VoIP hardware is developing fast - this is where you ask all those “how do I make my SIP Telephone, Adapter or Asterisk box work with my voip provider?” questions.

The Grandstream GVX3275 factory reset procedure can be found at the bottom of page 105:
http://www.grandstream.com/sites/defaul ... _guide.pdf

Custom dial plan goes here:

So to recap... Factory reset the phones, make sure they are running the latest firmware and set them up as described here:

That should be the phones basic setup done! :-D

The dial plan, 9 for outside looks like it will work. But if I press any key other than 9 I get a message stating the number doesn't match the call plan.
the setup I want is rooms 1-4 are extensions 1-4 8 is reception, which I made a group of 0 with so that if they dial 0 it rings kitchen (5) reception (8) and my mobile and partners phone 6 &7).
but with dial plan I can only dial 9. Does that make sense to you? lol

OK, the following dial plans should suffice...

Reception phone:
Code: Select all
All others:

Re-downloaded and installed freepbx etc.

Whoa, we seem to be jumping from one thing to the next without first resolving the issues at hand...

It looks like you are attempting to register to PJSIP, chan sip and pjsip do NOT use the same ports, they bind to different ports. Why are you trying to setup PJSIP? You still trying to get video calls working? Like I said, you want to concentrate on setting up the six Grandstream phones with the basics before proceeding to do anything else.

Once you have installed FreePBX on your PI, the only thing you should be doing (for now) is updating the modules:

Set "Allow Anonymous Inbound SIP Calls" to "No" and then setup the required extensions for each endpoint:

Once done, configure the Grandstreams* as per these instructions:

Using these dial plans:

I will investigate the dial plan and get back to you, it should work. Can I confirm that you have setup the extensions as single digit numbers? Room 1 = 1, Room 2 = 2 etc.

Once we have the Grandstreams setup correctly, you should then proceed to open up your FreePBX server, secure it and then register your mobiles to their extensions via whatever softphone you have installed on your mobiles.

Final stage is to install and configure the OBi110 and configure FreePBX to use it. You should have everything setup and working at this point, take a backup of your FreePBX image! From this point on, make any additional changes or implement new features as and when required. If you *Bleep* things up, restore the backup and your back up and running in minutes. ;-)

*When registering the Grandstream phones, use the local IP address of your FreePBX server.

Sorry about the jumping thing. I tend to do that lol
I am going to put a fresh install on raspberry. Then wipe all phones to factory now that they have the correct firmware and go through everything slowly, step by step :fearful:

In relation to the dial plan, yes, room 1=1 room 2=2 etc.
8 is reception, because 0 is a call group that contains reception, kitchen, and my mobile etc.
9 is for outside calls.

Still no obi arrived. can take until 25th. complete head melter.

No need to apologise, I can understand and appreciate that you're keen to get it all setup and working.

I thought you already had done a fresh install on the PI, as indicated here? If not, navigate to "FreePBX > Settings > Advanced Settings" and set "SIP Channel Driver" to "chan_sip"

Now navigate to "FreePBX > Applications > Extensions", what's currently showing? sip or pjsip?

If pjsip like shown in the image above, edit each extension by clicking on the pencil under actions:

Then, click on the Advanced tab, scroll down and click on the "Change to CHAN_SIP Driver" button as shown below:

Don't forget to click on the red "Apply Config"button displayed in the top right hand corner of your display.

Your basic FreePBX setup should look something like this: https://1drv.ms/v/s!AusdiKa87-PC9uJfBeZsO8kY1cmKmg
Using the above setup, I managed to register a Snom D715 against extension 8 (Reception) and my iPhone against extension 6 (My Mobile). Now, press 6 on the reception phone and my iPhone rings, press 8 on my mobile and reception rings, press zero on the reception phone and extensions 5, 6, 7 and 8 ring. In the video you can see both the Snom (line 2) and my iPhone ring when pressing 0, that's because I haven't registered any phones to extensions 5 and 7. Video here: https://1drv.ms/v/s!AusdiKa87-PC9uJg32dZrqTZn2xNSw

Like I said, keep it simple and stick to the basics for the time being. :P

Before you give up on it completely, send me the external IP address and admin login credentials via a private message and I shall set it all up for you. Remember to allow outside access to your FreePBX server first otherwise I won't be able to connect to it! :)

Hi Peter, thanks for the private message and for providing me with the login info requested. I'm confused as to why you're still running the Beta? You have also installed every module know to man, including some commercial ones? You should be installing and running this image and only updating existing modules.

If you install the correct RasPBX image onto the SD card and boot up the PI, I will proceed to set it up for you. I'm not going to waste my time (or yours) configuring any alpha or beta images, there are likely still many bugs/issues that need ironing out. As such, those images are still in testing, never use them on a live server! ;-)

FreePBX 13 is rock solid, no reason not to use it! You can easily upgrade to FreePBX 14 once a final, more stable build has been released for the Raspberry PI. :thumbsup:
