Would this cause a loop?

If I took my VOIPo number and forwarded to my GrandCentral number, and have my VOIPo line as one of the ones GrandCentral calls, would that cause a loop, or how would VOIPo handle it?

Try at your own risk!

EDIT: what number comes back if GC rings the VoIPo phone?
If CID is different you could route it differently to just ring the phone.
