Summary:                    A permanent INVITE that gets BUSY a SIP user
Description: 
I have a queue (with no agents) all of the members using SJphone for
Windows and configured with "call-limit=1".

Sometimes one of them (not always the same user) can't receive calls.

For example, I capture the error now that it's occurring to a SIP username
"lluc-softphone" with extension 209:

-----------------------------------------------------
asterisk*CLI> dial 209
-- Executing [209 at desde-usuarios:1] Dial("OSS/dsp",
"SIP/lluc-softphone|600|wtWT") in new stack
[Jul  3 10:01:22] ERROR[30342]: chan_sip.c:3060 update_call_counter: Call
to peer 'lluc-softphone' rejected due to usage limit of 1
    -- Couldn't call lluc-softphone
  == Everyone is busy/congested at this time (0:0/0/0)
  == Auto fallthrough, channel 'OSS/dsp' status is 'CHANUNAVAIL'
-----------------------------------------------------


But that's not true, in fact:

-----------------------------------------------------
asterisk*CLI> show channels
Channel              Location             State   Application(Data)
0 active channels
0 active call
-----------------------------------------------------


The queue where SJphone users are members is called "interactiva" and the
most strange thing is the following:

-----------------------------------------------------
asterisk*CLI> queue show interactiva
interactiva  has 0 calls (max unlimited) in 'rrmemory' strategy (8s
holdtime), W:0, C:16, A:3, SL:0.0% within 0s
   Members:
      SIP/wadrian-softphone (Not in use) has taken 5 calls (last was 1308
secs ago)
      SIP/lluc-softphone (Busy) has taken no calls yet
      SIP/goni-softphone (Unavailable) has taken no calls yet
      SIP/jose-softphone (Unavailable) has taken no calls yet
      SIP/pep-softphone (Unavailable) has taken 5 calls (last was 331311
secs ago)
      SIP/todiaz-softphone (Not in use) has taken 6 calls (last was 331572
secs ago)
   No Callers
-----------------------------------------------------

As you see SIP/lluc-softphone appears as BUSY.

And more strange:

-----------------------------------------------------
asterisk*CLI> sip show channels

11 active SIP channels
-----------------------------------------------------

As you can see, there is a permanent INVITE SIP channel with the user
"lluc-softphone".


Tshi issue occurs sometimes with differents users, but always SJphone
softphones. Any idea?


If you need more help please ask me and I'll try to get it the next time
it occurs.
