Call routing based on dialled number

I've a call flow that has several inbound numbers.

I'm looking to treat one of the inbounds slightly differently.

In previous systems I've used I've been able to do a conditional check ie 'If dialled number equals x then do this'

I thought I could do something with the condition node but don't see an obvious way to do it.

I know I can split that one dialled number out and do it's own flow, but would like to avoid that if possible, also need to do it without user interaction so any sort of collect digits type thing is out as well

The other option I though about was populating a temp variable with the dialled number but don't see a way to do that either.

Thanks

Mike
