I got fop2 successfully connect to the ESL. It's also information updates like when a call comes in or when an extension on a call. However under the Queue button, where it shows agent, it's not reporting the name. It's actually show the agent's uuid that freeswitch is using. There a way to convert the agent uuid to display the name?

my button_custom.cfg file:
[sofia/EXTERNAL-NAT/200]
type=extension
label=Test
extension=200
context=abc.local.pbx.com
originatechannel=sofia/internal/200@abc.local.pbx.com
queuechannel=Test@abc.local.pbx.com

[QUEUE/900@abc.local.pbx.com]
type=queue
label=Queue1
extension=900
context=abc.local.pbx.com

in my /var/log/fop2_debug file - I'm also getting this error:
