what is the detail process of VG224 register with call manager by SCCP?

[Oak Ridge]

we all know how Cisco IP phone registers with Call Manager.  One of the steps is, IP Phones download config file from TFTP server.

Will Cisco VG224 download a configure file from TFTP server?

I asked this question, is because I don't see the TFTP server ip address is configured in VG224. For IP Phone, it get TFTP server IP address by DHCP option 150. 

[Chris Deren]

No, you build the VG224 as SCCP in CUCM using last 10 digits of the GW's MAC address, and then you configure the GW and point to CUCM via cucm group configuration.  That's all, there are no files being downloaded.

Here's a summary of the template we use for building SCCP VG224s.
