got my 4510L mifi two weeks ago and love it so far. I don't use cell phones much, but with the 4510L and a pc or other internet device, I can make and receive VOIP calls over the 4510L. That is until yesterday, seem port 5060 for voip has become blocked??? I'm using textfree w/voice and I'm getting an error "Still connecting to voice network.......try another wifi access"
I did and it works there, so it must be Verizon's network??? Funny, seem to work find for my two week trail period.
Anyone know if port 5060 is blocked and how to unblock it??????
I can confirm they are blocking 5060 UDP.
Called them to complain and they said they are blocking it for 'security reasons'. Yet, they allow 5060 TCP.
This is crap. Open up 5060 UDP Verizon!
