Device updater in OCS 2007 R2 versus update service in OCS 2007 R1

With Device updater in OCS 2007 R2...

You don't need to deal with the web interface to upload and approve updates.

You don't need to install the update server separately.

OCS 2007 R2 device updater doesn't need a sharepoint site anymoe.

You don't need the WINS record anymore (provided the phone device version is equal or above 1.0.522.103).

You need a dns record ucupdates-r2.<DNS domain> for OCS 2007 R2 device updater. The DNS domain should be mentioned in DHCP scope options.

Plug the phone and leave it even without sign in and it will take IP from the DHCP and then asks the DHCP for the Domain name provided in the scope options and after it does that it will go to the DNS and asks for the record ucupdates-r2 under that domain name it received and then it will know from which OCS it should get its updates.

Note: My experience with OCS 2007 R2 Device updater has been fantastic. While it was pathetic to handle OCS 2007 update service.

Do I need WINS record for OCS 2007 R2 Device Updater?

If curent version of OCS phone device is less than 1.0.522.103, you need a WINS record. the hostname is UCUPDATES pointing towards ip address of pool or server. (If its enterprise edition, it should be pool IP Address otherwise it should be OCS standard edition IP Address).

A common cause of problems for the Enterprise version has to do with permissions in the shared updates folder.

When I was working with one of my customers (Ranjan from HCL), I got following error.
