i4b-L2 ... i_queue full or no fifo translator (Asterisk chan_capi)

[Thomas Zimmermann-7]

Hi all,

I use Asterisk with CAPI on FreeBSD 7 and Nagios only for sending and (later) receiving SMS alerts over ISDN to and from mobile users. Receiving SMS is an option to acknowledge or delegate alerts. Now I have stumbled across three issues.

1. Sharing Asterisk on the same NT with an existing PBX:
We have an ISDN line with 4 NTs (8 BRI channels) and 100 telephone numbers for DDI. The protocol is point-to-point.
Since connecting Asterisk behind the existing PBX is not possible, I share one of the NTs with the existing PBX.
I assume that the existing PBX listens to all DDI Numbers. How can I configure Asterisk to listen to one number without interfering with the other PBX?


2. I am still confused as to how I should setup capi.conf and extensions.conf correctly for an ISDN line with DDIs! All documentation I have found (readmes and Google) mainly focuses on ISDN with point-to-multipoint (msn).
Although my configuration works, I see strange behavior. After running Asterisk for about 15 minutes, the /var/log/messages log file and the console fill up about five times every second with the following message:
i4b-L2 dss1_pipe_data_req: unit=0, pipe=0, i_queue full or no fifo translator!!
I can stop this message using '/usr/local/etc/rc.d/asterisk stop'.
You can see my configuration files further down in this mail.
Do I have to set more parameters in my configuration, or should I replace my (passive) ISDN interface with an active one?


3. Sending SMS, the command above runs successfully, and I receive a message on the mobile phone. However, it displays the wrong ?Calling Line Identification (CLIP)?: It shows the main number instead of the DDI extension.

smsq --motx-channel=?CAPI/ISDN1/0622100000' 079xxx8690 'Hello World? (valid for Swisscom in Switzerland)

Hi,

There is a tool called "isdndecode", which you can run like:

isdndecode -u 0 -i -o -x

It will dump all the contents of the D-channel. Maybe you will find some error
messages there.

If you are using P2P you should maybe add the "power_on" feature to your
config:

isdnconfig -u 0 power_on

It will disable ISDN power saving.

Does the following message only appear when you re-start asterisk ?

i4b-L2 dss1_pipe_data_req: unit=0, pipe=0, i_queue full or no fifo
translator!!

Thank you Hans Petter!

I found out the message above appears only if asterisk is running and calls
are established with the other PBX mostly during office hours.
i4b-L2 dss1_pipe_data_req: unit=0, pipe=0, i_queue full or no fifo
translator!!

If the message appears I will check again with:
isdndecode -u 0 -i -o -x
asterisk -rvvvvvv and 'capi debug'

How can I set the commands permanently?
isdnconfig -u 0 -p DRVR_DSS1_P2P_TE
isdnconfig -u 0 power_on

Do you have some hints for capi.conf, extension.conf and smsq?
 
regards, Thomas

Hi Hans Petter

In the meantime, I noticed there is no correct way how to operate two ISDN
devices (asterisk + pbx) on one ISDN line in p2p mode. Of course its
point-to-point and not point-to-multipoint! Special thanks to Mathej
Ondrusek and David Wetzel for this information.
