Conference using phone Built in Bridge dropping calls

I have a client that is having an issue using the confrn softkey. Here are the steps that are happening.
User is on a call
User presses confrn button
User diales number
New participant answers the phone
User presses confrn button again
Call gets dropped.
Not sure why this is happening as I have not seen this before. All participents are using g711. and the Built in Bridge option is enabled on the phone.

Really did BIB used to be used for that cause I thought it was.
Yes they do have a software CFB setup and it is still having this issue. They have also discovered that if the press the conf button the second time while the phone is still ringing then it works.

Question regarding the use of Built-in Bridge SIP call setup to recording device

We have an application that uses Built-in Bridge (BiB) to setup a SIP call to our recording application. Recently the topology of our network was changed and for some reason the RTP for the call is not being sent. What appears to be happenning is that the SIP messages are sent from the UCCM and once the call is established we get an end call event.
We are not sure how to troubleshoot our network to determine the root cause. Any pointers will be appreciated.
Thanks.

Hi
Did you ever figure this out? I am having an issue with recording calls to the PSTN from 9971 SIP phones. Station to station calls seem fine, and 7945 phones running SCCP seem fine to the PSTN.
Thanks,
Aaron

Worse Phone I ever had, drops calls on average 20 time a day

I have never experienced a phone that drops calls so many times, 9 times on the last call alone. VERY FRUSTRATING. Does anyone else have the same experience, and can anyone offer suggestions?

What network are you on? Have you contacted them? Have you had your phone checked for a hardware fault?
For what its worth, my iPhone 3GS has never dropped a call on O2 in the two years since I've had it, so maybe yours has a fault.

Phone Time Out Causing Dropped Calls

Hi,
When I'm on talking on the phone for more than a couple minutes the screen times out which causes the call to be dropped during mid-conversation. Is there a setting to prevent this from happening?
Current Settings:
Security Timeout is set for 1 HR
Allow Outgoing Class While Locked - Yes
Current OS: 4.6.1.231

Actually, now I don't think this is related to the screen turning off. In fact the calls aren't being dropped either.
For some reason, during some calls I'll be able to hear the person fine one moment and then not be able to hear them the next while still being connected with them able to hear me.
What can I do to get this fixed?

IPhone 5 drops calls as fast as my confidence in Verizon

I've been a happy Verizon wireless subscriber for roughly the past 7 years. I've always had LG flip phones, and in that time have had perhaps 2 dropped calls. In July 2013, I upgraded to an Apple iPhone 5 16GB in black. As each day passes, and my iPhone 5 drops more and more calls, my regret about the poor choice I made in accepting Verizon's offer to upgrade, exponentially increases.
I live in the same home as I did with all of my LG flip phones that performed flawlessly on the Verizon Network. Never was there a dropped phone call. I transmitted a great deal of data via text and picture messaging with out any significant or frequent slowdowns in speed. I never had problems in the timely receipt of my incoming texts. When I turn on either of my old LG phones and place them next to my Apple iPhone 5, they all match, showing 2 or 3 bars of service and LTE.
Conversely, my regrettable, disappointing, and obviously flawed Apple iPhone 5 does outperform all others when it comes to call dropping dependability. I can count on my iPhone to drop 100% of the incoming and outgoing calls, 100% of the time in my bedroom and in my home office. The rest of my home is about a 70/30 crap shoot in favor of it eventually dropping the call where none were ever dropped in the prior 7 years of my Verizon service using LG phones. People will send me text messages over the span of hours, or a day, and they appear to stack up somewhere until I receive an incoming phone call which pushes all of them through at the same moment as the phone begins to ring. Never had that problem before. People will phone me, and I never hear my phone ring or receive a missed call notification. Hours later my iPhone will suddenly go off with the voice mail notification, all the while between showing 2 or 3 bars of reception when I check the phone wondering why expected calls haven't called me, yet. Short of having to walk outside, trying to have a voice conversation on my iPhone 5 reminds me of the old days, and the family having to get into those awkward "TV viewing positions" and holding old style TV antennas and aluminum foil just to get a favorite station to come in better. Thanks to my Apple iPhone 5, I have to do the same "assume the position" when trying to send any picture or large data files.
No, I do not have a case on, or around my phone.
Yes, I keep my iPhone 5 in the same indoor locations that worked well for LG, and have looked for other "convenient" places to locate them for potentially better reception, with no luck.
I am located in zip code 98663.
The 4G coverage map indicates my location is deep within Verizon's "supposed" coverage area.
I've done the recent IOS 7.0.4 software upgrade, and I think it got worse afterwards, if possible.
All 3 roaming functions are enabled.
I've tested the device in multiple places in and out of the house. It does NOT drop calls outside and data is faster, HOWEVER the iPhone continues to register the same 2 or 3 bars of reception outside as it does inside, including LTE.
I do not power cycle daily, but I do power cycle often.
I have tried resetting the Network Settings in the past.
When others are in my home and are serviced by Sprint and AT&T and others, I can use their non-Apple, non-Verizon, phones, and have ZERO DROPPED CALLS indoors.
I've been told I need one of those $250 network extenders. HAHAHAHA!!! Never had one problem in 7 years in the same house on the Verizon wireless network prior to my poor decision to accept Verizon's upgrade offer. Why, exactly, is it my responsibility to pay $250 to fix a problem that has clearly resulted from either a phone that is lacking in quality that Verizon (ironically?) "upgraded" me to into, a wireless network that is inadequately designed in my area to be compatible with some of the products Verizon sells, or both.
This whole nightmare has severely diminished my confidence in Verizon's commitments to both quality and customer care. I sincerely hope that this plea for help from Verizon will bring an acceptable resolution and restoration of my confidence that Verizon is still willing to defend it's once good reputation, and is the wireless provider that I should be proud to be a member of, for the rest of my life. Hate to jump ship, but if there is no loyalty towards customers, why stay?
Thank you.

KinquanaH_VZw:
Thank you for the reply to my concerns.
I have not had a trouble ticket created over this problem. Since the iPhone 5 continuously drops calls, I have not tried to call *611 from it due to the long hold times. Early on, I made several attempts from my land line to call the 800-922-0204 number for customer service. After holding for up to 20 minutes on different days of the week and at different times of the day and never reaching an agent I became frustrated and chose to live with the problem, realizing that Verizon would be of no help to me. When I finally became disgusted with the call dropping, and related poor reception issues, I decided to research the problem, read what others had experienced, how they coped, what problems they specifically reported, how they communicated their problems, how they were treated by Verizon, and finally what solutions were offered by Verizon, and the ability of those solutions to improve the problem to the satisfaction of the complaining/unhappy customers.
From what I was able to dig up, it appeared that replacing the iPhone was successful in satisfying the customers issues with call dropping less than 10% of the time. Statistically speaking, I felt that replacing one iPhone for another would be a waste of my time. Besides, if I can't get through to customer service on the phone, requesting a replacement is the least of my concerns.
You mention some other things that can affect service:
-Location of tower - Lived in same home for almost 50 years. Unless you moved the tower the day I activated my iPhone and deactivated my LG Chocolate (which received flawless reception in my home). I doubt that is the problem.
-Building structure - Again lived here for almost 50 years. It has not changed since the LG had flawless reception and the iPhone has been less than satisfactory.
-Weather - In the 4 years with the LG Chocolate we had about every type of weather that is typical for this region, and never a problem. In the 6 months I've had the iPhone, the weather here has been pretty consistent and good and there is no noticeable difference to the constant call dropping.
-Tower congestion - Admittedly there were consistent blocks of time Monday-Friday that I did notice the LG slow a bit on data transmission, and attributed it to tower congestion. However, even at minimal usage times, such as 2, or 3, or 4 AM, the iPhone still is quite reliable in it's ability to drop calls and transmit data slowly.
In addition to the above things that can affect service, please keep this in mind, I have friends with smart phones on other networks, specifically Sprint and At&T. When they visit my home, I am quite envious of their reception, even when putting the phones side by side in worst spots in my home, theirs outperform mine in every test I have asked them humor me by doing. Other friends with Verizon smart phones that are not Apple products, receive better phone and data service/reception in my house than I do, but not as good as those with other providers.
From the data I was able to research, customer complaints and resolutions, and comparisons of reception in my home before and after the iPhone and with other providers, I concluded this:
Were I someday able to get through to customer service, I would be willing to jump through the hoops, as I am now, so that you can verify and collect what ever technical data you need regarding this problem.
Ultimately, I would be offered the same choice, or two, as all others having the same problem with their iPhone as I am. Exchange it for another iPhone, which is unsuccessful about 90% of the time, and/or I should purchase at my own expense a network extender. If I, and others, had always had poor reception/service in my home, I would have no problem paying for one. Since the case is the other way around, I decided to be proactive about my feelings on having to purchase one, resulting in my plea for help on the message board.
I do apologize for the length of my message, but I wanted to try to cover all of the potential questions that would be posed to me in an effort to look for causes that would eliminate the iPhone or the signal quality provided by Verizon of any blame.
Anyway, I am happy to have you open a trouble ticket and to answer any questions that anyone needs to ask, and do what needs to be done to find a solution. If you were unable to locate my account through my user name or email address I will provide that information below so that you can get started. If there is anything that involves asking a lot of questions, I suggest it be done via email, as over the phone will probably even frustrate the technician or CSR who has to call me back 20 times to complete the questions due to call dropping.
I sincerely hope that you are able to find a mutually beneficial solution to this problem.
Thank you,

How do I get help resolving persistent dropped calls on my property?

Recently my service has degraded and my calls consistently drop when on my property. Who can help me resolve this problem?

I have called customer support before and they stated they would be sending someone to investigate, but never did, and never replied to my emails to understand why. I have always had dropped calls outside and inside my property. Lately it has gotten worse. I don't have issues in other locations.
If I don't get this resolved, I will end up switching providers to Sprint, which doesn't have connection problems at my location. My previous ticket number with your support was ticket# [removed]. I have an HTC OneM8, my zip code is 92653
Please take urgent action as this is a phone I use for business and the dropped calls from my home are unacceptable.
Thanks for your urgent attention! Gary

NUMEROUS DROPPED CALLS!!!!!!!!!!!

You will note my frustration in this email. I apologize in advance.
I have been experiencing NUMEROUS dropped calls per day, with the problem beginning a couple of months ago, and getting progressively worse. I'm in the metro Detroit area. Has ANYONE else been experiencing this, either in Detroit or nationwide?
Lately, I consider myself LUCKY if I experience a 10 minute phone call with no dropped calls. On some of my worse calls, the thing drops out 5-10 times and I need to keep calling the person back. Sometimes the call doesn't drop, but a situation occurs where I can't hear anything and the other side hears a garbled sound.
I have a STRONG 3G signal. It is NOT a signal strength issue. I have an iPhone 3GS. WHAT'S THE DEAL APPLE/AT&T???
Finally -- I notice that my phone gets bogged down with syslogd from time to time. Could this be a software issue where a runaway process takes the processing power away from the phone call process?
- Eric

Same problem here, and on three brand new iPhone 3GS's.
One I travel with, dropped calls all over the country. One my daughter uses in a large city, all calls drop within 10 minutes, most usually much faster than that. One my other daughter uses in a smaller town, dropped calls also often there.
After much searching I come up with a number of 30 percent seems to be the official number that apple/att consider acceptable for a dropped call rate. Since dropped calls "never" seem to happen to the multi-thousand posts apple coolaid drinkers on this board, I imagine your and my dropped call rate is much higher than the 30 percent.
The only thing I have found that helps somewhat is turning off the 3G feature in settings. When you have a suitable 2G signal, the call is more stable. My one daughter cannot do this because her phone reception is full of static without 3G, so it's either static or dropped calls for her. One would think apple/att would have a solution after two years for this dropped calls problem. The other obvious solution is to return the phone and try another carrier/phone.
FYI - Expect this thread to be deleted after a few days. That seems to happen to dropped calls threads on here. I just commented on one last week, and it was deleted already. Perhaps before the apple coolaid drinkers start bashing me they can suggest a few solutions, if they have any, to the dropped call issue this time.

i suggest using firmware version 1.0.1.1 in the meantime if your problem only started after you upgraded to the latest firmware

Refresh dragProxy in List component built-in drag & drop feature

Hi,
I'm using the built-in drag & drop feature of the List component. Everything works fine except one thing. The itemRenderer I use in my List contains many TextInput that the user can fill. The problem is when I drag an itemRenderer to reorder my list, the dragProxy of the itemRenderer doesn't show the text I enter in the TextInput; it shows the original state of my itemRenderer.
Is there any way to update the dragProxy to reflect the changes made in the itemRenderer ?
Thank you!
Matetnic

If editable=true, the user's changes should be saved to the dataprovider when the drag starts. The dragproxy renders whatever is in the dataprovider item

Droid x - Dropped Calls, Freezing Screen and Now its auto dialing

Just got my Droidx cell phone and at first loved it,but now getting frustrated. Quick 1-2 minute calls are ok anything longer and it is dropping the calls. Also periodically the screen freezes. Now last night it called a friend 30 times during the night, I hadn't called her so not sure why it picked her number. Any thoughts would be helpful.... I can't have a phone that is going drop calls and randomly call my contacts.
PLEASE HELP!

Good Afternoon rxpertmed. I know it can be frustrating when your device is not performing well.
Is your software up to date on your Droid 2 Global? The latest version is: 4.5.629.A956.Verizon.en.US.
http://bit.ly/HNpEQY
If the software is up to date, please try running the device in safe mode to determine if third party apps may be causing the issues.
http://bit.ly/r7xUJM
If the device is still not responding, please complete a hard reset.

I hope this information is helpful.

NYC dropped calls

I drop almost every call while in a cab going uptown from Union Square to the Upper East Side, usually on 1st or 3rd Ave. I've even dropped calls going up 6th, 8th, and the West Side Highway. This has been extremely frustrating.
Apple has switched phones for me and made me get a new SIM card. I have provided ATT with the locations, times, and phone #s of the dropped calls. They have been extremely unhelpful.
I've reset the phone network, restored the phone, switched off 3G all to no avail.
I love the phone but can no longer deal with the issue. I am considering unlocking the phone with a 3rd party software and switching to Tmobile.
Any advice?

I am an outside sales rep in NYC and I think one of the problems is that AT&T does not do a good job going from tower to tower so if you are driving you can easily drop a call when switching towers even though you have a good signal. I also find I loose my phone service with a good signal when i am standing still and wonder if maybe I am between two towers that are fighting for my signal. My phone also locks up after a dropped call and I have to wait awhile before I can call back, drives me crazy.

Dropped calls and no service in my house...why am I even paying a phone bill?

I've been a Verizon customer for probably around 6 or 7 years now. I've had plenty of different devices and was always happy with my phone. A few years ago, service started to get horrible in my house. I would barely get service and my phone would drop calls. I have spent hours over the past 2 years on the phone with reps. Some were very helpful, and some were very frustrating. I have put in service tickets and even changed out my phone to try to get better service. Let me also note that AT&T customers get perfect service inside of my house. I don't even want to hear the excuse that Verizon doesn't guarantee service inside of a building due to building materials. The last time I checked, I didn't rebuild my house in the past few years with new materials. I use my cell phone for business when I'm at home, so it is extremely important that it works inside my house. I put my most recent service ticket in almost 2 weeks ago and there is STILL no resolution. I also won't accept if the only resolution is me buying a network extender.. I'd rather pay an early termination fee and leave before I'd ever spend money on another Verizon device. I have had 2 reps in the past week tell me that they would call me back and I never hear anything. I also have been told that they would resolve it by a certain date, only to find out that now they are saying it's going to stay open until they can figure it out. I rely on my phone for work now more than ever since I recently starting working from home, so how can I accept the fact that I am waiting around and paying for a phone that doesn't work when I need it the most? For all of my trouble, they offered me a $20 credit on my account. I shouldn't even use the word "offered" because I was the one who mentioned that I should be reimbursed for my time. I'm so sick of wasting my time on the phone and I am truly disgusted with Verizon. As a long time customer who has spent thousands of dollars over the year paying for Verizon service, I would expect to be treated much better than this.

I am not in the same boat, Verizon works absolutely everywhere I go and I am super happy with the service. If the service started not working however, and I got no resolve, I would just cancel it and switch providers. No point in paying for service you can't use, especially where you live.

CUCM 8.6 Dropped call transfers involving SIP phones

Hi All,
I am a developer who has been tasked with figuring out why call transfers are being dropped by Cisco CUCM when the original call comes from a SIP phone. This scenario works:
Cisco phone calls another Cisco phone, which transfers the original call to a SIP phone
These scenarios do not work:
SIP phone calls Cisco phone, which transfers the original call to another Cisco phone
SIP phone calls Cisco phone, which transfers the original call to another SIP phone
I have researched the Call Manager traces to the best of my ability, and I see some info in there that could potentially point to the source of the problem. I am just unable to understand what the trace means:
10:23:08.672 |//SIP/SIPCdpc(1,74,2342)/ci=24377698/ccbId=175645/scbId=0/active_CcDisconnReq: ccDisconnReq.onBehalfOf=Media : ccDisconnReq.s.sv=2 : ccDisconnReq.c.cv=47 |1,100,63,1.93259^10.10.10.85^*

I have been wondering whether this could be a codec issue, however the SIP phones we are using are configured with the following codecs:
G711U
G711A
G722
ILBC
GSM
and our SIP software is also set to accept the first codec offered by the remote side. It seems from the SIP client logs that G722 is being used as the codec to communicate with the Cisco phones, but perhaps I'm misinterpreting.
I have attached a CUCM trace of a call from a SIP phone (ext. 491) to a Cisco handset (ext. 170) where the Cisco handset attempts to transfer the call to another SIP phone (ext. 492). The trace snippet shown above is from this log.
I would really appreciate it if someone more experienced with VoIP/SIP/CUCM could take a look and offer any ideas on what the issue might be, and also how we might be able to address it. I can try to provide more info about our CUCM configuration if needed.
Thanks in advance!

Leslie, so here is what I found from the traces....
To understand the difference we need to understand how cucm performs call transfers from a sccp signalling point and a sip signalling point
SCCP
When the transfer key is pressed
1. CUCM sends a CloseReceiveChannel and StopMediaTransmission to the IP phone involved in active media (referenced by the callids)
NB, here CUCM updates the call state on the phone to a call state of 8 which is "Hold"
2.CUCM tells the held party to listen MOH from MOH server
3.CUCM establishes newcall leg with the intended transfered destination..Once this call is connected
4.CUCM receives a new Transfer instruction from the transferring phone to connect the held party
5..CUCM sends a CloseReceiveChannel between the held phone and MOH server (to tear down the media)
6. Next CUCM sends a CloseReceiveChannel and StopMediaTransmission to the transfering party & transfered party to remove Xferring party from call
7. finally CUCM sends OpenReceiveChannel between the original called party and the transfered party..and call is done
For SIP signalling. when the first transfer key is pressed
1. CUCM sends invite (re-invite) with an inactive SDP (a=inactive) to indicate a break in media path
2. CUCM sends a Delayed offer to insert MOH or to resume Media stream
NB: CUCM expects a sendrecv offer with SDP to the DO. (NB:if cucm gets an inactive offer SDP in the 200 OK instead of providing a send-recv offer SDP, the media path remains in an inactive state and causes calls to dropcall will drop),CUCM sends an ACK with sendonly to the 200 OK
3.CUCM establishes newcall leg with the intended transfered destination..Once this call is connected
4.CUCM receives a new Transfer instruction from the transferring phone to connect the held party
5. Next CUCM sends a re-invite with an inactive SDP to indicate a break in media path to MOH (in attempt to complete transfer)
6.Next CUCM sends an inactive SDP to indicate a break in media path between transfering party & transfered party to remove Xferring party from call
7. Next CUCM sends a DO re-invite to connect the transfered party. The far end then sends 200 OK with the required SDP to connect the call
Now having explained all of these, we need to look at where the call is failing for SIP-----SCCP----SIP calls without MTP
lets look at succesful SCCP-----SCCP-----SIP without MTP
Point 4 above

So this is the root cause of the problem. Your SIP phone does not know how to respond to multiple media break between it and the MOH server.
The difference between this and the succesful SCCP-SIP--SCCP, is that the held party was a sccp phone, hence the sip phone only has to process one a=inactive SDP message, where as in the SIP-SCCP-SIP, the help party was sip, so the sip phone has to process two a=inactive SDP messages
Now what is the difference when MTP is involved! A Big difference. MTP stays in the media path. So there is never a break in media and no inactive SDP attribute is sent. The flow looks like below:
for the initial call...The SIP phone sends its media to MTP and likewise the SCCP phone
SIP------Media------MTP------------Media-------SCCP Phone
When the new destination is dialled and transfer is commited,
SIP-------------media----MTP--------media---------MTP
The final invoite sent to connect 492 and 491 has MTP as the IP address to connect Media to.

Wao! That was a long one isnt it...It was fun too.
So now you can look at your sip phones and see if they can accept two inactive sdp messages within the same call. That way you can remove MTP. otherwise you will have MTP involved in every single call involving a sip phone, even if they do not involve transfers

"opportunity is a haughty goddess who waste no time with those who are unprepared"

We used to have great service, now it sucks! Constantly dropping calls, dead areas that have never been dead. Getting fed up and getting no help from Verizon.

This is really getting old, no help from Verizon. Service was great 2 years ago now it sucks, Constantly dropping calls, dead areas where there used to be fine. What is verison doing to help this???

I have an iphone 5s, my husband has a casio, my sister in law has a Samsung, my friends have various phones we are all experiencing the same thing – dropped calls, no service and it is outside as well as inside the house or the car. At our residence and along the drive to work or to the store. I don’t text much or use my data much so I am mostly concerned with the telephone service.
