[asterisk-users] PRI dropouts - solution I hope...

[James Sturges]

Is your dial plan very simple, ie bypass FREEPBX etc, to make sure no
problems.

 

There are also debug command in the CLI:

           pri debug span  Enables PRI debugging on a span

   pri intense debug span  Enables REALLY INTENSE PRI debugging

        pri no debug span  Disables PRI debugging on a span

           pri show debug  Displays current PRI debug settings

            pri show span  Displays PRI Information

 

maybe also set the debug and verbose and see what it says.

 

Is your set the same, is Asterisk between the line and the PBX or just
Asterisk?

 

Have you tried just using Trixbox?

 

Thanks

 

James

My files were almost exactly the same. We only have 10 channels and the clid
signaling was different.

 

We are however still getting the same problems. I moved the box closer to
the optomux (now we have 2m cable from the optomux to the asterisk box.)

 

Any other ideas? We still are having the same problems and also, some
dropouts in the middle of calls.

 

Could the card be faulty ? I purchased it from ebay second hand.

 

PS. What does the "Transfer=yes" do ?

 

Thanks.

Hi, had a few ask for this so thought may be of interest to the list.

 

This is actually for the following setup:

 

Telstra ISDN30 <---------> Asterisk <---------> BP250 PABX

 

The ISDN10, 20, 30's are all the same physical link, but you may need to
change the bchan and dchan settings for ISDN 10 or 20.

 

We have had lot of issues over 12 months, including physical cable issues,
etc.  But this config has passed Telstra test equipment both on site and in
the exchange.  The calls dropping out (for us) are timing issues do to
telling Asterisk to gets it synch from the Telstra line and providing synch
to the PABX.

 

Anyway, Here it is, does not look like much but have had experts working on
it for a while.

 

The system handles 1800 - 2000 calls per day.

 

Thanks

 

James

Recently we cut over to using asterisk (trixbox 1.1.1) for our production
system.

 

We are using a TE110P digium card (Primary rate) with a Telstra onramp 10.

 

Sometimes when people call, on their end it doesn't seem to connect. On our
end, we get caller id, it passes ok to the sip phone but then no-one is
there.

 

Anyone have any similar problems and worked out how to solve it ?

 

Thanks.
