Yes, aussie88, I think we're both looking for the same solutions here. However, you had the good sense to setup your system in PBX mode, so you have more options.
I currently only have my test number working. I've asked my carrier to point one of my seldom-used 800-numbers to my trunk group and send in my 10-digit main number( let's call it MAIN) as DNIS. I intend to first enter MAIN on line 814 using PRI->telephone number. I have line 814 appearing on my own extension. I expect my extension to ring when MAIN is called.
After this test, I will move line 814 to a phantom extension. I will then put a Primary Coverage button for the phantom extension on all the real extension who want to answer the main number. When anyone calls the MAIN number, all extension will ring (I hope!).
The bigger question I have is how to get multiple occurrences of MAIN? I intend to enter MAIN onto 4 lines (813-816) assigned to my b-channel group. I will assign lines 814-816 to the phantom extension. I hope that by doing this, every caller to MAIN will wind up ringing all extensions who have the primary cover button for the
phantom.
Now I'm in uncharted waters. I still want individuals to have their own DID number. I intend to add 5 more lines to my b-channel group. Lets say 817-821. Yes, I now have more lines (9) than b-channels (4). I will assign the 5 DID numbers in turn to each of lines 817-821 and then place the appropriate line on the appropriate extension.
I have no idea if the above will work. Any comments from the experts? I'll be trying it as soon as my carrier points some numbers to my PRI trunk group.
I'll be reading this thread as well as my own, so feel free to post responses here. If I see we have traffic on this thread, I'll post a pointer to here on my original thread for historical purposes.
