Problem mit D-Channels

[VOIPdani]

Hi!

Ich nutze seit kurzem eine octoBRI von junghanns und habe folgendes Problem: Wenn ich * starte kommen folgende Warnings:

*CLI> Oct 12 10:08:57 WARNING[6042]: chan_zap.c:7545 zt_pri_error: PRI: !! Got S-frame while link down

Nun habe ich ein paar Fragen:
1) Was bedeuten diese Warnings?
2) Wie bedrohlich sind diese Warnings?
3) Könnten diese Warnings zu Errors werden?
4) Wie kann ich diese Warnings wegkriegen?
