Callcentric outgoing caller ID no longer working

My FreePBX server is no longer sending the correct outgoing caller ID.

The installation worked flawlessly until a recent update.

Edited the /etc/sip_general_custom.conf file with

sendrpid = yes
trustrpid = no

I have outgoing routes that define different caller IDs depending on the route.
I connect to Callcentric with a single trunk.

I'm confused as it worked previously without a hitch.
DEBUG say it's still passing the wrong callerID but nothing I change in extensions, trunks or outgoing routes seems to change it from the default caller ID.

Freepbx version 12.0.76.2
Asterisk Version 11.20.0
