on the SPA's system tab, you set the Debug Level to 3 on the SPA's System tab, and you set the Sip Debug Option to FULL on the Line and on the PSTN Line tab (on a SPA3102). You can download a syslog program on this web site: http://www.sipura.net/Documents/faq/Section_2.html#9
Edit: Looks like Linksys abandoned the sipura web site, anyway you can't download the program right now. There is a free Kiwi syslog program that works OK. Search for it.
I have also tried a VOIP call into the SPA and out over the PSTN line. In this configuration I can hear the remote party but they cannot hear me.There is quite a bit written about that common problem. It is a NAT Travsversal problem caused by your router. Search the forums for one way audio.

Verizon conference calls iphone 5

I have switched from an ATT iphone 4s and LOVE verizon's call quality and speed of call-call connection. And I knew that I would have to sacrifice the no simultaneous data/voice party that ATT does.
That said, Verizon's conference call ability is AWFUL. With ATT you have full control over each call you are connected to, can drop only one at a time, switch etc.
with verizon it seems buggy to no end, even sticks on "conference" when a caller hangs up so you can't call someone else. very unimpressed and conference calling is extremely important for my business.
just making sure this is how it is rather than a glitch?

I hate the AT&T voice quality. Just bought the Verizon for comparison and found out:
1. Verizon voice is superior to AT&T
2. AT&T iPhone 5 setting has functions that Verizon iPhone 5 does NOT have such as call forwarding, call waiting, show caller ID, etc.
3. Verizon conference calling is primitive just as dreborn1982 has described. Further more, when you have an incoming call.... you can not conference anyone.... "merge" is simply gray
AT&T is so bad that last week I called them to disconnect and was willing to pay the penalty. They offered me the free microcell. I have installed it and the bars jumped from 1 to 5. As impressive as it looks, the calls were still so bad that I went to buy a Verizon iPhone 5.
The Quality of Verizon is noticeable immediately but the feature limitation is annoying.
I will probably prefer the Verizon quality with the limitation.

Conference Calls

Hi,
I'm trying to figure out how to do the following on 4S: when I have a call going with one party and I add another party to the call, there isn't a way to drop the second party (as may be required for example if second party called goes into VM) without killing the whole call. Until recently I was using a Blackberry on VZW and could achieve this by using the "Flash" function in the call screen (so I know it is not a newtwork issue) - but there is no "Flash" function in the 4S calling screen. Can anyone help?
Thanks,
YO

you can't do this on verizon, not with the iphone 4s, or even with the iphone 5 or samsung galaxy 3s...it does not work on the latest and greatest phones or with CDMA or 4G LTE.
i'd be amazed if this actually works on a verizon blackberry - go to a store and have them demonstrate on a phone to verify. i bet it will not work.
this exact thing kills me every day. I do software sales and need to do multiple conference calls per day. if i have a colleague on the line, we try to call another person and get their VM, I have to hang up and re-call the colleague. it's a bummer.
my colleagues, even ones with the same phone as me, can all do these basic actions. i cannot, not even on my iphone 4s. i went to the verizon wireless store and the sales reps there tried to do these actions on their iphone 5 and samsung galaxy 3s. no dice. the network does not support advanced features of conference calling even on 4g lte.
these are some other limitations i struggle with every day with my phone related to conference calls:
you cannot select individuals on a call you initiate to drop them or mute them. you have to have them hang up (and hope they did not just mute and pretend to hang up).
you can only dial out to one person to do a conference call, so you are limited to doing only one 3-way call.
you also cannot add someone in to a current call...so if someone beeps in to a conversation, you can't add them into your current call to make it a 3-way call
also if you are on a call, someone beeps in and you put the original call on hold, then you return to that original call, you lose the option to do a conference call.
