IP Phone 7821 doesn't want auto register

[Tibor Marchyn]

Hi,

We have bought few of 7821 phones. Beause we didn't have CUCM 9.1.2 I have upgraded to that version and applied latest device pack which enable me to use this type of phones.

Problem is that phones doesn't autoregister even CUCM is up and running and phones have TFTP address set by DHCP.

When I tried one phone add manually to CUCM, it registers correctly, but I really need auto registering working. Don't know if other phones working, but looks they do.

Auto registering is enabled for DNS 2001 - 2997. and I have last DN around 2121. Others are not created in Directory.

Thanks

thx, for advice, but didn't work. CUCM 9.1.2 told me that table "deviceautoreg" doesn't exist

HI,

Did you reset your service parameters after changing auto-reg protocol for all changes to take effect?

[William Bell]

I haven't looked at these phones yet. I do have one in the lab and can test this when I get back into town. That said, the 7800 series phones leverage the SIP protocol stack. CUCM is provisioned to use SCCP for auto-provisioning (by default). I think you may need to modify your Enterprise Parameters to enable SIP as the auto-provisioning protocol stack.

1. Go to System > Enterprise Parameters
2. Look for the parameter "Auto Registration Phone Protocol".  
3. Set this parameter value to SIP.
4. Make sure you have one of your CUCM nodes set to support auto-registration.
5. The server set to support auto-reg should be the first CUCM in the CM Group enabled for auto-reg.

HTH.
