Try as I might, I cannot seem to get caller ID passed to the external sip gateway

 

This GW happily processes caller id from Asterisk

 

If tried adding param name="caller-id-in-from" value="true" in gw definition, and even

 

<action application="set" data="effective_caller_id_number=07539600000"/> in the dial plan to no avail

 

Can anyone shed some light on this?
