| Sorry and thanks for your replies.
I mean a situation where you are away from work, you call your PBX and hang up, and REPLACE the hanset on the cradle. After a short while the Phone rings and you pick it, and you get a dial tone whereby you can make a call.
Different from RGA and or Ringback circuit(where you get a ring sinal), am also yet to try this on Option11 Rls 23 (you dial a code, hang up and that particular set ring- for testing ringing on the sets.
Basically (incase somebody may wonder) may be used by personnel to make calls from their residence/houses when required, may be even int'l calls of course you know that sorts out billing since the Telecom company will now bill the PBX line. |
