Probleme mit Faxübertragung zwischen 4638 und 4960

smolty · 6 Okt 2008

Hi!

Ich bin grade dabei unsere Asterisk von Digium Karten auf Smartnodes umzustellen.
Konkret geht es um:

-eine 4960 für den S2M zum Amt
-eine 4114 um ein Faxgerät und evtl. später Modems anzuschließen
-eine 4638 für ISDN Einwahlen und Faxserver

Verbunden sind die Smartnodes über einen handelsüblichen No-Name Gigabit-Switch.

Telefonie und ISDN Einwahl laufen bisher wirklich schmerzfrei!

Probleme bereitet mir allerdings die Faxübertragung zwischen 4960 <-> 4638.
An der 4638 hängt ein Hylafaxserver mit einer Eicon Diva.

Das Faxprotokoll meiner Wahl wäre eigentlich T.38.
Ist meiner Meinung nach eigentlich die sauberere Lösung und sollte zwischen 2 Smartnodes wohl auch funktionieren.
Wie man sieht habe ich auch schon mit einige T.38 Parametern (dejitter-max-delay,redundancy,detection,ced-retransmission) experimentiert.
Allerdings ohne Erfolg :-(

Mittlerweile kommen hier keine Fax mehr an und es passieren seltsame Dinge zwischen 4638 und der Eicon.
Hier im Divalog sieht es so aus als würden für ein Fax ingesamt 3 B-Kanäle geöffnet?!

Und die Faxe kommen natürlich am Hylafax nicht sauber (sondern leer) an. :-(

Im /var/log/hylafax/capi4hylafax steht:
Fax received and calling '/var/spool/hylafax/bin/faxrcvd "recvq/fax05638.tif" "faxCAPI12" "00017341" "Connection was established but no fax data was received." "+49.XXXX.XXX.XXX " "" "270"'.

Habe bisher mit "debug gateway sip ..." und "debug media-gateway all" versucht dem ganzen auf die Schliche zukommen.
Hat leider alles nix gebracht.
Falls mir jemand einen Tipp geben könnte wär ich wirklich sehr dankbar!

Der aktuelle Stand ist:

Nachdem ich auf der 4960 noch die Taktquelle angegeben haben tritt das Problem nur noch selten auf. Kommt aber leider immer noch vor :-(

PHP:

system
  clock-source 1 e1t1 0 0

Ich wäre für jeglichen Input sehr dankbar...
