mISDN Channel blockiert

[konabi]

Hallo,
ich verwende Asterisk 1.2.21.1 mit freepbx 2.2.2 und misdn-1_4_4

Im Asterisk ist eine Beronet BN4S0.

Die Karte ist mit einem Port an einen PTP angeschlossen.

nun habe ich festgestellt daß in regelmäßigen Abständen keine Anrufe über ISDN uns erreichen.

Eine Überprüfung ergab, daß ein ISDN Channel nicht freigegeben wird:

FreePBX*CLI> misdn show channels

  --> capability: Audio 3.1k
  --> echo_cancel: 1
  --> notone : rx 0 tx:0
  --> bc_hold: 0

/var/log/asterisk/full zeigt folgendes:

Danach hilft nur noch ein Neustart des Asterisk.

Ich bin für jeden Hinweis zur Fehlersuche dankbar.
