Subject: [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
