[asterisk-users] PRI can receive calls but cannot dial out

Hi,

I'm trying to call out from a SIP extension to an outbound destination via a
PRI E1 (Digium B410P).

Please take a look at the PRI debug below.

Note that I have 3 cables connected and 1 port is free (RED).

in AEL dialplan, I run:

Dial(DAHDI/g2/XXXXXXXXXX);

in the *CLI I see the following:

    -- Requested transfer capability: 0x00 - SPEECH
    -- Called DAHDI/g2/XXXXXXXXXX
    -- Span 4: Channel 0/1 got hangup, cause 18
    -- Hungup 'DAHDI/i4/XXXXXXXXXX-7'
  == Everyone is busy/congested at this time (1:0/0/1)
    -- Auto fallthrough, channel 'SIP/4053-00000089' status is

If I enable PRI debug:

So the fact that there's a timeout (MDL-ERROR) makes me think that
there's some kind of signalling error.

What could it be?

I noticed that my system clock was way off so I sync'ed it via NTP and tried
to place a call out. It failed again but this time the log shows a "T303
timed out":

Note that incoming calls via this PRI work correctly.

[asterisk-users] PRI can receive calls but cannot dial out

Hi!

1) How long does the outdial take? Does the Dial-Command return immediatly?

2) Maybe dial-out is blocked by your carrier? Did you try to open a 
trouble ticket there?

3) What number do you try to call? Did you try some different number? 
Alway the same problem?

You receive ISDN-Cause-Code 18. Not sure though, but I would open a 
troubke ticket at your carrier.

Why don't your span numbers match?  1-4 but you have 3-6 in your .conf.

Have you tried to loop the ports or spans back to another port?

Set two ports for cpe and the other two for net, then crossover cable
to connect cpe to net.  Spans should come up and you should be able to
simulate the telco and test everything out in both directions.

Finally, call Digium and your telco if you are able to do the above
with no problems.

Thanks,
Steve Totaro
