IOS dhcp and polycom 501 phone

Anyone familiar with any issues with this setup?

We're having intermittent success with these phones successfully completing the dhcp process. The router shows the addresses as bound but, the phone never reboots/initializes with the address and the address is unpingable.

Also seeing conflicts immediately after pool clearing or router reboot

Alternatively, all works well after some router reboots.
