Mobotix and Grandstream

[thewireguys 3]

I just got the Grandstream GXV3140 to test out with my Q24. Does anyone have any how-to's to set them up directly without a PBX? Also any good VOIP system info would be great.

Haven't done much direct SIP calling without a PBX, but shouldn't be very difficult, the Grandstream phone I have setup before didn't need much besides a valid IP to receive a call directly on the same LAN.

 

I would recommend setting up a PBX though. 3CX has a free one for windows that should be enough to setup a test system, I think it will provision the Grandstream for you.

I would like to know how those two work together, its tempting to spend the money on a Mobotix because of using them with a video phone like that.

Yea I just downloaded that software. I just have to find the time to play with it. I can do a direct IP with the the camera but from what I understand I should be able to pick up the phone and call the phone with an extension number or have the camera call the phone on event. I was reading that the T24 auto configures the Grandstreams without a PBX but they just don't show your how to do it manually.

Here's the manual configuration I've used to talk between the GXV3140 and Q24's or whatever:

 

On the camera, Admin Menu > Audio and Phone - make sure Microphone and Speaker are both enabled.

Under VOIP Settings

Setup Mode to Expert

VOIP - Enabled

Hangup on Outgoing Calls - Disabled

SIP Settings:

Username - 3 digit extension

SIP Domain - IP of this camera

Registrar - Leave blank

SIP ID - Enter the User Name from above (extension nbr)

SIP Password - Blank

Use Outbound Proxy - Disabled

Registration Expires - Set to max

Network Settings:

Use Router Address - Disabled

Router Address - blank

SIP Port - 5060

Audio RTP Port - 7078

Video RTP Port - 9078

Audio Data Timeout - Never

Audio Messge Settings:

Set all to Enabled except Delay before Welcome Message. Set it to Disabled.

Audio Codec Settings:

PCMA and PCMU both checked

Video Codec Settings:

Video - Enabled

Video Size - QCIF

Video Bit Rate 150kbits/s

Everything else on this page leave at default values.

Remember to hit the SET button and Close to store into flash.

 

Go back to Admin>Audio and Phone and select Phone Call-In Settings.

Phone Call-In - VOIP

Accepted Phone Numbers or SIP - Blank

Welcome Message - Choose what you want

PIN Code - Blank

Audio Mode - Intercom

Intercom Settings - Threshold and duration to Medium

Hang up call After - Never

Email Profile and Dial-out Profiles - Disabled

Dial-out Idle Time - Leave at Default (has no affect)

Click Set and then Close.

 

Go back to Admin>Audio and Phone and select Phone Profiles.

Click Add New Profile

Profile - Give it a name i.e. FrontDoor

Phone Number or SIP Address - Use the 3 digit extension you set up under the VOIP Settings above and the URL of the camera ( 100@192.168.1.50)

Dial Attemps and Time-out - your preference

Connection Type - SIP Video

Message Name - Choose one of the standard Mobotix messages.

Confirm Call with PIN - blank

After Message has been Sent - Intercom

Click the SET button.

Once the Profile has been applied, you'll see your profile at the top of the page with a TEST button. Click TEST to check all your parameters. When done, Click the CLOSE button to save to Flash.

 

Configure the Grandstream

To configure the phone, you have to access it via the Web interface from another computer on the network. The default username and password are admin.

 

Choose the Account to be configured and select General Settings.

Account Active - Yes

Account Name - Choose a name

SIP Server - enter the IP of the camera

SIP User ID - enter the extension number you set in the camera's VOIP settings.

Name Field - blank

User ID is Phone Number - Yes

Save your configuration

Under the the SIP Settings for the Account choose the preferred Vocoders to PCMU and PCMA. Note PCMU is used in North America and Japan, PCMA in Europe.

Preferred Video Codec - H263 Note - If the H264 Codec is the only one listed, go the Grandstream site and download the latest firmware to get H263. I've gotten a couple of "new" phones that didn't have the latest and greatest and the Mobotix wouldn't work properly until I did the upgrade.

Save your configuration.

 

You should be able to hold two-way conversations between your camera and phone with the camera's video on the phone's screen. You can use the Direct IP application in the phone or set up a speed dial with the camera's 3 digit name.

 

We've used this setup at two different customer's sites but realize that this was set up as LAN operation only.

 

Hope it helps, thewireguys.

works great!! thank you " title="Applause" /> How do you get the camera to go full screen on the Grandstream?

[Harrar 0]

Never had a problem with screen size. Whenever a connection was made to the phone it was always full size on the screen. What other data is on the screen or is it just a smaller size?

 

You may want to try changing the Admin Menu > Audio and Phone > VOIP Settings > Video Codec Settings > Video Size to TV-CIF (352x288) instead of QCIF (176x144).

It has 2 windows on for the q24 and the other for the phones camera. I can turn off the camera on the phone but the box is still there.

Possible Grandstream may have made some changes to their firmware that affects the display. The last time I upgraded was 11 months ago when they were installed. The firmware version I'm using is 1.0.3.X series.

I just upgraded to the latest last night and it still doesn't go full screen. I am going to give them a call today.
