Caller can't hear me.

I'm having the same exact issue. Incoming caller cannot hear me, or claims my voice sounds very low/far away even though the volume is at its highest. I can hear them perfectly though. They seem to hear me when I put them on speakerphone but cannot pick up every call on speakerphone. Very frustrating. 
* I want to add that I am on an iPhone 6s with Verizon. This problem isn't occurring with colleagues on T Mobile or AT&T. 

Me too. Been going on for a few months now. Lately it's been more of them hearing me but I can't hear them. 2-3 times a day. When they call back it connects. Happened more on my desktop phone than my mobile.

Ok I figured it out...   when I downloaded the app to the smartphone, the app did not ask  to use the microphone.   I deleted the app and reinstalled it.  When I did the microphone permission pop up appeared.  It now works fine.

Callers cannot hear me when they call or when I call.  It happens from the app on my computer and from my phone.  I have adjusted and tried different VOIP settings.  I have adjusted the volume settings.  I have adjusted the microphone settings.  I have uninstalled and reinstalled the app and the phone app.  Nothing has worked.  I am cancelling my account.  This service is terrible.  

bump.  the indicator on the desktop app shows almost no sound level on the mic input.  the computer sees the input fine..  this is on a mac

The caller said they can hear there voice with an echo, but cannot hear me talking to them.

About half of my callers cannot hear me (about 30 calls a day) I have tried using the RC Phone and the RingCentral app and both have the same results. The speaker on my phone is fine, it's a new iphoneX and i am heard very clearly when I'm not using these apps. I have tired reinstalling these apps and the apps have permission to access my microphone. I am literally yelling into my phone and I cannot be heard. Please help before I lose my voice. 

This afternoon I started getting issues with callers not being able to hear me. I can hear them, but for them every other word cuts out. It's not my carrier, my regular call service works perfectly fine. It's only the app. It's not a latency issue, no faults with internet or wifi, and we have no packet loss. I have tried reinstalling, logging out, rebooting devices, you name it. Please help.
