Great App. But has a MAJOR flaw

I have been using this App. For 3 years, it is convenient and great to use especially if u r outta USA and wants to make a local call or an international call per say. The MAJOR flaw that I have been facing is that in 25% of the calls I make, the conversation of the caller would repeat itself for multiple times, imagine u r speaking to a friend and this friend is telling u a story, what happens in the
middle of the call is that it would record part of this story and keeps repeating it.. This is so strange.
