[asterisk-users] Call Limit with multiple SIP extensions
Hello,
I?m trying to setup the following function fpr a customer and at the
moment I?m pretty stuck...
I have an Asterisk (realtime) system with about 50 SIP Phones. 4 of these
extensions have two SIP accounts behind them, so I call two SIP Accounts
via Dial(SIP/10&SIP/11).
So for example I have the extension 20 which rings the SIP Accounts 20 and
*20 (callerid is setup to 20)
exten => 20,1,Dial(SIP/20&SIP/*20)
This works so far. Now I need something like a call-limit function for
this "special" extension.
When one of the phones (20 or *20) is in use, the complete extension 20
should signal a busy to the next caller.
OK, i found the group function in asterisk and I managed to setup the
first half of the solution.
I use a macro
exten => 20,1,Macro(groupdialout,SIP/20&SIP/*20,20)
[macro-groupdialout]
exten => s,1,Set(GROUP=${ARG2})
exten => s,n,Checkgroup(1)
exten => s,n,NoOP(Active Calls: ${GROUP_COUNT()})
exten => s,n,NoOp(${CHECKGROUPSTATUS})
exten => s,n,GotoIf($["${CHECKGROUPSTATUS}" =
"OVERMAX"]?100:6)
exten => s,n,Dial(${ARG1})
exten => s,100,Hangup(17)
to dial my extensions. This works on the incoming direction. But when I
dial an extension from one of my two phones the other phone is still
ringing. I also want a busy signal in this case.
I tried to increase the groupcounter on outgoing calls via:
exten => 20,1,Set(GROUP=${CALLERIDNUM})
and (to PSTN)
exten => _0X.,1,Set(GROUP=${CALLERIDNUM})
exten => _0X.,n,Dial(SIP/${EXTEN:1}@smartnode)
But I think the problem is that group only affects the channel in use - am
I right?
Maybe someone can give me a hint on how to get this working? Or has
somebody did something like that before?
Thanks Michael

on the Asterisk CLI it looks like this so far:

So in this case it dows not work.
On incoming calls it seems to work...

So when I dial 20 and get a connection, the extension is busy for the next
caller on extension 20.
