You need to develop an enterprise dial plan that eliminates potential overlaps such as this one. Either use e164 dial plan or variable length dial plan (think site codes) or uniform dial plan with extension length longer than 4 digits, i.e. 6, where the DN is last 6 digits of the DID or any other prefix normalized at ingress.

HTH,
