One way voice when call/receive calls to some phone #s

Post by knat »

Hi,

I have an issue with one way voice when calling/receiving calls from some (not all phone numbers).
I can successfully call/receive calls to/from 647-203-xxx6 and have a voice issue with 647-203-xxx5
(almost same phone # just difference in the last digit, same phone company).

I use Linksys PA2T-NA device to call. How this issue could be fixed? Help please...!
