We have changed centrex dialling such that calls to 101 and 111 will no longer be recognised as centrex dialling.
I.e. if you have three digit local (centrex) dialling, and extensions 111 and 101, we suggest you reassign these internal numbers.
101 and 111 now route to a carrier for non emergency police and HNS direct.
As you know, you cannot use extensions 112 or 999 for internall calling anyway (emergency services numbers).
Sorry for any inconvenience caused.
