Outgoing do not work

Sometimes the operator cannot make an outgoing call, in the logs I see this message

Please tell me what is happening, why can’t I make a call the first time?

Without the timestamps that you would get by using the real log files, rather than a screen scrape, and without the verbose 3+ dialplan traces for the whole call, it isn’t really going to be possible even say which party cleared the call.

I’m pretty sure we are also going to need the output from “sip set debug on”.

There is nothing in your log that distinguishes this call from a successful one, that I can see.

You can also get ‘timestamped output’ by appending ‘-T’ to the command you use to start an Asterisk console like:

sudo /usr/sbin/asterisk -d -d -d -d -d -d -r -v -v -v -v -v -v -T

Once the console is started, you can enable SIP debugging.

Note that the timestamping is limited to the current session, but the SIP debugging will need to be disabled after you have collected relevant output.
