Grandstream Fax ATA's and related configurations

Hello,
First, thank you for adding the Grandstream ATA's and more specifically, creating fax specific configurations.

I already owned an HT702 but I did not see a template for it yet, so I bought an HT502.

I figured out how to connect to it and get it to provision.  It was actually interesting since the MAC address it uses to get DHCP addresses is not the same MAC that it uses to register with the provider.  Use the MAC on the box or the Device MAC when creating the device and using advanced provisioner.

I wanted to post this to point out some configuration settings that may not be optimized for faxing.  Since I chose HT502FAX I assumed some thought went into making this fax specific.  I wanted to post my thoughts so they can be review by the 2600 team.

First, I found a website that has some fax specific settings for the HT702.  I suspect a lot of these settings will be similar between all providers.

http://support.t38fax.com/support/solutions/articles/19000008321-grandstream-handytone-702-ht702-

However, one thing I suspect may need to be changed right away is disabling the Call Waiting on the ATA.

Disable-Call-Waiting: Yes
Disable-Call-Waiting-Caller-ID: Yes
Disable-Call-Waiting-Tone: Yes

I placed a call with my ATA and then called the number and heard the call waiting tone.  I suspect this will interrupt faxes.

I wanted to post the article above since it has quite a few more options that may be helpful.

Things like adaptive jitter buffer, and jitter buffer length may be helpful.  I assume the fax specific template is being built out to be as reliable as possible when it comes to sending and receiving faxes and I wanted to help out.  

Also, the 5 or 6, 1-3 page test faxes I have sent so far have worked great.

Thanks!

I actually took another look at the provisioner settings and it looks like most of these settings are supposed to be inherited.

At this point maybe there is an issue with the way Advanced Provisioner is creating the file.  My provisioned device still has call waiting enabled and the jitter buffer is Fixed / Low.

It also appears that the inherited "hook flash: no" is not getting set as well.

I tried manually setting the fields to No instead of inherit and they still do not appear to be working.

"Disable Reminder Ring for On-Hold Call" also does not appear to be getting set.
