Originate from local channel failing

Asterisk Asterisk Support

Hi,

I’m trying to feed multiple ChanSpy applications into a single MeetMe conference call. I’m trying to link the output of a ChanSpy to the Meetme by originating a call between them, using a local channel. But so far without success. The problem is that I cannot get the originate to work if the channel used in it is a local channel leading to an extension with an application.

A simple testcase is originating from a Playback application to a SIP telephone. The relevant part of the extensions.conf is:

[tel]
exten => 8015,1,Playback(hello-world)

[rec]
exten => 8013,1,DIAL(SIP/8013)

The following CLI command, with verobsity set to 4:

originate local/8015@tel extension 8013@rec

results in 30 seconds of inactivity (that is: no output to the console) and than:

– Executing [8015@tel:1] Playback(“Local/8015@tel-92fa;2”, “demo-instruct”) in new stack
– <Local/8015@tel-92fa;2> Playing ‘demo-instruct.gsm’ (language ‘en’)
== Spawn extension (tel, 8015, 1) exited non-zero on ‘Local/8015@tel-92fa;2’

But it does not dial the 8013 extension.

If I try to use a call-file defining the same connection, it fails in a different way. It now immediately outputs to the console:

– Attempting call on local/8015@tel for 8013@rec:1 (Retry 1)
followed by the messages above, than, after 45 seconds:
NOTICE[18789]: pbx_spool.c:339 attempt_thread: Call failed to go through, reason (3) Remote end Rining
== Spawn extension (tel, 8015, 1) exited non-zero on ‘Local/8015@tel-4b42;2’

I’ve done some experimenting and found that it never works on my installation (Asterisk 1.6.2.5-0ubuntu1) if the channel used in the originate is a local channel leading to an application. I’ve tried the /n switch, but without success.

Solved the problem by moving on to a more recent version of Asterisk (1.8.7). The 1.6.2.5 one was bundled with Ubuntu.

Hello,

Does the ChanSpy originating work? I am trying to do the same you mentioned.

I like to spy on multiple connected Sip channels. E.g.
SIP/1, SIP/2, SIP/3
The audio output of all 3 channels should be thrown into the meetme conference 20000 that can be monitored by another sip client.

What I tried is:
Originate with channel “Local/20000@from-internal” spying on channel “SIP/41,q” quietly

And this seems to work. There is really a new participant in the meetme conference. But I cannot here anything been monitored.
What I’am doing wrong?
I am working on an Asterisk 1.8.9.1 system (Xorcom/Elastix) .

The originating is done by an AMI command as follows:
Action : Originate
Channel: Local/20000@from-internal
Application: ChanSpy
Data: SIP/41,q

The output of the CLI is:

Why can I hear no audio from Sip channel SIP/41 in the meetme converence 20000?

Thank you very much for your help.

Another approach for monitoring a channel could be originating conferences with the help of local channels ( http://www.voip-info.org/wiki/view/Asterisk+local+channels).

SIP/1 ----> is connected with conference 20001
SIP/2 (Monitoring channel) -----> is connected with monitoring conference 20002

Now originate conferences 20001 with 20002 by an AMI or CLI command e.g.:
Action: Originate
Channel: Local/20000@from-internal
Extension: 20001

after that we are muting the monitoring conference local channel, so that it can not be heard in the 20001 conference.
On CLI this can be accomplished with: meetme mute 20001 <userId of the 20000 local channel>

Now we can connect multiple conferences with the monitoring conference and so “spying” or monitoring the dedicated channels.
Nicer would be if ChanSpy would support such a feature.

I try to post further cognitions, because I have no experiences yet regarding performance or other behaviours.
