Connect IP Phone 7911g to Grandstream UCM6510

Hi,


We are in possession of some cisco 7911g that we want to connect to a IP-PBX Grandstream UCM6510 based on Asterisk.
We created the TFTP server and added the option on the DHCP. The phone gets the SIP firmware and an IP address but doesn't register with the PBX.

We tried some configuration files that the phone gets with TFTP but it still doesn't register.
We succesfully registered some softphone on the PBX so we think that the problem is within the 7911g configuration

The config is attached


Any Help on this will be highly appreciated.

NOTE:  I have never tried configuring 791x for Asterisk. 

The filename is incorrect.  The correct filename should be:

SEP0021A0D9C36B.cnf.xml

I tried SEP in the first place and it wasn't working so i tried SIP...

Either way doesn't work...

Does the TFTP have any logs to determine if the phone is actually doing anything? 

Is the phone even getting a valid IP address?  If it is, what happens if you put the phone's IP address into a browser?

Yes, the phone get the config from the TFTP and an IP address.

When you get the IP in the browser, you get the cisco page for 7911 with all the configuration of the phone.

This interface doesn't let you modify anything though...

The intention was not to modify using the browser. 

On the first page, Device Information, look at the bottom of the page.  Look at the Time, Timezone and Date.  Are they correct or not? 

Next, go to the left side and click on the Device Logs and then Status Messages. 

Post everything in there here.  I want to see what the phone is doing.

Hi

It seems that the date is wrong...

 

here are what's displayed :

Time and date are wrong because the tags are incorrect. 

<proxy>10.42.69.48</proxy>

Use "USECALLMANAGER".  

Factory-reset the phone and let it download the above-mentioned change to the config.

Hi,

I changed the config (i found some config online and i tried) (see attached)

 

The date seems still wrong though

now the logs show : 

1:43:59p No Trust List Installed 

1:43:59p SEP0021A0D9C36B.cnf.xml 

1:44:00p Error Verifying Config Info

<transportLayerProtocol>4</transportLayerProtocol>

This value may work with CUCM but it does not work for Asterisk.   
It is either 1 for TCP, 2 for UDP and 3 for TLS.  

Make sure NAT and ALG are disabled between the phone and Asterisk.  

Hi,

I changed my configuration with your mentions but it stays in the unprovisionned state.

After a bit of recherches, I found on the html page of the phone (when I type the IP on a browser) that the UCM address 1 is my TFTP instead of my PBX.

My PBX doesn't have a TFTP server integrated so I have the TFTP on my laptop instead...

I tried to change this variable this afternoon but I didn't found any lead...

If you have any tips on how to change this I would love to hear about it

 

Thanks for all your answers by the way !

This is fine (and expected).  I am not worried about that. 

Go back to the Status page and find out if anything has changed.  I am more interested if the SEPmacaddress.cnf.xml file contains tag errors or not.
