[Problem] Eingehender Gesprächsaufbau ist sehr langsam oder funktioniert gar nicht

[lelurch]

Hallo VoIP-Fanatiker,

bin leider auf ein neues Problem gestoßen. Der Aufbau von eingehenden Gesprächen braucht teilweise über 20 Sekunden, oder funktioniert gar nicht.
Habe mir dann das Protokoll via FritzCap und Wireshark aus der Fritzbox ausgelesen und gesehen, dass relativ schnell der SIP Request-Invite aufschlägt, jedoch die Trying und Ringing-Antworten ewig auf sich warten lassen.

Forwarded die Fritzbox zu langsam, oder stimmt da noch eine Einstellung nicht?
Muss ich evt. die Reaktios-/Ansprechzeit des Asterisken erhöhen?

Konfiguration wie folgt:
Einstellungen:

Fritzbox 7320
voip.cfg den Standardport auf 5062 gestellt
Forwarding von UDP 5060 & 5070-5079 & 7078-7109 & 9078-9109 & 10000-10100 auf Asterisken
4 Dect-Telefone, die sich als IP-Telefone am Asterisk anmelden.

Asterisk
Unter anderem 4 Extensions für die DECT-Telefone (Port 5062)

Alle Extensions und Trunks sind online

Ausschnitt Protokoll eines langsamen, aber geglückten Anrufs bis zur Annahme:

Hallo zusammen,

habe leider die Lösung selber nicht finden können. Also Fritzbox wieder in den Normalzustand gebracht, Asterisk auf den Port 5062 gestellt und der Fritzbox wieder die Hoheit über 5060 überlassen. Cron-Job, der nachts nach der Zwangstrennung einen SIP-Reload durchführt und seither läuft es. Evt. lässt sich die Fritzbox doch nicht ganz Ihre VOIP-Port Hoheit streitig machen....
