[asterisk-users] Grandstream BLF and Call-limit

I am trying to get BLF working on Grandstream phones with 1.2.27.  I 
actually have it working, but I found a very strange issue and I am 
wondering if anybody knows what the problem is.

Here is the scenario.  If I have 3 phones, A, B and C.  A monitors 
presence of B and C.  Right now, if I call from B to C, B goes solid red 
and C flashes red, which is correct.  If I add call-limit to the sip 
config for those phones, which the Grandstream docs show to do, and I 
then call from B to C.  The presence for B never changes and C just goes 
solid red (even during ringing).  The reverse holds true if I call from 
C to B.  B shows solid red and C doesn't change from green.

Any idea?  If I remove call-limit on the sip.conf entries, it all goes 
back to working fine.  I tried 2, 9 and 99 on the call-limit and they 
all have the same issues.  I can't imagine why call-limit causes hints 
to stop updating correctly.
