SIP Extensions 'BUSY'

I have extension 100 setup and connected to via SIPDROID on my mobile. I have some classical extensions at 200 & 201 set. I can call these from extension 100 no problem

I have been trying to get callback to work and have setup a sip extension 105 and a incoming route acountname-150 set to callback to my mobile. It works fine when acountname-105@pbxes is called from another sip phone but if I try calling extension 105 from the phone that is extension 100 it does not work and "Busy" is shown in Call Monitor.

Any ideas what might cause this and what I might do to investigate?
