Still, I should leave the SIP configuration on the USG off?

Again, I didn't think Vonage did SIP.

Not sure about Vonage today, but in back days they did SIP for sure. The PAP2NA adapter they used to widely deploy is SIP only device.

Brano, how do you know you are not having calls fail to ring the phone? I never knew for years until my mother started babysitting for me a few years back.

My SIP provide has log of all calls on their web site and they also e-mail me every time the call does not get connected or is unanswered. So by receiving these e-mail I know when call does not get through (happened few times when my ISP was down or I had router down).

Brano posted : Currently I have PAP2NA (unlocked Vonage) behind USG200 with SIP_ALG off and I don't have any issues with calls not being received or forwarded to voicemail. I get pretty much every single call and the system works.

What bugs me that sometimes (1 of 10) let's say some calls get dropped in the middle or have echo or noise. After reading many various posts on internet I've decided to ditch PAP2NA that hasn't have FW updated for ages and just ordered the new Cisco replacement SPA112 which has apparently re-written firmware, SIPv2 support and overall all components (i.e. codecs) are updated. It's being shipped now and I'll let you know once I get and install it how it works.

About your particular issue. Try following:
1) Disable all NAT aiding features on the adapter and enable SIP_ALG on router. Make sure you pick the correct port.

alternatively
2) Disable SIP_ALG on router and enable NAT aiding features on your adapter.

Point is don't let both devices try to figure NAT passing at the same time.

P.S: Can't wait for IPv6 to get rid of NAT once and forever!

But this is whack. I'm supposed to simply forward ports 10000-20000 straight to the Vonage unit? All of the time? So no other protocols can use those ports ever? Or if some other protocol tries, it just fails!?

Right now I let ANY traffic targeted to my Vonage unit succeed. But I don't forward any ports. I do have the initial failed call problem. I never have any problem with audio though.

This was one of the reasons why I dumped Vonage and went with CallCentric (and my own OBi100 adapter) CC customer support is unbelievable and OBi is infinitely more flexible - all for 3 times less than Vonage :)

dnoyeB posted : I had a PAP2 but got sick of Vonage's inability to properly accept incoming calls. I figured the PAP2 was bad so I bought a new device. A VDV22-VD. Same problem.

OH, I also have a different Zyxel at this point. I used to have a 2+ and now I have a USG20. Still no love.

Incoming calls get a message of some sore and the phone does not ring. Almost 100% of the time if the caller immediately calls back it will get through.

I don't think Vonage uses SIP do they!?

polarisdb posted : For the heck of it, I ended up setting up a firewall rule allowing incoming WAN traffic on udp port 10000 along with a NAT entry to forward that traffic to my Vonage PAP2 ATA. Since then I have not had any signs of Vonage traffic blocked in my firewall logs and no more Vonage phone calls have been autoforwarded to my cell phone without ringing my Vonage line first.

I have Vonage (PAP2 ATA with a USG 50) with auto-forwarding turned on and a few incoming calls do mysteriously seem to get forwarded to my cell phone. It hasn't really happened often enough for me to investigate further at this point...

I just caught one of these this morning and thought of this thread. Basically, the USG 50 firewall blocked some traffic on UDP port 10000 from Vonage's server in NJ (69.59.252.114) and the call was automatically forwarded to my cell phone without my Vonage line even ringing once.

According to (this support note) from Vonage:

The following ports are needed for INCOMING and OUTGOING Internet communications from and to Vonage devices and servers.

RTP (Voice) Traffic: Ports 10000-20000 UDP. When a call is made, a random port between 10000 and 20000 is used for RTP (Voice) traffic. If any of these ports are blocked, you may experience one way or no audio.

This isn't a huge deal for me, but I suppose a firewall rule and corresponding NAT rule could address the issue...

lacibaci posted : Here is a follow-up:
I dumped Vonage for Callcentric and got OBi100 device (Callcentric doesn't have their own device) Everything works out of the box - no port forwarding necessary. The only setting change I had to make was to enable SIP ALG.

lacibaci posted : A little more information:

This seems to be related to the Vonage's forwarding feature - if network is down Vonage can forward the call to another number.
It looks like when I have this on, Vonage is a little aggressive in determining "network down" and forwards the call almost instantly (I see a couple of dropped packets in ZW log)

However, when I turn the forwarding off, it "tries harder" (more dropped packets in the log) and the call eventually goes through.
Very strange.

For now, I turned the call forwarding off and reset the ZW ALG SIP settings to default.

lacibaci posted : Could anyone running above combination advise about USG config? It seems that periodically the USG blocks the Vonage adapter from receiving calls. All outgoing calls are fine it's just every once in a while incoming ones are blocked. I enabled SIP ALG but it has no effect.
Vonage was working fine with my old ZyWALL 2WG.
