iPhone Cannot pick up calls on wait, Cannot make a second call holding the first call

[MPriya]

I have a really weird problem with my iPhone 5S. (iOS 7.1)

1. When I am on a call, I am not able to pick up a second call that is on wait. I can see the second call, I can hear the beep sounds but as soon as I pick up, the call freezes in 00.00 time, and My first caller is still active, not on hold.

2. When I am on a call, I am not able to make a second call placing the first call on hold. The second call disconnects immediately with 3 beeps.

3. I am able to see the incoming calls on wait, when I am already on a call. I am able to hear the beeps coming in. SO it means the call waiting is on (Tried turning it on/off/on too.) But when I pick up the call, the above problem comes in.

What have I tried to solve this: (None of them helped)

1. I tried a hard reset of my iPhone (Holding Power and Home button)

2. I tried toggling the Call waiting button

3. I tried resetting network settings.

4. I called my Operator for assistance. I am using Airtel, India. They told me to dial this code - *43# . I tried it and it gave me this screen. But the problem is not solved yet.

Is there anybody here who is facing the same issue with your iPhone? I never had this problem with my iPhone 4.

i'm on iPhone 5S iOS 7.1.2 jailbroken.. ever since 7.1.x (and the stupid, smaller, round buttons in the Phone.app) I've been having issues answering a 2nd call/call waiting.. although I can answer the cal, the screen will freeze and I can't do much else.. I don't know if this is a jailbreak issue or not, as I never really used my phone stock (jailbreak4life!).. but I don't see much online about this (yet..) :-/

edit: found the culprit! it's BMUIKit. I disabled this and my problems went away~YayyyyyY!!!!

I've always had problems with call waiting on my iPhone 5 even running iOS 6. I always thought it was user error or a Verizon thing. Like a few days ago I tried to answer an incoming call and it didn't switch off of the call I was in. I ended both in frustration.

... a Verizon thing.

Also, handling conference calls is also more challenging on CDMA iPhones (both 4 and 5 variants) since you can't take one party "private" or hang up on one caller while keeping the other active. You can only hang up on all of them at once.

I miss my ATTWS iPhone sometimes... :sniff:
