No busy tone on VOIPo

[VOIPoTim]

I had a tree down over the weekend and was at home yesterday making calls to tree contractors. And, they would call me back ... at least a couple of calls when I picked up the phone I would hear nothing. I'd hang up and a few minutes later the phone would ring again and this time all would be well. Does this follow any classic case (no audio / one way audio)? Thought I'd mention this in case this is related to the no-busy signal being discussed.

Do you have all the audio ports forwarded (35000-65000)? It sounds like maybe some port ranges aren't getting through to you and on the 2nd attempt when on a different port it is. If not, I'd recommend trying that to see if it clears this up for you.

No, I have no ports forwarded. I've never had to port forward in the past (with ViaTalk using a PAP2T or SunRocket before ViaTalk) and I have a definite preference not to have to port forward. Surely, if it was an issue with port forwarding, I would have noticed this before?

Support can do some traces to look into it more, but it's possible that the port ranges you're running into have shifted some since we've grown and maybe that's why they're not getting through. Again, no way to know without watching it happen, but 99% of the time the dead air issues are resolved with port forwarding and disabling any ALG so it sounds pretty close.

Russell, you also might try enabling UPnP support on your router, if it's not already.

If port ranges have shifted since I joined, it would explain the behavior. Essentially my setup is as follows: wireless router connected to the cable modem. VOIPo PAP2T connected to the wireless router. I also have an old Vonage RT31P2 connected to the wireless router (I have Gizmo5 and Freedigits - voip service - configured on the RTP31P2). Before my port from ViaTalk was complete, the ViaTalk PAP2T was also connected to the wireless router. And, they all happily co-existed. Of course, now that I'm ported there's no ViaTalk PAP2T and so there's one device less in the mix. The wireless router is an older 3-Com Router that has no ALG ability. uPNP is not enabled - I could enable it if it's felt that that would solve the problem. I have another PAP2T in my toolbox and really would like the ability to connect multiple ATA's behind the wireless router. When I had ViaTalk and the above setup, at one point I had the toolbox PAP2T connected with AOL's now defunct free service and Future Nine (I still have an account with them).
