Ok the extn is forced to use an account code to be able to make an outgoing call and we have since discovered that this is causing the extn to bypass least cost routing. The LCR is supplying the customer with an itemised bill per extension from the network provider. The extn uses account codes because it's in a classroom used for kids who have been excluded from lessons and can be unattended etc. My question is:

Is anyone aware of a way of forcing the extn through LCR?

If not does later software revisions fix it?

Is there a reasonable work around?
