RTP da, aber nicht hörbar, unter Umständen

Hallo,

 

habe hier ver. 5.0.5 hinter NAT mit 3 Extensions: 1x snom 300, 1x Gigaset C475 IP, 1x C610A IP und Trunks zur DTAG und Sipgate.

Alles läuft seit über einem Jahren prima, bis sich bei ver. 5.0.3 ohne Änderungen am C475 IP plötzlich folgendes Verhalten zeigte:

 

Calls vom C475 IP nach extern lassen mich weder das Rufzeichen noch den Gesprächspartner hören;

Calls vom C475 IP nach snomone-intern verlaufen normal;

Transferiere ich ein zuvor vom snom 300 nach extern aufgebauten Call zum C475 IP läuft es ebenfalls normal;

Calls zum C475 IP von ex- oder intern verlaufen ebenfalls wie gewohnt.

 

Kurz, alles bis auf den externen Call vom C475 IP läuft wie es soll.

 

Habe die Traces für einen externen Call vom snom 300 mit dem vom C475 IP verglichen und keine relevanten Unterschiede erkannt; ohne aber ein SIP Profi zu sein.

Mit wireshark telephony analyse sehe ich, das selbst der RTP Stream zum C475 IP vorhanden ist und im player des wiresharks auch hörbar ist.

Welches Mobilteil ich am C475 IP benutze ist egal, stets das gleiche Ergebnis.

 

Mein Backup der ver. 4.5.0.1090 zeigt gleiches Bild.

Am C610A IP und snom 300 läuft alles wie gewohnt.

 

Beide pcap's wären bei Interesse verfügbar.

Kann jemand helfen?

 

Gruß...

Da es sich bei der PBX um einen B2BUA handelt, sollte man eigentlich ausschliessen können, dass irgendwas vom C475 auf den Trunk "durchschlägt". Klappt es denn wenn das snom sich auf der Extension von dem C475 registriert? Vielleicht liegt es einfach daran, dass das C475 auf CLIP steht und deswegen der Trunk-Provider streikt.

So sieht der RTP debug log des C475 IP aus:
