Initiating a 3-way call

Is it possible to establish a 3-way call from a MIDP 2.0 MIDlet? I'm trying to work out a scenerio that allows a MIDlet to initiate a call, and then once connected to that call, initiate another call (sort of like a conference call). If anyone has tried this type of functionality were there any limitations on it, or gotchas? Also which devices models and/or SDKs might be better suited for this (Motorola, Nokia...etc). Anyones first hand experience would be of great assistance.
TIA
Sue

Well perhaps you won't need support from the telephony operator platform. You must know that i am wandering. If you could achieve to develope some kind of server that can receive phone calls you could make a 3 way-call (but remember that calls in midp are device dependent) ... If you had that server it could mix several phone calls from different sources, example:
You have 3 persons who want to talk each other at the same time. Their phones could make a phone call to your server and it could mix the 3 conversations, while they are talking, into one and return it to each phone device. It would work with whatever number of people.

H.264 doesn't seem to work... until I initiate a 3-way call

Hello,
I seem to have a weird problem with iChat video conferencing. As the post subject indicates--I believe iChat doesn't automatically use H.264 (at least on my configuration) in two-way video calls but does it in multi-way calls, or more specifically after a multi-way call. I discovered it by:
1. initiating a normal 2-way call - video's rather blocky, bandwidth use ~200 both ways
2. adding a 3rd person to the call - video even blockier, still same bandwidth usage
3. removing the 3rd person from the call - video suddenly gets much better (compared to the initial 2-way call, not only to the 3-way call!) with the same bandwidth usage - which makes me think it's H.264 that suddenly gets activated.
I get this with all of my iChat contacts (obviously I had them all check, I was just stunned by the sudden quality increase I got). I'm on a 2.16GHz Core 2 Duo MacBook Pro so it's not a CPU speed issue. The only thing I can think of is that it might be due to the fact that I had migrated my system using Migration Assistant from a 12" PowerBook which might not have been H.264 capable (?) - at any rate I tried trashing iChat's .plists but to no avail.
I'd be very grateful for any ideas...

OK here's what the logs say--not surprisingly, it seems like the MacBook Pro is H.264 capable. What puzzles me is why iChat is looking into a "G4" file but I guess it doesn't matter much if it still finds it OK. I also tried starting a conference etc and having a look at the logs but the sheer amount of data spat out by iChat is rather daunting--is there anything specific I should be looking for?

N95-1 three way calling problem

I had 3 way calling feature before firmware update. After update . I can no loger be able to use that. (eg. while talking with a friend, if I dial the 3rd person, I can join the 2lines by pressing the green call button). After update, pressing call button doesn't join the 2 calls any more. It puts on hold the first call. If I press the call button again, it puts the 2nd person on hold and vice versa.Three of us can never be able to talk to each other at the same time as I used to. I updated the FW again no diffrence. My conference call works. I activated my call waiting. called my network operater and confirmed with them that my call waiting feature still actived. can any one help me?

Hey has anyone split up a 3-way call after initiating it. I had the iphone for AT&T and I would simply tap conference and end call. This is very helpful when you have someone on the phone and get someone else's voice mail. I had american express after waiting for this person, I called the merchant and got their answering machine. I then had to hang-up and was forced to hang up on all parties having to start all over again
I called and they told me after 20 min of research that this is not available with iPhone 4 CDMA. Why not it is on my verizon blackberry so it is not a CDMA thing. It is also available on my iphone for AT&T so it is not a phone thing. Verizon/Apple please explain or at least offer a solution!!!
I think this the first bug with conference calling. See the wired review article:

3-way calling inconsistancies

On occasions when my initial call is a long distance call and I attempt to select my third party call from either my recent call list or my contacts, I hear two beeps and both calls are dropped. The third party call indivdual informs me that the call rings through, but is a dead call. Immediately afterwards I can do a local 3-way call and have no problem connecting my other 2 calls!! I have found the Verizon Network to be lacking in this area.

Hi, Johnsher-
The 3-way calling feature can be an important feature for convenience. The CDMA antenna built into the iPhone for Verizon cannot perform 3-way calls. It would appear the local 3-way calls is a workaround, that is not commonly known of. For more info you can review the user manual online: http://bit.ly/S39FxV. Keep me posted if you have further questions.

Three way calling..... Problems....!!!

The problem is when you merge 2 parties into one; it is either you hear nothing at all from both parties, or you only can talk to 1 person putting the other person on hold. Simply, "merge" just does not work.
I called at&t 10 times to find a solution, still no go.
Talking to a service representatives did not help much. What they do is that they just remove 3 way call feature and put it back on to your account from their at&t system, or they suggest power cycle the phone, or call apple.(duh!) At times, it worked momentarily then voila, the same problem continues.
Then I talked to a tech support, I do not know what it is called but the tech disconnected my iPhone 3g from the network and reconnected it. She said this process is different from partial remove/add features that customer support rep did, it was rather total reset from the network.
Right after the talk with tech support, I was able to connect & merge 3 people (my friends) together that I could not before. Next day, I tried three way calling for the same 3 people but it did not work ever since.
I test called three way call today, calling 611 and Apple iPhone support number 800-694-7400, and it works! However, problem still exists when I try to connect my friends, the same 3 people mentioned above. What gives?
Does the problem have something to do with my friends' carriers? One has T-mo, the other one has Helio, and the third has vonage VOIP home service.
Please let me know.

Three way calls issue

Hello,
I am having difficulty with my phone. First problem. I can make three way calls, but I can't end a call with one person without having to end the call with both individuals. I was on a very important phone call today, long distance, and this really messed me up! Second, when someone calls me, and I put that person on hold to answer another incoming call, when I end the conversation with that incoming call I have to hang up on the other caller on hold!
I have Verizon. Does any one else have this problem??
Please help. It is so frustrating.

Verizon is a CDMA carrier, so your options are limited. This describes (from the iPhone User Manual):

Three way call

Is it possible to drop a caller during a three way call without having to as them to hang up on their own? Is this a limitation of VERIZON's service?

If YOU made the call you should be able to hang up. If someone else made the 3-way connection I wouldnt think so.

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?!

Disable the conference call/ three-way calling function

I have a BlackBerry Bold 9930 - NEED HELP - Is there any way to disable the conference call/ three-way calling function on this phone???? I can't make a normal phone call without randomly starting a three-way call with someone from my contact list or recent call log. I can only keep the phone so far away from my ear!!!! Please help this is a real problem!

Does ‘DM’ mean ‘direct message’ like this email or do I need to send this email somewhere else to reach ‘BobbyS_VZW’. Would like to know before I send my billing password & phone number.

No need to take it there, chelsead13. Throwing it in the river would only make things worst. We can disable 3-way calling. Please follow me (ChaunceyM_VZW) and send me a direct message. Be sure to include your contact number. I look forward to speaking with you.

Problems with 3-way calls, merge calls?

loving my iPhone but having problems with 3-way calling and merging calls. tried to be on one call and have another person call (from a regular land line) and it went straight to voicemail for them. in addition, was on a regular call and tried to add another call AND tried to merge, none of the above has worked. i know this is included in the calling plan.
anyone having similar problems?

Per the Apple note in the link below, "Note: While iPhone is actively transferring data over EDGE—downloading a webpage, for example—you may not be able to receive calls. Incoming calls may go to voicemail."
Perhaps this is what was happening.

Can Firefox Hello be used for three or more way calling or is it only for person to person?

Can Firefox Hello be used for three or more way calling or is it only for person to person?

hello again, i've asked in the development channel for firefox hello about this issue: multiparty video-conferencing is on the long-term roadmap but it might still take a lot of engineering (firefox hello is based on the webrtc standard which is a peer-to-peer protocol between two machines only - multiparty calls might be a rather tricky thing to figure out on this basis)

3 way calling question - NOT SOLVED

I asked this question:
I know how to perform a 3 way call, but what if the 2nd person I called doesn't answer and I get voice mail? I don't want to merge that call.
How do I hang up on the 2nd call placed without hanging up on the original?
And recieved this response:
Three-Way Calling
Merge two calls to set up a three-way call between you and two other parties.
Setting up a Multi-Party Call
1. Establish a call, either by dialing or answering an incoming call.
2. Touch Add Call. The first call is placed on hold, and the Dialer displays.
3. Enter the second phone number, then touch.
If the second person does not answer, press the Sendkey twice to end the connection and go back to the first person.
4. Touch Merge. The two calls are joined into one, 3-way call.
However, there is no Send key once you place a call...only END CALL.
PLEASE TRY AGAIN!!!

I'm a power user in sales on the road all day and it seems EVERY smart phone i get forgets about this "feature" ... it's a necessity!!! And no tech support person ever knows the answer because they're techy and barely talk on the phone much less conference!
When i tested it just now (because i've been trying to figure this out for 3 days), instead of pressing Merge Calls, I hit the Back Arrow and was offered 2 options:
1) Return to Call in Progress (YES!!!!)
2) Access dial pad (not sure why I'd want to do this)
Hope this helps!
Maybe to try a different number (i.e. calling the cell phone instead of the office number you called originally)

When will Apple put a 3-way call on FaceTime?

I have started using my Apple devices more and more now since more of my friends and associates have started to purchase them. I use FaceTime a majority of the time and I feel as though it was missing something. That something was a 3-way call for FaceTime. I want the ability to talk to more than one friend through video chat. If they do end up putting this in one of their next updates or something this will be a big plus for their company. Please listen Apple.

Apple doesn't read this user to user forum technical support forum. There is a way to get multiway video calls: Skype. So until Apple adds this feature there is a workaround. Skype is a generally better solution, because it works with non-Apple products also.

Bandwidth of a 2-way-call through WAN?

Hi Everybody,
I am getting confuse about the codec and bandwidth, wish somebody could help.
By using T1, each channel contains 64Kbps for a 2-way-call, with a G.711 codec
If this 2-way-call is connected through the WAN/internet connection.
Does it consume 64kbps or 128kbps? or it depends on the type of WAN connection type?
Thanks
Sam

Take a look at the Voice Bearer Traffic Provisioning section, esspecially Table 3-10, in the SRND. G.711 at 20ms sampling rate over Ethernet without encryption or RTCP would be 85.6kbps.
Also, remember that you put bandwidth including only down to the Layer 3 overhead in CUCM's Location table while you need to include the Layer 2 overhead in the IOS Modular QoS CLI (MQC) configuration.
Please remember to rate helpful responses and identify helpful or correct answers.
