Fritzbox 7270v3 als SIP-Registrar - keine Verbindung zu Softphone

[JohnDoe42]

Hallo zusammen,

seit einigen Tagen versuche ich erfolglos, einige Softphones, welche per LAN an die Box angeschlossen sind, über die Festnetztelefonie zu erreichen.
Zur Konfiguration: In der Box sind einige Telefonnummern (uas) registriert und aktiv. Einige von diesen sind am S0-Bus befindlichen ISDN-Telefonen zugewiesen, andere zwei Geräten an den analogen Ports. Die Telefonie zu und von diesen Geräten funktioniert fehlerfrei.
Nun habe ich für die weiteren Nummern einige IP-Telefone in der Box eingerichtet, d.h. die Box fungiert als SIP-Registrar. Wenn ich nun "von außen", als beispielsweise mittels Handy, zu den angeschlossenen Softphones telefonieren möchte, schlagen die meisten Versuche (ca. 9 von 10) fehl.
Hier mal ein Paketmitschnitt des Verbindungsaufbaus:

Hat jemand einen Tip, wie ich die Ursache weiter eingrenzen kann ?

Abend

Du hast...

...dein Softphone so angemeldet?
Benutzer: 620
Registrar: fritz.box
Passwort: ********
...mehr nicht!

...und dein Mobile so?
Benutzer: 621
Registrar: fritz.box
Passwort: ********
Proxy: Dein.DynDNS.de
Lokal im WLAN brauchst du keinen Proxy, aber übers Internet.
Ein Softphone z.B. am Arbeitsplatz, übers Internet an deiner FB registriert,
würde dann auch mit Proxy konfiguriert.
Dafür wird in der Fritz!Box der Haken gesetzt...


Probiers einfach mal so.
Dann geht z.B. "internes" telefonieren:
**620 (Mobile --> Softphone) **621 (Softphone --> Mobile)

Hallo,

das war evtl. ein wenig mißverständlich: Ich hab' das Handy nicht am Registrar der Box angemeldet.
Ich habe einige Softphones an der Box angemeldet, welche übers Festnetz nicht oder nur in einem von zehn Fällen erreichbar sind.
Die Telefone, die an der Box am S0-Bus und/oder an den analogen Anschlüssen hängen, laufen alle einwandfrei.
Heißt: Alle Telefonnummern sind aktiv, allerdings diejenigen, welche ich den Softphones zugeordnet habe, sind mehr oder weniger nur zufällig zu erreichen. Ich werde nochmal den voipd mit -fv starten und die Logs durchgucken.
