Problem von chan_capi_cm mit dem Abweisen von anrufen?

[Hupe]

Aufbau:

Mein Asterisk hängt am internen S0 der Tk-Anlage mit einer FritzCard. Ich nutze chan_capi_cm 0.5.4.
Wenn ich das System als ISDN-Gateway nutze und einen eingehenden Anruf abweise (der Client ist diax) dann ist bei mir Asterisk in 4 von 5 Fällen in die Binsen gegangen. Das ist natürlich auch mal ne Art Asterisk zu beenden, aber irgendwie kommt da bei mir keine Begeisterung auf .

für die, die davon was Verstehen, hier ein Capi-Debug:

Vielleicht könnte das von Euch mal jemand Testen, ob das Problem nicht nur auf mein System beschränkt ist.

Hier hast du offensichtlich einen weiteren Fehler im Call-handling von chan_capi-cm 0.5.x gefunden. Dies sollte schon laenger im CVS (demnaechst 0.6) gefixt sein.
Koenntest Du das mal testen?

Ach mann! Ich dachte ich hätte jetzt was neues gefunden

Nee, aber mal i ernst. Klar kann ich das testen. Braucht nur etwas zeit, da ich noch ein paar meter config-Dateien mitändern muss....

Melde mich dann hier wieder.

Begreife ich nicht. Der Kontext ist auf jeden Fall existent.

Außerdem scheint es so zu sein, dass capi nichtmehr mit "conrt1" im Dial-Befehl arbeitet. Dafür tut es "ISDN1". Oder es klingelt, man nimmt ab, aber am Hörer ist stille, und am Client klingelt es weiter.

Fall2:
Ok, kann ich jetzt nicht liefern. Hatte Asterisk neu gestartet. Jetzt geht es auch mit "contr1". Hatte allerdings nichts geändert. Muss sowas wie "die Hand Gottes" gewesen sein...
Ich teste das Morgen mal weiter. Vielleicht geht es ja morgen (nicht)

 

[armincm]

Danke, deine Logs helfen mir schon mal weiter. Das mit dem 'contr1' kann ich mir nicht so einfach erklaeren, denn der controller wird gefunden. Es aber wohl kein Interface (Kanal) frei... Hmm, vieleicht ein Folgefehler...

Aber das mit dem ankommenden Ruf liegt daran, dass deine Telefonanlage keine SETUP Message schickt und ohne diese wird der Call nicht in Asterisk signalisiert (das ist neu in chan_capi). Das muss ich mal genauer untersuchen.

Anstelle von SETUP wird bei der Anlage ein 'Sending Complete' geschickt. Ich habe es nun auch in chan_capi eingebaut. Falls das anonymous-CVS noch nicht in sync ist, hier der Patch:

Hab das File mal gepatcht. Die Debug-Ausgabe sieht auch schon irgendwie besser aus. Es macht sich alerdings am hörer nur Stille breit (sprich, es passiert nix).

Das liegt an DISA(), denn DISA macht zwar ein Answer(), aber Asterisk schickt dieses Answer() nicht weiter (an CAPI), da der Kanal noch nicht im RING-mode ist.
Ich bin zwar der Meinung, dass Asterisk hier nicht korrekt arbeitet, denn Answer() sollte auch ohne Ring-mode gehen... aber egal. Setze einfach ein
exten => xxx,y,Ringing()
vor das DISA()

Ok, so scheint es zu klappen: Beim abweisen von Anrufen hängt sich Asterisk nichtmehr auf. Anrufe über Capi werden angenommen, und der fehler mit "contr1" ist auch nichtmehr aufgetreten. war wohl wirklich irgendwie ein Folgefehler).
Vielen Dank erstmal. Wenn ich noch irgendwo einen Fehler finde, dan Melde ich mich wieder (was ich aber nicht hoffe).
