[asterisk-users] Problem with Sangoma A104 and euroisdn pri

Hi all,

My problem boils down to these errors:

    ... Unable to create channel of type 'ZAP' (cause 34 -
        Circuit/channel congestion)
    == Everyone is busy/congested at this time

This is triggered by lines in extentions.conf such as:

    exten => _X.,1,Dial(ZAP/g1/${EXTEN},,W)

The system is CentOS v5.2 with Asterisk 1.4.23  
(druid-asterisk-1.4.23.1-2), a Sangoma A104 4-port card, Wanpipe  
v3.4.4 and Zaptel v1.4.12.1. The system is attached to a single  
EuroISDN PRI and is located in the Netherlands.

Besides the above error, I also noticed this:

    CLI> pri show span 1
    Primary D-channel: 16
    Status: Provisioned, Down, Active
    Switchtype: EuroISDN
    Type: CPE
    Window Length: 0/7
    Sentrej: 0
    SolicitFbit: 0
    Retrans: 0
    Busy: 0
    Overlap Dial: 0
    T200 Timer: 1000
    T203 Timer: 10000
    T305 Timer: 30000
    T308 Timer: 4000
    T309 Timer: -1
    T313 Timer: 4000
    N200 Counter: 3

The status needs to be "Provisioned, Up, Active."

Following Sangoma's instructions for debugging an Asterisk PRI span, I  
can confirm that there are only outgoing frames and that the D-channel  
messages in Asterisk are the same as what the Wanpipe drivers are  
seeing. So, assuming that my local telco (KPN Telecom) has activated  
the D-channel, what else could possibly be causing this problem?

Thanks,

Jaap

I would call KPN Telecom and ask them for help as well.
They will have much more sophisticated tools for debugging PRIs and also will
be able to check on their end if they see the D-Channel as up.
