Hi an alle,
ich habe folgendes Szenario bei einem Session Auf- und Abbau mit einem über den Asterix Server registrierten Client.
Hier einmal mein Auszug aus Packetyzer:
Obwohl wenn ich von dem Protokoll ausgehe alles korrekt scheint seht ihr, das nach dem 2ten Versuch einen neue Session aufzubauen ich ein Declined zurückbekomme, welches ich mir nicht erklären kann.
Vllt. findet ja jemand einen Fehler der mir nicht aufgefallen ist.
Gruß
Karsten
