I went trawling through some old mailing list threads and discovered 
that the solution is to use a channel bridge through loopback:

<extension name="inbound_ivr">
   <condition field="destination_number" expression="^inbound_ivr$">
     <action application="answer"/>
     <action application="sleep" data="1000"/>
     <action application="ivr" data="evariste_ivr"/>

<extension name="inbound_ivr_6789540670">
   <condition field="destination_number" expression="^(6789540670)$">
     <action application="bridge" 
data={presence_id=6789540670 at pbx.corp.evaristesys.com}loopback/inbound_ivr"/>

This will link the presence entity 6789540670 at pbx.corp.evaristesys.com 
to the state of the bridge.

A static BLF directory key can then be provisioned on the Polycom and voila!
