Can someone please help if this set up is possible, the senario is that I have nearly exhausted all of my DID nos and would like to configure the PBX to convert a non DID phone ext. to make an external call. The DN block provided by the local PSTN are from 10xx to 19xx. I would like to configure a phone with an extension outside the DN block to make an outgoing call (for example is Ext 2001). I have an r2mf trunks which prevents a non DID no to dial out. The system is CS 1k, rls.5.0. option 81c. Thanks in advance.
