it is may be not your problem. Problem Belongs to whoom your are talking with. He/She may be useing loude speakers. Or it can be problem of your mobile Service provider. Upgrade your cellphone iOS.

I don't now

You can try adjusting the volume and see if any results. Try to verify if it is a hardware defect by using a Bluetooth piece and if you get better results.

This has no problem to do with the phone as far as i know.
It occurs normally when you are talking to someone who happens to be in a very quite and large room without that it empty. this is due to the empty vaccumm that causes the sound that is produced to be reflected back into themic of the phone and as a result causes you to hear your voice.
Also, another thing that causes it is when you talk to someone who puts the call on loudspeaker and there are multiple surfaces causing the reflection of the sounds you make.
In summary, there is nothing wrong with your phone and you just need to tell whoever you are talking to to try and move to an area that is a bit occupied so as to prevent echoes.

dial *18 talk and after a few seconds call will end automatically,then remove the battery for one full minute...then test it out

It's a common problem with the network. There is nothing you can do but call back the person. Anyone tells you different they are pulling yor leg, my wife and I have Iphones for 3 years now, and sometimes it will happen for a few weeks and then stop. Some phones do it more than others, you can try an upgraded sim card, but if you have everything new I doubt it will help, sorry.

I have a panasonic cordless 5.8ghz I hear an echo when I talk to someone . Can you please tell me how to get rid of it

sounds like maybe you have two microphones running at same time?

try turning the volume down, does it happen all the time?
