Hier mein Problem:

Nicht immer aber zu 50% im ausgehenden Anruf meldet sich die Gegenstelle dann bekomme ich nach ca 1 sek. die Meldung das der Anschluss vorübergehend nicht erreichbar ist.

Hier die Antwort der Telefongesellschaft:

Hello, we received your ticket regarding intermittent incorrect call behavior out to various numbers and were able to determine the cause of this call failure. Within the media information that is being negotiated by your device we are getting a "a=ptime:30" tag in the SDP we are receiving. This is a non-industry standard media setting that can cause a wide range of issues including the one that you've reported.

I'm not completely familiar with the device that your phone appears to be registering as, but I can say that this setting is commonly referred to as "RTP Packetization Interval" or "RTP Packet Size" within various models of devices. If you change this setting from "30" or "0.030" to "20" or "0.020" within your device that will correct the problems that you are reporting.


Thanks,

Hat jemand eine Idee das zu beseitigen?

Vielen Dank!

Mit dem FBEditor beim entsprechenden UserAgent Eintrag (ua1...20) von Nextiva in der Zeile "tx_packetsize_in_ms = 30;" auf 20 ändern.
