Can't hear person on other end after 16 mins

Yep, their DHCP is indeed broken. They used to have lease times of 24 hrs, which made sense to me, but one day they switched me over to a different subnet (which ****, I had a really easy to remember IP before) and now the IPs have been all over the place. They claim they'll fix it soon... we'll see.

I have Comcast here in Pittsburgh. I guess I will need to contact them.

As promised I am reporting back on long calls I made this past week.

Only one call over 15 minutes had the problem of not hearing the incoming audio after 15 minute. As suggested by janthony using the flash as if connecting to an incoming call and then back, allowed the call to continue.

I had a long talk with an excellent Vonage tech (Prashant). To make a long story short, after making several tests on my bandwidth etc ... the only thing that he could suggest was that I had the RT13P2 after a NetGear router (not directly after the cable modem), AND I did not have the 5060-5061 and 10000-20000 ports opened on the router.
They are now!

My speculation is that when the VoIP network gets loaded it checks to see if ongoing calls are really active, and If it can't reach the phone adapter to check, it shuts down the incoming call.

It will be some time now until I can make another test.

David, thanks for the update. I will try to get into my router settings and see if I can open up the ports. Which router did you open the ports on? Did they mention why anything might have changed over the last couple of weeks?

Same problem here in Houston with Roadrunner.
Same setup also: rt31p2 behind wrt54gs. Incoming
calls are ok. Talked 34 mins. today but outgoing
ones cut off at 16 mins.
Do you open the ports on the rt31p2 or the
wrt54gs and how do I do it? Fairly new to this.
I don't want to put the 54gs behind the 31p2.

The RT31P2 (and probably all Vonage phone adapters) needs use of ports 5060-5061 and 10000-20000 (yes a 10K port range).

So if the RT31P2 is behind a router you need to allow those ports to get through that router. My router in front of the RT is an old NetGear so I can't tell you exactly how to do it. But I will give you an example of how you would program the RT31P2 to forward the ports -- so you can look at the RT settings page.

1) Find out the IP address of the RT. Do this by accessing your RT, look under menu Status/Router. You will see its IP on the 5th like down.

2) To see what you need to do on your other router, look at menu Applications & Gaming. You would put 5060 in the Start column, 5061 in the End column, Both (port types is fine, but only UDP is needed), put the IP you found in step 1 in the IP address column, finally check Enable. On the next line do the same for ports 10000 to 20000.

I hope this helps.

The CSR did not know of anything that has changed. Although he was very knowledgable, he probably is not up on any changes they make to their VoIP routers

As a casual observer with no Vonage problems, it seems a few of you in this thread have your Vonage adapters behind your router. Can I ask why? QoS can't work with that setup. Why not just put your Vonage adapter between the cable modem and your router and then you won't have to port forward about 10,002 ports.

Just making sure I'm not missing something.

Steve:
You are probably missing the possibility that many local networks ( LAN's) are much more complex than just a router (for a computer or two) and a phone adapter. If you are happy with your network then your not missing anything.

There are many reasons for many different network configurations.
That is why there are so many different network products -- routers, bridges, switches, hubs ....

Thanks for the "answer."
