Hi, i have a situation where i need some phones to ring on incoming calls for a while, and if there's no answer - more phones would ring. I've figured i could create 2 ring groups. Group 1 - ext. 101, 102, 103. Group 2 - ext. 101, 102, 103, 104, 105. If no one would answer incoming call to group1 in 10 seconds, it would redirect this call to group2. First problem was that i need to see ring group name in front of caller id, as we have a couple of external numbers and want to know which one was in use. So it would stack groups after jumping to group2 : group2:group1:caller id. Could name second group as "." or something similar, so it would not bother anyone. Second problem - as both 101, 102 and 103 belong to both groups, phones would show 2 missed calls for them(if that call was not answered at all) instead of one - one for group1:caller id and second for group2:group1:caller id. We used to have similar thing configured in old pstn pbx. 104 and 105 were configured to flash for the first 10 seconds on all incoming calls and ring only after that. Can it be achieved in a different way? Using 3cx V11 sp4 and cisco spa504g phones. Thank you!
