Hi Nick, the script is there, I posted the link above.
The motivation, at least as I've heard it, is that for calls between coworkers, they want to be have a positive indication if the called person is present and busy, as just a ringback could mean either person is absent or not taking the call, and this is not accepted.
To make everything more complicated, customer want to a differentiated treatment, depending if the call in internal or external. I've coded that also in my script.
Many legacy PBX provide this service, and even some PSTNs with differentiated ringback tones.
Paolo is on the money here. The CME system I installed has replaced a Siemens PBX.
The Siemens PBX was able to signal the called when busy, to inform them of a new call waiting and at the same time present a busy tone to the calling party.
The problem I have is that our external customers are used to this arrangement and now with CME they no longer receive the busy tone and apparently are annoyed by the voicemail service.
As I have not played with IVR or TCL so far, I have upgraded to CME7.0.1 and implemented the Octo-line and busy-trigger-per-button solution proposed by Nick.
This works well in that our external customers now receive the expected signal from our PBX. That's the main thing. My internal customers will not receive any notification but I can live with that for now.
Long term I'd like to implement Paolo's script (which pretty much does exactly what I need) or some similar IVR solution.
I'm not able to access my old voice mail messages all of a sudden. The recording says something like 'the message is currently not available'. This has never happened before in all the years I have been using this system. I have t...
