Whenever we use the app SetGroup(groupname) in our dialplan,the ${GROUP_COUNT} will increase 1.
When we hangup,will the ${GROUP_COUNT} can decrease automatic ?

in contrast to the description above, the parameter is not spelled call_limit (with an underscore) but call-limit (with a minus sign)!!!

so use
 call-limit=1
to allow only one incoming or outgoing call on an extension

we had call-limit=1 working on our test box running 1.2.1, once patch 6111 was applied...that has been added to the source and is present in 1.2.4, as far as i can tell.

however, 1.2.4 is broken now, as it is continually setting the device state 1 (not in use). I don't see anything obvious in the source code, but then again, I'm not a programmer by trade.

but, after the patch in bug 6111 was applied, call-limit WAS working properly, and I would be upgrading all of our servers to 1.2.4 if it was working still.

---

EDIT: the fix is to change type=friend to type=peer in sip.conf. All of a sudden, call-limit works again. What else this might affect, I do not know, but hopefully someone with more expertise might.

this was on version 1.2.1, i'm trying 1.2.4 shortly (as soon as it's done compiling)

---

EDIT AGAIN: same on 1.2.4 - type=friend allows any number of calls through, while type=peer works properly with call-limit=1 (or 2, or whatever).

sorry for the dup

I am using 1.2.1 and neither call_limit nor limit works, but incominglimit still seems to work. Perhaps OEJ means that call_limit has been implemented in the 1.3 development tree (representing the upcoming 1.4 stable release).

it seems the sip.conf parser is looking for "limit" rather than "call_limit" in version 1.0.2.4 at least, maybe others.


setting limit=1 in a sip peer, seems to do nothing at all anyway ... sip show peer <peername> shows the call limit always as zero, whatever combinations you seem to use ...

a better solution is to use the current variant of the SetGroup() command .. (which is also dprecated, along with outgoinglimit etc)



as of 1.0.2.4, this seems to work and uses current * functions


exten => _0.,1,Set(GROUP()=SOME_PROVIDER) ;Set Group
exten => _0.,2,GotoIf($${GROUP_COUNT()} > 1 ?103) ;Exceeded the 1 channel we are aloowed with this provider?
exten => _0.,3,dial(sip/8001/${EXTEN}) ; ok, dial out on SIP
exten => _0.,103,dial(${TRUNK}/g1/${EXTEN}/B,30) ; bah, ok then just fall back to our regular ISDN service.

See title: In order for incominglimit to work you also must have a username= entry in your sip.conf.
