[asterisk-dev] Deprecating sip call-limit

[Pavel Jezek]

I'm glad, that you start this discusion, because I think call limits are 
now implemented in way, that can be source of confusion for people using 
asterisk,
we have now three similar options for configuring:
call-limit, limitonpeer, busylevel, or even dialplan functions like 
GROUP_COUNT() etc...
maybe current trunk contain bug, maybe it's my misuse, but currently 
it's not working good and clearly, see my bugreport
http://bugs.digium.com/view.php?id=11304

some example or inspiration from cisco callmanager, that use only two 
simple options per phone to controll all this limits:
"max calls" to set limit for making calls from or to phone,
"busy triger" to set treshold, for busy indication, when reached
both options doesn't differentiate between incomming/outgoing calls,
but it's just enough, most people want be able to place as many calls as 
they want (max calls), and indicate busy, when they have call (busy 
trigger),
eg. when busy trigger is set to '1' it efectively disable callwaiting on 
phone
I think, it will be really nice, if we have some similar options, for 
configuring call limits in phone definitions, i.e without need to use 
special diaplan logic for this.
