Unable to diall corparate tollfree conference calls

Please help with case. Issue description is as follows.
1. My Z10 handset and my airtel SIM together - unable to dial conference calls that start with 000 800 ** ****
2. My airtel sim in another handset, works
3. Another SIM in my Z10 Handset works.
Any help is appreciated.

Hey vattokutraj,
Welcome to the BlackBerry Support Community Forums.
Thanks for the question.
This issue can be resolved by your network service provider. I would suggest getting a new SIM card from airtel.
Let me know if you have any more questions.
Cheers.

Why can I no longer connect a conference call?

Since the iOS 7 update, I am unable to connect to a conference call. Is this an ongoing problem?

It is similar to call waiting. The calls are swapped rather than connected.

External callers unable to join conference calls

Scenario: A conference call is set up using the scheduler. Lync users are able to join the conference calls. Users from outside PSTN are unable to join the call. They get to the attendant, and are told they are being joined to the
conference, then get a message "Sorry, I can't seem to connect you to your meeting right now. Goodbye." and the call disconnects.
Looking at call traces, I see the following error messages in the CAAServer log:

The trunks are configured with REFER off and MediaBypass Off.
We have recently moved to a direct SIP trunk from a vendor on Microsoft's Certified list.
Lync version is 2010, with the latest CUs applied. All other calling appears to be working correctly. The certificate on the servers are using the SHA1 algorithm (I have seen some similar issues discussed if this was not the case.)
At this point, I have reached the end of my immediate troubleshooting skills with this system. Can anyone offer any suggestions as to what might be going on here?
Thanks for any help.
-Tim

Hi,
Please check if the default gateway associated to the Mediation Server is up or not.
Please check if Media traffic on the Gateway be blocked with the issue of wrong encryption. Make sure it is using SRTP (not RTP). If you use RTP, please change it and then test again.

Unable to split up conference call on iPhone5

When i am on a conference call and i want to disconnect one of the callers, my only option is to disconnect the conference call all together!!! I called verizon wireless and they said "verizon removed that feature"!!! This is really frustrating and annoying!!!! when are they going to reactivate that feature again???? If nokias or sony ericsons from the 1990's were able to split up a conference call why can't a futuristic iPhone do that??? Also if i am on conference call and want to speak on one of the parties privately, i am unable to do that either!!!

Con esta solución me funcionó PERFECTAMENTE.
Si por alguna razón no podéis descolgar las llamadas:
Sistema->Ajustes->Personalización->Gestionar notificaciones-> Aquí hay un apartado de "inhabilitadas" comprobar que InCallUI esté activada (tick verde)
Ahora ya puedo utilizar el teléfono con normalidad.
Muchas gracias Mr_O por la solución.
This solution worked for me PERFECTLY.
If for some reason you can not pick up the calls:
System-> Settings-> Customization-> Manage notificaciones-> Here is a section of "disabled" check InCallUI is on (green tick)
Now I can use the phone normally.
Mr_O thank you very much for the solution.

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 ,
To make the conference call, click here for information.
The dropped calls, is this the one area?
Do you have any problems with texts?
Thanks.

Conference call not working in IPCCX callcenter environment

hi,
when i make a conference call using "conf" soft key. the initiator hears the busy tone when adding third party.. i am facing the same problem when all extensions are internal numbers...the cucm version is 6.1(4) and ipccx 7.0
Regards
Nareh

If you are unable to perform a conference from your phone than your issue is unrelated to UCCX and is somewhere in your UCM implementation.

Conference calling codes not picked up

I am using a 800 # conference calling service which worked fine on my Droid Thunderbolt. Just upgraded to Samsung Gal III. Now I get in to the service using the 800 number, but the conf calling service does not pick up the conference ID 10 digits and #, just says I dialled an incorrect conference ID number. It jumps to this message even before I complete the code sometimes.
Any setting to enable secondary numbers after connecting to a call?
Thanks.

Hello Armynova,
Thank you for reaching out about this issue. Conference calls are super important in the business world and rest assured that we are dedicated to getting this resolved for you. May I ask what software version do you have on the Galaxy S III? Also, when you press the number key to enter the conference ID, do you hear the DTMF tone? If not then please advise so we can partner together and implement a solution for you.
Thank you…

Droid Incredible won't Conference Call - VZW Area Supposed Known Issue

My Droid Incredible won't connect when you try to add in 2nd call. No one in my area can conference call with their Droids...not even the VZW Store Droid demo models or the reps there who have the Incredible. My friends have tried conference calling with their Droid's with no luck as well. VZW tech says its a known issue, and until Verizon pushes out update to our area - I'm out of luck! The rep said my options are that they can replace my phone with a different phone model or of course I can break my contract. Really? You want me to go to Apple and get your competitor's Iphone?

With the Droid Incredible I do not have the SEND option once I am connected to the first party. I just have the END CALL button on my screen. I just got off the phone with Customer Service who reviewed the Tech support notes and she said according to the Ticket the issue is my area, and the way the Droid's are designed to conference call. The work around in my area is to hit SEND twice to connect the 2nd party, however she did state, as I can observe, that the Droids do not have the option to hit send on a 2nd call. My friend has a Droid X in my area and he too is unable to conference call. According to trouble ticket they cannot do anything for me. I am out of luck and my only option is for VZW to give me a new model phone, well we all know the only comparable phone is the Droid X which won't help me as it can't conference call either. With what I do, I need to be able to conference call and if I pay $300 for a phone with the feature, I expect Verizon to accomodate me so this just boggles my mind why Verizon isn't working hard to address this issue. So the only other alternative I see is to break contract and move to AT&T and get the Iphone, but I really do love my Incredible so this is a hard decision. Why is Verizon not working to address this issue? Who can I talk to???

Did you know that the carrier Verizon offer the merge conference call or internet while on call on the iphone? Only AT

Did you know that you can't use the merge function on a iPhone 4s with Verizon Wireless? They blocked the function only AT&T has it, also Verizon doesn't allow browsing the Internet while on a call like AT&T, huge mistake Verizon. For people that conference call, don't get tricked into changing carriers until Verizon changes this feature.

Not sure about the merging of calls, but being able to browse the internet while on a call can't be done with CDMA technology -- so it's not that Verizon doesn't allow it, it just can't be done on their network. This is old news ...

Why my iPhone wont let me add to conference call or hang up on a particular person?

Welcome to the Apple Support Communities. The following article will go over the Conference features and will provide some help.

If you continue to have issues with the Conference feature, the next step would be to reset settings or backup and restore the device and setup as new. To reset settings on the device: Settings > General > Reset All Settings

HI I have an Iphone 3GS and the microphone jack works when I play music but not when making phone calls. please help as I use it for conference calls

Hi I use my phone for conference calls and use the microphone jack to connect to speakers. It doesnt work when making phone calls but when i play music on the phone the jack works with the external speaker.

Happy to have been of help. Hope all goes smoothly.
BTW, for the sake of others who may help you here, it's usually most polite if you mark the post that answered your question as being the one that "solves" it, not your own post. That's how people get points here, if a questioner marks their post as either "helpful" or "solving". It's not an issue for me, but for those just starting out in the forums it may be important to them. See:

Problems with conference calls(adding and merging calls) after upgrade to ios 8.1.2 on iphone 5s

I am having weird problem intermittently with adding calls or merging them or swapping them. The issue happens 8 out of 10 times whenever I try to do a conference call. This issue came up after I upgraded to 8,1.2. Never experienced this in 8.1.1 or previous version.
Some of the scenarios that I have experienced is:
1. While on the call, when I try to add a new contact, it just doesn't dial the second number.
2. Sometimes the second number gets dialed, cannot merge the calls.
3. After talking to the second person, cannot go back to the first call.
I am very sure that this is not a carrier issue as it worked flawlessly before upgrade.
Anyone experienced this before? Any suggestions?

Thanks for the above infromation. I did a complete restore of my iphone through iTunes connecting it to my computer via cable. iOS8.1.3 was re-installed. I then added back my settings and data which were backed up prior to restoring the phone. I still have the same issue with conferencing and adding a third caller. When I hit the [+] box, the existing caller is not put on hold. The phone appears to be making a call but it is not dialing to the 3rd party. Shortly thereafter, the Merge icon appears but there is no active call to merge with. I have tried this several times using my wife's iPhone and our home phone to set up a 3-way call. I know it is not working because the 3rd phone (our home phone) does not ring. Is this a hardware problem? My wife's iPhone 6 works with no problem and was purchased the same time I purchased my iPhone 6. Probably time for a visit to the Apple Store unless there is another solution.

Conference calls all of a sudden do not work??

We have a Call Manager 5.1 with MGCP controlled gateways. Out of no where our ablility to ad hoc conference call does not work. We connect the calls and no one can hear one another. Any suggestions as to what could be the cause? Any feed back would be great.

Verizon recording cut into my conference call

Verizon recording cut into my conference call and everyone (100 people on the call) heard it. I was listening to the conference with the mute on (*6). My phone rang--which everyone heard--and the Verizon message that goes to the caller came on. Everyone on the conference call stopped talking as verizon said, "The person you are trying to call cannot be reached at this time. Please call later." This went over the conference call twice. Can I prevent this or is it a Verizon glitch?

Whilst I have no idea about Verizon ,I use a similar device in UK receiving cellular over broadband in property and I have wired broadband with unlimited use
However the device is certainly using bandwidth over my wired service when active
I would try to get a definitive does it or doesn't it and if not then they will cover any cost if they are wrong
