Rahmenbedingung:

• Telekom Call&Surf IP - Leitung
• Einwahl über Twinkle, direkt auf der IP des * Servers
• Nach eingabe der Pin erfolgt login, und MusicOnHold is zu höhren.

Ab dem Moment wo MOH zu höhren ist, läuft in der asterisk_cli (gestartet mit asterisk -c) folgendes ab:

Jeweils genau bei der Ausgabe "Difference..." ist dann eine Unterbreschung von 1-4 Sekunden. Also bei der Ausgabe von:

Difference is 15368, ms is 1941

Woran kann das liegen?
