Thanks all.

To sum up the findings of this thread. The W60B Factory Default settings only allow for four simultaneous calls and five phones to be registered.

In order to support eight handsets and eight calls, various settings must be changed either from the web panel or from their respective auto provision settings.

Any firmware updates must be completed with five or fewer handsets registered to the base station, so if you have eight handsets you'll need to register three handsets, allow them to firmware update, deregister them and then register the remaining five phones, allow them to update and then re-register the three phones. It's a slightly convoluted and seemingly poorly documented process but thanks to Complex1 and the support staff at Yealink the solution is working.
