[Q] Best experience to make microphone working with VOIP

---

Hi everyone,
While using VOIP other person can't here me. It seems to be due Microphone problem.
It is my first Android device and I have it since one Month so I am not sure what is the best option to fix the problem:
- Try Factory reset and hope it will help
- Buy BT Headset
- replace firmware with Kyrillos and use Voodoo Control
- send phone back and ask to fix it.

other suggestions?

Is it with just one application or all apps? If you used just one app, try some others and see if the problem persists

It's not your microphone that fail here, but it's rather a misconfiguration of your VOIP app. Try keyword NAT and STUN for your search.

A simple test would be to check with a real mobile call wether the mic is working or not.

I tried Skype, MobileVOIP, and couple of other VOIP clients. In all cases the other party can not hear me. The only thing that is working is sound test in Nimbuzz. If I start it and start other VOIP client in parallel then everything is working but the quality is poor. I guess Nimbuzz's voice test is switching on the Microphone or increase it's sensitivity somehow. It is a pity that Nimbuzz does not support my VOIP provider.

Thank you very much! It works! I installed 3CX App and entered STUN server of my VOIP Provider.

Unfortunately I still have problem. The outgoing audio quality is very poor. So other person can not understand me at all. Initially I though that it is due to connection. But this proble is stay several days and same with different SIP Clients. I found post saying that update to CyanogenMod solved this problem. As far as I know the best ROM for SG3 is Kyrillos. My question is: If I change my original ROM to Kyrillos will I be able to use Factory reset and return back to Original ROM without any problems? Somehow I did not find much about this on the net. It is may be due to the fact that nobody want to change back.
