With my Voipo service, callers on the other end of the line hear random beeps throughout a conversation that last a split second and occur on average a few times a minute. On my end, I do not hear beeps but rather short gaps in the caller's voice in place of when they are hearing the "beeps". I have tried different phones (both corded and cordless) and this issue persists. I have Comcast as my ISP and use the Voipo-provided Linksys RT31P2 as my ATA. Has anyone else experienced this problem or have any ideas what could be causing these beeps?
