You can do a broadcast hunt configuration on CUCM. You would configure a Line Group that includes the numbers of the users that are in the group. You then configure a Hunt List that points to that group. Then the one number you want to be able to dial would be the hunt pilot. With broadcast, if you call that one number it will simultaneously ring every member of the line group.
No problem. The broadcast hunt in CUCM shouldn't really be a problem. You could also do a shared line where the same DN is configured on all of the phones; however, that may (or may not) be the experience / configuration you want.
OP did not specified if what he want to have all the called parties to be in a conference, or just to talk to the first that answer. In the first case, CUCM does not have a standard feature to do it, reason for which I wrote the script.
Now I understand your post much clearer. Thanks Paolo. Its not my thread so sorry for throwing the +5s around. Hopefully the author of the thread can see if it meets his needs too :-)
