I'm testing with my family member's phones.
When my grandma(Verizon) calls my skype online number (425-440-xxxx), there is ringing animation on the cell phone lcd with no ringing sound for about 2 seconds and just stopped.
When my aunt(AT&T) and my cousin(Verizon) calls my skype online number (425-440-xxxx), it works as it should be.
Also, couple of my customers complained that call just dropped like my grandma's case.
Any age discrimination? Sorry didn't ask my customer's age. 
Any idea?
MJ
