[Asterisk-Users] BRIstuff/QuadBRI problem: Ring requested on unconfigured channel 255/255 span 5

[Bruno.Voigt at ic3s.de]

Hi all,

I'm running a stable Asterisk on a HP DL380G2 1.4Ghz 0,5GB RAM
equipped with 1x TE410P and 2xJunghanns QuadBRI running in NT-mode.

Connected to the BRI-Ports are 12 Fax-Modems (Elsa MicroLink ISDN/TL V.34)
which are only operating in dial out analog mode to deliver fax messages.

After a while of running fine (50-200 dial out connections)
on some S0 spans the following message occurs over and over again:

chan_zap.c:8009 pri_dchannel: Ring requested on unconfigured channel 
255/255 span 5

The Modems connected to this span get NO DIALTONE for every ATD.
Modems on other spans continue to operate.

This error seems to appear mostly on  span 5 and 6.

After restarting asterisk everything is okay again for a while.

Any hints about what is going on here are greatly appreciated ;-)

TIA, Bruno - bruno @ ic3s.de
