[asterisk-users] Problems with monitor / mixmonitor stopping if using Local channels

[Julian Lyndon-Smith]

I am trying to record a queue conversation using mixmonitor (or 
monitor). I am using dynamic queue members (not agents) so I cannot use 
the agent recording facility.

Basically, the call recording stops when a local channel is used and the 
user then transfers the call.

I have constructed a simple dialplan that shows the problem.

[from-sip]

exten => Test,1,Answer()
exten => Test,n,Dial(SIP/7708,120,g)
exten => Test,n,Hangup()

exten => 7709,1,Answer()
exten => 7709,n,MixMonitor(jmlstest.gsm)
exten => 7709,n(works),Dial(SIP/7708,120,g)
;exten => 7709,n(broken1),Dial(Local/Test at from-sip)
;exten => 7709,n(broken2),Dial(Local/Test at from-sip/n)
exten => 7709,n,Hangup()

I am starting the mixmonitor on the incoming channel (from a zap line). 
if I use the label (works) then the entire call is recorded even if 7708 
transfers the call to another phone). If I use the label (broken1) 
instead of (works) then the recording is stopped the second 7708 
transfers the call to another phone).

ah ha! I thought. use the "/n" on the local channel.

If I use the label (broken2) then it works (sort of). Mixmonitor keeps 
recording the conversation even if the call is transferred, but there is 
a whole heap of warnings on the CLI:

this keeps going until the call is ended.

Anyone with any clues, or should I raise a bug ?
