Hi Jeremy,
There seems to be a problem with the phones configuration. The third party should be set to the BLA AOR(the address of the shared line).
In the trace, the problem is with this Subscribe which never reaches the presence-bla server because it gets looped. The correct Subscribe should have the BLA AOR at the R-URI and in TO header and the phones address in FROM header.

Hi Anca,
Thanks for the quick reply. I wondered a little about the phones, too. Alan sent me a note privately, very tactfully reminding me that I'd sent less phone information than I should have.
The Polycom 650: bootrom.ld version: 3.2.3.0002 sip version: 2.1.2.0078
The Polycom 330: bootrom.lod verion: 3.2.3.0021 sip version: 2.1.2.0049
Both phone.cfgs are attached, as well ngrep traces from reboots. I did two traces, rebooting each phone separately.
Again, I appreciate the help very much. Thanks.
