One sided - They hear me but I can't hear them.....

Hi all,
I have vonage and it works fine. I just recently set it up for my parents. The wireless wrt54g is connected to the time warner cable modem. The vonage adapter is connected to the wireless router. Online is set up to optimize sound, not save bandwidth.
Regardless of who calls who, The other end can always hear correctly, while my parents can NOT hear the other person. Here are results from testyourvoip. Any help or suggestions would be appreciated.

Packet losses outbound are much too high, but that isn't where your problem is. Please run the forum VoIP test and post those results.

What Vonage adapter do they have? Please try plugging it directly into the modem and see if it works that way. What kind of telephone is it? 2.4 GHz cordless phones can cause problems with wireless routers. If that's what they have, see what happens with a corded phone.

One way audio is often caused by the spi firewall built into the wrt54g thinking the incoming stream is some sort of dos attack, and therefore blocks it. The solution is to setup port forwarding on your router for the vonage device. I had to do this and never had a single one way audio issue since. It took a good tech to explain this to me after a couple months of frustration Smile

Thanks webfor. I am looking around the web config for the router now but not seeing anything for port forwarding. Any idea which menu it was under?

Thanks for the reply Steve. Here are the results of the test.
The phone is a 5.8 GHz cordless. The vonage adapter is the d-link VTA-VD.

Steps that can help in fixing the one way is first to eliminate the WRT54G router from setup, Conn the vonage adapter directly to Modem & see if the audio is fine. If still doing same then contact VOANGE technical support or u can login to your webaccount & go to feature --> bandwidth saver & bring that to Medium or Normal.

If direct conn is fine & happens with WRT54G. Try these steps :
1) Login to WRT54G webinterface --> Go to Security tab --> If there is a Seperate option Firewall --> enable or disable then choose disable ( this is how SPI firewall is disabled in Linksys routers ). But I am not sure the Version of WRT54G you have. If u dont fine this option then u can ignore it.

2) Than trying to forward all port by Portforwarding. Go to Application & Gaming tab --> go t0 DMZ sub-tab & setup the ip address of vonage adapter in DMZ -- This will have all ports open.
Most of the time. Setting up a STATIC IP in VONAGE ADAPTER. Outside the N/W range & setting that up in DMZ is one of the best step.

3) This is one Very good option which fix most issues behind Routers. Check the Version Number of your linksys ( Found in the bottom eg: WRT54G v3 ), goto linksys.com & go to support & download the latest firmware. See if the Linksys router u have the latest firmware. If not , contact LINKSYS Tech support to have it upgraded. IF WRT54G has old firmware. Upgrading to latest one is the best fix.

Any issues please reply

Put the Vonage device directly to your cable modem and try again for a few minutes.

Also without the router do the Voip speed test and see if you still get the packet loss. If your packet loss continues with the CABLEMODEm direct you have an issue with the cable service.

What is the make & model number on the Cable Modem?
