Grandstream HT502 problems to get going

Hi all!! I initially posted this on a different forum, but I dont think the other forum has as much traffic as tomshardware does...

The problem is in regards to the location to connect the device.

I have 2 options:

Option 1: ATA device upstream of my pfsense router (between the cablke modem and the pfsense router)

While this option pretty much worked out of the box and required almost NO setup, it has some severe drawbacks that I am not willing to deal with.

First of all, the phone quality is HORRIBLE. I think its because since the ATA device is before the router, I cannot do QoS, and my LAN traffic going to the internet has priority.. For example, if I am on the phone and simply browse the web, I hear distortion on the line and choppiness.. There's also a lot of noise.

Second problem is regarding my internet connection (30Mbps/10Mbps) connection that is restricted to about 15/5... I've done several tests, the ATA device severely throttles the bandwidth. Not acceptable. At the moment I removed the ATA device, the bandwidth went back up to 27-29Mbps..

Other than that, the idea of having this piece of crap ATA device sitting in front of my fancy router and having my whole network rely on it for internet is not pleasant to me.. If it crashes or otherwise cease to function, my whole network loses internet connectivity..


Option 2: HT502 connected on my LAN with its own IP

I haven't been able to do this one yet. While I could manage to connect to the ATA's webpage and configure it as DHCP on WAN, it gets an IP from my router just fine but doesn't register with the provider's VOIP network.

I cannot access the administrative pages. I believe the provider has somehow locked it. The default user password (123) works, but the default administrative (admin) password doesn't.

If I could use it as a LAN device exactly like other printers or networked devices, I could do QoS and hopefully the sound quality would be better..

Other than that, having the ATA device as a LAN device, I would need to find a way to connect the ATA to a network jack (which I only have 2 in the house, one in a room where there;s no phone jack, and another where there's both..) and also connect it to a phone jack to feed the other phones in the house.

So I am left with the following questions:

With the HT502 between the modem and the router, is it normal that the bandwidth be choked that much? The documentation for the HT502 mentions "RJ45 10/100Mbps" for the ports. If true, then I suspect the processor or other component of the HT502 is not keeping up with a 30/10 connection. What are you guys doing with this problem? On other words, can you share your experience and setup?

If you guys are not willing to have a choked internet connection, and are putting the ATA on the LAN side of the router, what are you doing with the only one phone problem??

Anyways, I would appreciate anything so I can get this working.... So frustrating..

Thanks!!

Well it seems that I fixed it..

Yes. the HT502 is CAPPED to 18Mbps to ensure phone quality over network traffic. So this is what I was told from the Mfg customer support.

If you guys are not willing to have a choked internet connection, and are putting the ATA on the LAN side of the router, what are you doing with the only one phone problem??

The most "controllable" way to do is to put the ATA on the LAN side of the router, hence giving the ability to do QoS, and it doesnt interfere with the network connectivity.

Right now its on the LAN side of things. Im fairly happy with this.
