Confbridge doesn't allow new member if first member is out

Asterisk Asterisk Dialplan
1

I’m running asterisk 13.17.1 and I have to use dynamic rooms. It seems work ok, however I have a situation, when a first member access confbridge a new room is active, so new members are able to dial and get in the same room, Just dialing a number and then dialing the conference room number. But, if the first member exits, no new members can access the conference room. We listen a message conf-invalid. My confbridge has to allow new members even if first member is out.
Here is my extensions.conf:

[from-TECHMAHINDRA]
exten => 41992,1,NoOp(${CALLERID(num)})
same => n,Goto(conferencia,s,1)

[conferencia]
exten => s,1,Answer()

exten => t,2,Playback(desculpe)
exten => t,3,GotoIf([{TIMEOUT} > 2]?desliga,s,1)
exten => t,4,Goto(conferencia,s,5)

[macro-create_conference]
exten => s,1,Set(__CONFERENCENUM={RAND(9001,9999)}) same => n,GotoIf([{GROUP_COUNT({CONFERENCENUM}@conference)} > 0] ? 1)
same => n,Set(GROUP(conference)={CONFERENCENUM}) same => n,Playback(conf-enteringno) same => n,SayDigits({CONFERENCENUM})
same => n,ConfBridge(${CONFERENCENUM},my_bridge,my_user)

[macro-enter_conference]
exten => s,1,Set(INVALID=0)
same => 2,Read(CONFERENCENUM,conf-getconfno,4)
same => 3,Wait(4)
same => 4,GotoIf([{GROUP_COUNT({CONFERENCENUM}@conference)} == 0] ? 6) same => 5,ConfBridge({CONFERENCENUM},my_bridge,my_user)
same => 6,Set(INVALID=[{INVALID}+1])
same => 7,Playback(conf-invalid)
same => 8,GotoIf([{INVALID} > 2]?desliga,s,1)
same => 9,Goto(2)

[externo]
exten => s,1,Answer()
same => n,Playback(call_externa)
same => n,Hangup()
[desliga]

Here is my confbridge.conf

[my_user]
type=user
music_on_hold_when_empty=yes

[my_menu]

I’d suggest providing the actual console output when this happens so it can be seen what goes on. Your dialplan logic is what ultimately decides this and plays the message, so we have to see what it is actually doing.

Hi @jcolp, here is the output: here are 3 calls, first I entered in the room, so a second member entered, then I left the room (I was the first member) then after leave I tried to get in again, but It didn’t work.

The channel that creates the conference bridge (the first member) has its GROUP for conference set to that of the conference bridge. No other member does. If they leave the GROUP_COUNT value goes to 0. You have dialplan logic that checks the value of GROUP_COUNT and if it is 0, then it plays back conf-invalid. I presume that whenever a channel enters the conference bridge you’d want to set their GROUP for conference to that of the conference bridge.

That’s right. My logic had an intention if a dialed room doesn’t exist, so it goes to invalid. But I’d like to keep the conference available if users leave and enter in the conference later. Is it possible?

I stated in my response what I think you want to do, but ultimately you write the logic so you need to determine under what conditions you expect that to happen - and how to have the logic account for that. It may be as simple as what I said.

I set up this way:
same => 4,GotoIf([{GROUP_COUNT(${CONFERENCENUM}@conference)} == 10] ? 6)

== 10
Now it is perfect! I was lost in my own logic!
Thank you so much @jcolp!
