VOIP problem, VERY weird.?

Question

I have a VOIP phone line. I could perfectly make calls with it.. but am unable to call in. I used my cellphone to call in and I hear the ringing tone, but when i answer with my VOIP phone, I hear the dial tone.. just as if the call never went through.

Anyone know what could be the cause of this problem? Possibly the provider? blocking call ins but not call outs?

Answer 1

These kinds of VoIP problems are typically caused by firewalls blocking crucial "ports" required for VoIP communications.

You need to know what ports your VoiP provider requires for service.

Then, you need to know how to port forward all required ports through your router to the ATA phone adapter box.

If your ATA is a separate box from router, then easiest test to confirm port blocking is to put the ATA in DMZ zone of router.  When in DMZ, no ports are blocked and that will confirm if port blocking is the issue.  Once you confirm that port blocking is the issue, then you just need your VoIP provider to tell you which ports must be open or "port forded" to your ATA box.  Often the VoIP service will have FAQs that explaing which ports must be passed through for best operation.

Answer 5

need more info...

is this a softphone, or a service with an ATA...

with a softphone, you need to ensure the audio settings are set properly, so that incoming calls are handled the way you want them to be...

if you are with a service that uses ANI you can dial 1-866-my-ani-is and verify the number read back to you is the number that you believe to be your number...

if all else fails, contact your VoIP provider, as they will be able to walk you thru a more specific troubleshooting procedure for there service..
