It's not working for which version? latest CVS HEAD?
Can you provide any informations that would help us more on this bug?
At least, please past your ChanIsAvail line.

I too am having the same problem.

I am trying to use this to check the status of my VoicePulse and NuFone IAX connections.

Here are the variables (slightly modified to protect the inocent) in extensions.conf:
TRUNK=SIP/volzsip00-pstn                        ; Trunk interface
TRUNK2=Zap/1                                    ; Trunk interface
TRUNKMSD=1                                      ; MSD digits to strip
IAXTRUNK1=IAX2/voicepulse1
IAXTRUNK2=IAX2/voicepulse2
MYNAME=<My Name>
MYNUMBER=6413429076

Here is my test extensions (exten 7002 doesn't work, _9NXXXXX does work as the ZAP channel is available):
exten => _9NXXXXXX,1,ChanIsAvail(${TRUNK}&${TRUNK2})
exten => _9NXXXXXX,2,Cut(theChannel=AVAILCHAN,,1)
exten => _9NXXXXXX,3,Dial(${theChannel}/${EXTEN:${TRUNKMSD}})
exten => _9NXXXXXX,4,Hangup
exten => _9NXXXXXX,102,Congestion
exten => _9NXXXXXX,103,Hangup
exten => 7002,1,SetCallerID(${MYNUMBER})
exten => 7002,2,SetCIDName(${MYNAME})
exten => 7002,3,ChanIsAvail(${IAXTRUNK1})
exten => 7002,3,Dial(${IAXTRUNK1}/16417845401)
exten => 7002,4,Hangup
exten => 7002,104,ChanIsAvail(${IAXTRUNK2})
exten => 7002,105,Dial(${IAXTRUNK2}/16417845401)
exten => 7002,106,Hangup
exten => 7002,205,Congestion



Here is asterisk remote console logging for exten 7002:
   -- Executing SetCallerID("SIP/volzsip00-1-a129", "<phnumber>") in new stack
   -- Executing SetCIDName("SIP/volzsip00-1-a129", "<My Name>") in new stack

   -- Executing Hangup("SIP/volzsip00-1-a129", "") in new stack
 == Spawn extension (longdistance, h, 1) exited non-zero on 'SIP/volzsip00-1-a129'

Here is the asterisk remote console logging for exten _9NXXXXXX:
   -- Executing ChanIsAvail("SIP/volzsip00-1-d8cc", "SIP/volzsip00-pstn&Zap/1") in new stack
   -- Hungup 'Zap/1-1'

   -- Executing Dial("SIP/volzsip00-1-d8cc", "Zap/1/4144060") in new stack
   -- Called 1/4144060
   -- Zap/1-1 answered SIP/volzsip00-1-d8cc
   -- Hungup 'Zap/1-1'
 == Spawn extension (longdistance, 94144060, 3) exited non-zero on 'SIP/volzsip00-1-d8cc'
   -- Executing Hangup("SIP/volzsip00-1-d8cc", "") in new stack
 == Spawn extension (longdistance, h, 1) exited non-zero on 'SIP/volzsip00-1-d8cc'

I am Running on Suse 9.2 Pro with Kernel 2.6.8-24.13 (Suse provided Asterisk modules have been removed from /lib/modules/2.6.8-24.13-smp/extra/)

Could both of you having the problem apply this patch, recompile, and tell us if you receive any additional output?  This will help us determine which bit of code is not working within ChanIsAvail.

It's not working as of yesterdays CVS HEAD.
Here is an example:
exten => _1416NXXXXXX,1,ChanIsAvail(IAX2/voipjet)
exten => _1416NXXXXXX,2,Dial,IAX2/blah@voipjet/${EXTEN}
exten => _1416NXXXXXX,102,ChanIsAvail(IAX2/NuFone)
exten => _1416NXXXXXX,103,Dial,IAX2/blah@NuFone/${EXTEN}
exten => _1416NXXXXXX,203,ChanIsAvail(IAX2/gafachi)
exten => _1416NXXXXXX,204,Dial,IAX2/blah@gafachi/${EXTEN}
exten => _1416NXXXXXX,304,Congestion

It always returns n+101. Obviously, the IAX channels have corresponding "qualify" statements in iax.conf

Fixed in CVS head.  Thanks.
