But Asterisk doesn't send ANY notification regarding change of state (like 
ringing) unless call-limit is 1. In my opinion, ringing status (and probably 
several others) shouldn't take into consideration at what point a device is 
considered as busy.
This worked fine in 1.4 (we skipped 1.6) and seems broken in 1.8. Busy-level is 
1 in both configurations.

After some more investigation, I may have found a clue. When I type sip show 
peer <peer>, the following values are reported:
With DB value 4 or 3 or 2 or 0:
  Call limit   : 0
With DB value 1:
  Call limit   : 2147483647

This doesn't look correct to me...

    Not sure about this since I use the 10/11 branches and not 1.8, but I think 
you need to use the deprecated call-limit for BLF and the new busylimit for the 
other features you need.
    http://www.voip-info.org/wiki/view/Asterisk+config+sip.conf




  Call-limit is the limit on the number of calls you can take and also sets a 
device to BUSY. Since you want to be able to transfer calls, you need at least 
two. But this did not set the phone to busy on one call. That's why we added 
busy-limit that can be set to the level you want device states to signal busy, 
but still give the ability to the phone to set up more calls.


  counteronpeer is the same as limitonpeer, just a new name.

    Subject: [asterisk-users] BLF and call-limit in 1.8

    Hello

    We have recently upgraded our internal PBX from 1.4 to 1.8. This made the 
BLF lamps on our Polycom phones stop working. After a lot of googling and a lot 
of testing, I have been unable to find a solution.

    I did try to change the call-limit value from 4 to 1, and this actually 
made BLF work (noone suggested this, and what documantation I can find states 
that this option is deprecated). This change has other implications, however. 
Call waiting stops working, queues don't offer calls if the user is in a 
private call etc.

    We have customers that require both BLF and call waiting at the same time.


    We are running Asterisk 1.8.11-cert7

    I've made the following additions to sip.conf [general]:
    callcounter=yes
    counteronpeer=yes (undocumented? Supposed to replace limitonpeers?)

    (old relevant values, unchanged)
    allowsubscribe=yes
    subscribecontext=blf
    notifyringing=yes
    notifyhold=yes
    limitonpeers=yes 

    I also tried may other suggestions I've found like placing the hints in the 
same context as the extensions and removing subscribecontext.

    Is there something I'm missing? Is something not working correctly?

    Thanks in advance,
    Pan
