Nur ein B-Kanal nutzbar?

[nairolf86]

Hallo zusammen,
ein wirklich tolles Forum habt ihr hier, beschäftige mich nun doch schon seit ein paar Tagen damit und lese Beitrag um Beitrag, nur zu meinem Problem habe ich leider noch keine Lösung gefunden.

Verwende ein Debian mit Asterisk 1.4 und chan_capi 1.1.5 über USB angeschlossen an ein Siemens SX353 ISDN Telefon

Funktioniert auch alles soweit, nur die Nutzung beider ISDN B-Kanäle bereitet mir Schwierigkeiten.
Ich kann einen Anruf von einem Sip Phone nach außen über ISDN ganz normal aufbauen, von einem zweiten Sip Phone nur dann leider keinen zweiten, Asterisk legt dann sofort wieder auf.

Beide Sip Phones wählen über folgende Extension nach draußen:

;Sip-Phones rufen alles ueber ISDN an...
exten => _X.,1,Dial(CAPI/ISDN1/28***:${EXTEN},30)

Meine capi.conf:

Ich vermute den Fehler in der Gegend wo das Sip Phone 2000 die Antwort NOANSWER bekommt, versteh den Fehler hier aber nicht.

Das auflegen am Ende war dann ich.

Getestet habe ich schon so ziemlich alles was ich hier im Forum dazu gefunden habe: Wenn cih mit dem ISDN Telefon zwei Verbindungen aufbauen will funktioniert das, eine andere Sende-MSN hab ich auch schon getestet, gleiches Problem. Wenn ich von außen ein Sip Phone anrufe und dann mit dem anderen raustelefonieren will geht auch nichts. Ich bin mit meinem Latein wirklich am Ende
Hoffentlich kann mir jemand von euch helfen!

Hi,

ich nehme mal an, dass die erste Nummer (Vorwahl 0151***) die private Handynummer ist und die zweite Nummer (0892***) der eigene Festnetzanschluß ist.

Wenn dem so ist, sind schon beide B-Kanäle mit ausgehenden Telefonaten belegt und man kann sich dann natürlich nicht mehr selbst anrufen...

Grüsse
Thomas

Hi Thomas,
Danke für deine Antwort erst mal! Habs gestern elider nicht mehr geschafft noch zu antworten!
Okay das hätte ich erwähnen sollen, nein ich versuche nicht den gleichen Festnetzanschluss anzurufen. Der Anschluss mit der Nummer 0892*** ist ein eigenständiger analoger Anschluss!

Hat sonst wirklich keiner eine Idee? Ich hab inzwischen die starke Vermutung dass das SX353 einfach nur einen Kanal über USB bereitstellt. Teste das am Wochenende wohl mal mit einer PCI ISDN Karte.
