Confirmation not necessary. I just found that this bug has already been
reported:

Emne: [Asterisk-Users] Possibly a bug? (Was: Setting up calls through
themanager interface)

Thanks Tony/Olle, you both answered my question. However, now I am wondering
if there might be a bug with Asterisk, or if I am simply misconfiguring
something. This is the scenario:

Taken from extensions.conf (a little simplified):
Exten => 1234,1,Queue(managerqueue)
Exten => 1234,2,Hangup

Then, telnet'ing to asterisk manager interface and issuing the following
commands:

Action: Originate
Context: default
Exten: 5555555
Channel: local/1234
Priority: 1

Now, the phone rings at the agent side and it is being picked up. The other
party answers and the call is set up. This is the output from the console:

============================================================================

============================================================================

So far everything is normal. However (and this is the strange part), after
completing this call, the agent answering the call becomes unavailable. Not
logged out, just unavailable. And so he remains.

Issuing the same actions from the asterisk manager interface again will
result in the call going nowhere (if there's no other agents logged in), or
to another agent, even though the queue has wrapuptime=0 and
strategy=ringall. Even calling directly to the queue extension from an
outside line will result in the same. After a little while, the system
becomes unable to dial out, I get these messages:

============================================================================

============================================================================

Also, after this, asterisk takes very long to stop with the stop now
command, and when it finally exits, it returns memory segmentation error (or
similar, translated to English), in addition to the well-known Yuck: Error
in buffer handling...: Broken pipe 

Can anyone confirm this bug? I should add that originating a call not going
into a queue, but directly to another extension works fine.

Regards,
Bjorn

No, you need to use the "Local" channel type. So as not to confuse
between labels I'll use a different name for the contexts. So in
extensions.conf you might have something like this:

[internal]
exten => _1XXX,1,Dial(SIP/${EXTEN})
exten => _1XXX,2,NoOp(DIALSTATUS=${DIALSTATUS})
exten => _1XXX,3,Hangup

[external]
exten => _X.,1,Dial(SIP/${EXTEN}@provider)
exten => _X.,2,NoOp(DIALSTATUS=${DIALSTATUS})
exten => _X.,3,Hangup

Then if you wanted to dial your internal extension of 1234 and
when answered connect them to the outside number 0123456789,
through the manager API you do the following:

Action: Originate
Channel: Local/1234 at internal
Context: external
Exten: 0123456789
Priority: 1

See http://www.voip-info.org/wiki-Asterisk+Local+channels for more info.

Tony
