T46 hardware versions and multicast paging

[ComResource]

Hello,

We are testing 2 different T46 phones. One is hardware version 28.1.0.128.0.0.0 with firmware 28.73.0.48 (most recent as of this post). The other phone is hardware version 28.2.0.128.0.0.0 with the same firmware. I have the following lines in my provisioning template for multicast paging:

multicast.receive_priority.enable = 1
multicast.receive_priority.priority = 0
multicast.listen_address.1.label = Page All
multicast.listen_address.1.ip_address = 224.0.0.30:10000

When provisioning both phones with this template, the phone with hardware version 28.1.0.128.0.0.0 applies the paging settings successfully. The other phone (hw version 28.2.0.128.0.0.0) will not apply any settings. It is very, very strange. The ONLY difference between these two phones is the hardware version.

I know I could set it manually, but I shouldn't have to. Anyone have any ideas?
