Why am I dropping calls on my I phone 5s?

I have dropped more in a week with the 5s the in 2. Years with the 4s.

if it works with headset connected then it's stuck it's a hardware issue

Why am I dropping calls and only get 3G?

I switched to Verizon because my previous provider stopped covering my area. Now I'm having problems with Verizon dropping calls and not having internet at home. Any idea why the service has gotten worse?

@local101,
Thanks for the additional details! I show you're in an extended area and may see the service fluctuate between 3G and 4G. Verizon Wireless radio frequency (RF) engineers and system performance engineers regularly evaluate network coverage and performance to identify locations that may require additional coverage. Based on their analyses and recommendations cell site construction or other improvements are then planned and budgeted accordingly.
Try removing the sim card for a minute or two. Insert and retest. This should help refresh the connection.

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:

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

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

Constantly dropping calls no matter the phone

All Verizon phones constantly drop calls in my house. Signal constantly bounces from 2-4 bars when the phones aren't moving. The only place I can make calls without dropping signal is if I step out in my back yard. How do I put in a ticket or have someone check this out. The problem has been here since I moved in 2 years ago, however it's progressively gotten worse. Phones are HTC Winphone 8x and Samsung Brightside, but family's Droid X2, Iphone 4, Iphone 5, LG showtime, and a couple other basic phones all have same issue.

Hi mtpica112471!
I apologize for the inconvenience because I realize the importance of operable service! Let's look into this. Current zip code? There can challenges present with indoor coverage.
Thanks,

Why is Adobe dropping support for pre 3GS phones?!

I think it's a bad decision to drop support for pre 3GS devices. There are still many out there and if support is dropped we're forced to still use the old PFI to reach the complete audience.
It's clear that OpenGL ES 2 offers a lot more fancy stuff than OpenGL ES 1.5 does, but still, things like GPU_VECTOR or sophisticated blending are perfectly doable with OpenGL ES 1.5.
And if a clean implementation is really not possible, Adobe should at least allow to publish for old devices even if this means that not all optimization techniques can be used.
I develop iPhone apps using different technologies and AIR is attractive for me because I can target with one project a big range of different plattforms. If Adobe drops support for old phones, this advantage is heavily shortened!
What is your opinion on the this development?

Apple have dropped support for pre-3GS because to pull of the features and performance in iOS 4.3 they had to develop just for the ARM7 chip, and not for the ARM6. They probably have a good sense of the number of people that have the older devices, and think it's ok to not update the software on those devices.
The same may be true for Adobe.
I am trying to find out how to make AIR 2.6 and AIR 2.0 live together in Flash CS5. If I work it out I'll let you know.

Drop calls on landline phone

I'm receiving more and more instances of drop calls on my home phone--both cordless and land line phone. Why?
I was told that with fios this wouldn't happen.

Your calls should not be dropping like that. You can reset the ONT box by using the following steps...
Unplug the electrical power cord of your Battery Backup Unit (BBU) from the wall outlet.
Open the battery cabinet on the BBU (you may need a screwdriver to do this).
Disconnect the batter leads and wait 3 min. Reconnect the battery leads.
Put the battery cabinet back on and then plug the power cord back into the wall
This reboots the fiber optic terminal where all your services come in. If you are still having troubles, please send me a private message.

Why do I keep dropping calls

I have a Iphone 4 why after talking for about five min. I loose my call

Why do I keep losing service/dropping calls with every outgoing call it's not my location it happens where ever I am. It will not let me call out even to customer service or 611. It also will go straight to voicemail when someone calls me, but low and behold I cant even call my voicemail. This is ridiculous and has been happening for almost 2 weeks. What if I have an emergency and need to call out or someone is trying to reach me, that's the whole point of my cell phone. Please help I'm very unhappy! I have a galaxy note 2Hi , Thank you for your post. We're happy to help. Were there any changes to your device when this started happening? Do you have your device in Airplane Mode? Please check to see if you're running the most current software version through Settings>About device>Software update>Check for updates. Are you hearing a recording when you try to make a call? Check in Settings>Call settings>Additional settings>Call barring>verfiy that All outgoing calls is unchecked. Also, make sure that your SIM card is inserted correctly and not damaged. We have some additional steps to try. First let's try a Soft Reset by removing your battery for 2-3 minutes. This will re-optimize your device. You may also try running your device in Safe Mode for 2-3 hours: http://bit.ly/1vkcs06 . This will only run stock applications to see if any third party apps are causing this. Let us know if you still need assistance! Thanks, Ema with Samsung Support

Why does my iPhone 4S drop calls with good service

Why when I have 3 or more bars does my iPhone 3S drop calls?

Go to Settings > General > Accessability > Incoming Calls then set to default.

Why does my iphone keep dropping calls

Why does my iphone4 keep dropping calls??? It has been doing it for over a week. Does anyone have an answer.... AT&T says they are not having any problems and I have done everything but restore my phone.

Unfortunately, this has plagued the AT&T iPhone since the original model came out. It's most likely a dead zone causing the issue (I have the sameissue from time to time). You can also get a Micro Cell from AT&T, it's basically just an access point that allows you to pick up a cellular signal at home or work (where ever you set it up).
To eliminate any hardware issues, make sure you're on the latest build of the OS (4.3.3 for the AT&T iPhone 4) - I noticed you're still on 4.3.2. If you don't have a case, I suggest the Apple bumper or any case that covers the metal bezel on your phone, that will help as well.
Also, you can "reboot" your phone. To do this, hold down the metal sleep button on the upper-right corner of your phone until the "slide to power off" slider is displayed, then power off the phone. Wait a few minutes and turn it back on.
Hope this helps!

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.

Why am I getting dropped calls every since I upgraded to IOS 7?

I upgraded to IOS7 and I have been having dropped calls all the time. I talked to Verizon and we went through a number of things to fix it but it did not work. Has anyone else had this problem? If so what have you done.

I know how important service is for you and your wife olehippy52 and I'm sorry you are now having issues at home. I also want to apologize for the experience you had at the store location. The information given to you should have been provided with some investigation and a better explanation. We can look into the area issues especially if you had service before and now have problems. What is your zipcode? What two phones do you and your wife have? You can usually dial *228, send and option #2 to update 3g phones. You can reach out to us here via private message, by phone to talk with tech support, chat, or social media. Once we speak with you, we can get started with an investigation to get this fixed and keep you with our family. We look forward to hearing from you soon.

Dropping calls like crazy..why!!??

I normally have great service at home..but the past few days, I'm dropping calls like crazy..have to go outside and stand in the driveway. NOT convenient! Also I keep losing my wifi when i go to the other end of the house, it starts using my 3G, never had that issue before either. Is there something I can do? Beyond frustrated....

To power cycle device press the power button until you get the slider on screen to power device down.... Once its powered down press the power button again to power device back on.. Also you can press power button and home button to do a hard reboot.
When it is reported to retest your device all you have to do is simply use the device like usual and see if the issue continue.

4.3.2 iPhone upgrade and dropped calls.

Since upgrading to the 4.3.2 OS three days ago, I've been experiencing numerous dropped calls on the order of one every minute. Calls linger in limbo before connecting and then drop. Antena signal reads 3 bars. I'm missing calls too. I live in the same area and have NEVER had a problem with dropped calls until this update and it is really causing problems. Why? Is the phone failing? Is this an update problem? Is this a network problem? Is anyone else experiencing this?

I am experiencing the same issue here in Germany, Network is T-Mobile.
Since upgrade to 4.3.2 I have dropped calls regularly with my iPhone4!!
This is getting more and more annoying.
What happens is: I am starting a call or am receiving a call. The call stays up for 1-5 minutes. During that time (randomly differs from 30 seconds to 5 minutes) all of a sudden the person on the other side does not hear me anymore! I am still able to hear him/her! After around 5-10 seconds after that happening, the connection is lost/cancelled. This is happening independently of the amount of bars, meaning it does not matter whether I am having 5, 3 or just one bar.
Please Apple solve this!! I cannot use my phone anymore the way it is supposed to work! Never had this issue before the upgrade in the same places - in fact, before the upgrade, I did not experience ANY dropped call whatsoever!!
BTW: I tried reboot, reset of all settings, backup, etc. - no positive effect.
