Problem Registering GrandStream BT-200 in Trixbox CE v2.6.1

Hi,
I’ve recently purchased 4 GrandStream BT-200, and am having trouble getting the phone to register with my Trixbox.
I have set up an extension in Trixbox for the machine and can see it in the Endpoint Manager if I specify the IP address shown on the phone’s display and in the phone’s webadmin interface.
However, the phone fails to show up on my network in the PBX System Status page, and the Status page of the phone’s webadmin indicates that the phone is not registered.
I suspect that I have not configured the phone’s webadmin properly to work with my system, but the phone’s documentation is not much help, and I have not been able to figure it out from any of the many GrandStream related posts on the forum.
I have uploaded screenshots of the pages of the phone’s webmin at the following locations.

If anyone could tell me which settings I need to revise, it would be a great help to a pointy-haired boss like me.

Since you said you are using trixbox. Have you checked the trixbox.org GrandStream forums? Yes I see you also posted there but did you search and read some of them? Three are a few posts talking about how to configure them.

Hi,

Thanks for the referral to the Grandstream forum posts. I have looked at the numerous posts there regarding how to configure Grandstream products. Unfortunately, the consensus seems to be to use their config generator tool, and since this doesn’t run on a Mac platform, and trying to set it up on an Ubuntu problem has taken more than 8 hours of my time without getting the tool set up, it seems they don’t have a very user friendly solution.

I have been in touch with Grandstream support (after a few tries) but their advice has been minimal to the point of not being helpful. It seems that VOIP may not be a consumer-ready solution in this format just yet.

The strange part about this issue is that after trying to configure the phone, and setting up the extension, the phone can be seen in the endpoint manager. It will even leave a voicemail message when I try unsuccessfully to reach that extension. However, I still cannot call into or out of the extension set up for the Grandstream phone.

I’m guessing that the settings in the Grandstream configuration are still not right for my network here, so I would be grateful for any advice on what those settings should be.

Thanks,

I would be surprised if more than one or two people here believed that ANY PBX software could be considered ‘consumer-ready’. I just spent a couple of weeks reading a 800 page manual on a Nortel BCM-50. That’s 800 pages for a single product with a single, proprietary interface and it still fails to adequately cover all of the material needed to setup and deploy this one Nortel appliance effectively. If you know enough to install and support one of these products then you can expect to make somewhere between $50k and $75k/year. Extrapolate a bit and remember that Asterisk has infinitely more option and is a constantly moving/improving target. If a company has to pay someone $75k/year to install and maintain this proprietary appliance then imagine what can be expected from a constantly moving target like Asterisk?

If Asterisk/FreePBX/ ever becomes ‘consumer-ready’ then it is because development has ceased, bug-fixes are the only thing we care about and Asterisk was replaced by something better. Until then I think we’re riding on the edge of the wild frontier, while exciting, will never be a ‘consumer-ready’ place to be. :slight_smile:

A group of us wrote an Endpoint Configuration Manager for FreePBX. It installs as a FreePBX module that you manually install. It requires a TFTP server be running on the same server as FreePBX is, and your DHCP server should give the FreePBX box as Option 66.

You can download it at:

Enjoy and send us your feedback. We plan to improve it.

You sure said a mouthful. It seems almost sacrilegious to mention that it requires a bit of studying and thinking to configure an Open Source phone system with a mix of endpoints.

You have to have a good handle on networking, moderate linux skills and understand Asterisk. FreePBX is a huge administrative convenience but it does not supplant the need to know Asterisk.

If you are going to do this for a living it takes every bit as much commitment as a Nortel BCM cert or Cisco UCM. I have a softspot for someone trying to figure this out for themselves and an equally hard spot for the unqualified resellers and integrators.

Thanks for voicing an excellent opinion.
