1608IP phone issues across a netgear VPN

[IPOguy]

I am having an issue with 4 1608IP phones connected to a netgear 108 POE switch VIA a Netgear 338 VPN router, data comes thru great when someone calls the call is fine for about 1 minute to 2 minutes then the person on the 1608 starts to breakup, the call from the outside is crystal clear, we are using cable modem on both ends with static IP addresses the release is 7.0.5,there is only 4 phones and 4 laptops on the remote side, I have changed out routers, poe switch, the IP500v2 control unit, still having the issue any help would be greatly appeciated

What firmware is the 338 on?
It is not a very stable router to be honest!


BAZINGA!

I'm not insane, my mother had me tested!

1+ on router firmware. It needs to be on most recent version. That said, we've implemented with FVS338 at several locations with no significant issues (once on most current version!)

 

[IPOguy]

would the firmware on the phone be an issue? I also heard to turn off the direct media path, would that be an option?

 

[tlpeter]

If turning off direct media path works then you have a routing issue but that will only help for phones on the same location.


BAZINGA!

All 4 phones are at the same location

 

[tlpeter]

So are internal calls fine?
The external call must go trough the router no matter if direct media path is checked or unchecked, it has nothing to do with that.
Is there any QOS on the internet line?


BAZINGA!

The internal calls will have the same problem at times, I have setup QOS on the routers the cable doesn't have QOS

>I have setup QOS on the routers the cable doesn't have QOS

When did you set up QoS on the router?

It is possible that, because, you have no EF (realtime) capability on your cable connection, that the provider is dropping packets. Why it takes some time before this starts, I am not sure but it may be to do with burst capability

My wish has come true. I no longer know how to use my telephone.
