Calls to a Vonage phone are only one way communications, i.e. I am heard by them, but they cannot hear me. This started yesterday, and I've spent ~16 hours trying to solve this, with no help from either carrier, each sending me back to the other : (
I am having the same issue! When I call a Vonage VOIP landline, the other end picks up, can hear me, but I cannot hear them. This only happens with Vonage users, all other wireless carriers (ATT, TMobile, Verizon) and landline (Ooma, Verizon, Comcast) seem to work fine. Here's some good news, and some bad news.
Good News: I am a Network engineer and work closely with Telecom engineers. This is a known issue with the SIP trunking and call hand off between the carriers, most likely on Vonage's side.
Bad News: They will, like you said, probably not solve it until it becomes a bigger problem, or if you get a competent engineer from both carriers on a conference call. From there, you should ask to place a call to a Vonage customer to recreate the issue and have them monitor the incoming and outgoing calls from both sides. They should be able to determine the issue from there. Good luck getting someone from both sides on the phone at the same time!
Good News: A work around for the time being until Vonage and Virgin Mobile get their acts together is to use an app like Google Voice. I found making the call through Google Voice works perfectly. That's because Google Voice uses proxy relay numbers to connect the call. It's free and as easy to use as the normal phone app. Good luck!
No problems except when calling from Virgin Mobile (Sprint Network) to Vonage (VOIP). I need to get engineers from both sides on the phone at the same time, but neither side is willing to cooperate at all.
So sorry for the delayed response. It looks like we'll have to escalate this situation to our Network team. Can you shoot us a private message with your phone number so we can investigate?
