Reply to self, missed the line count part. Nevermind then :)

But wouldn't that mean that every customer line is busy every 30 minutes
for a few milliseconds for real callers? Unless there is more than 1
concurrent call enabled on the customers line.

We designed our solution the following way.
We have several land line numbers hooked to an asterisk testing server.
The testing server places one call every X seconds per line to a number
we want to test . We cycle through each number in our testing pool. Each
number on average is tested once every 30 min this can be adjusted by
the dial rate and the number of test lines in the outbound calling pool.
When a call comes from one of our test numbers our inbound dial plans
log the call and busy's out. So the test call is not answered and no
call charge is assessed per carrier. To verify that a test succeeded the
testing server checks the database after it gets a busy. By design if a
call comes in it is checked before any line counts are tested so this
method never effects the customers line counts. We also have a full
audio/dtmf test that is run once a day per number. This means that the
first test call of the day is actually answered and a DTMF and audio
hand shake is done. Both ends log the result in a database.
We catch vendor issues with these methods and it allows us to open
tickets and resolve issues before a customer knows there might be an
issue. Our vendors hate the system as we tend to catch any hiccup they
may be having as well. Several of them are mistified how we can open
tickets on issues consistently before they know they have an issue.

*Subject*: [asterisk-users] checking if a phone number is UP
hi,
We have a phone number from third party provider which is used for
inbound calls. How could I monitor if this phone number is reachable?
the initial idea doesn't sound elegant:
- on my SIP server I set couple seconds of ringing before Answer().
- the monitoring server calls to that phone number for few seconds,
checks if it "hears" the ringing and hangs up the call.
**
I use Nagios to check if my services are UP using check_sip, but it this
situation I'm more concerned about my DID provider than my server. It's
just like pinging a phone number.
Thank you,
Aurimas
