Call status register

Hi all!

Some time ago I’m using Asterisk (currently at home to manage
the calls. Nothing yet very complex, just something compiled by me using
the source code from the official site of the project and configuring
the files manually to both Asterisk and DAHDI. For now I’m not using any
GUI, but when I have more time, I plan to try something in the future,
for example, to make a statistic of the calls.

But, thinking about the statistics of the calls, in the last days I was
taking a look at the /var/log/asterisk/cdr-csv/Master.csv file, which I
understand is where the calls are registered. But all seem to have a
“ANSWERED” state, even those receiving a busy tone. This happens with
both internal calls between SIP extension and from SIP to PSTN.

A test I did is putting a Grandstream BT200 on DND mode (Do Not Disturb)
and call it from a softphone. While the softphone receives the message
that the extension is busy, the CDR registered the call as “ANSWERED”.

Not sure if it’s something usually due to the way it is configured the
dialplan or any other configuration issue.

Thanks in advance for your reply.


Unable to create channel of type ‘IAX2′ (cause 20 – Unknown)

I have two asterisk servers connected via iax.

I’m just testing, calling from “home_server” via “clinic_server” but I’m getting an error message:
Call gets through to “clinic_server” but will not call back.

Nat=route ???

Hi, I have a question regarding NAT – I have two Asterisk setups, and a couple of softphones on my laptop to test them. In the first Asterisk I’ve got nat=yes for all SIP phones. The second setup is identical as far as software is concerned, but the server is running on a VPS with one of the larger VPS hosting services.

On this second setup I was able to phone out from my XLite softphone but when I tried phoning in nothing happened, basically because the phone was always UNREACHABLE. It would register fine with Asterisk but then disappear. After nosing around for quite a bit I found a suggestion that I try setting nat=route for the SIP phone, and suddenly it worked both ways.

Another SIP phone on the same laptop connects to the first Asterisk server setup (which runs on a dedicated box with fixed IP, not in VPS) but I notice that every minute or so Asterisk tells me that the phone is unreachable, then a few seconds later it becomes reachable again.

My laptop is currently sitting at home with typical home-Internet configuration (ADSL, Nat, no fixed IP).

I did see something somewhere about the big VPS providers using some form of “hidden” NAT but I don’t know what that could mean.

My question is: Does this difference in behaviour have something to do with the second server running on a VPS – and are there any drawbacks to using nat=route on all client SIP phones?

Best regards
