If I can use the full available band or if I can download exactly 50Mbs? The answer to the first question is: YES! That's why I use a traffic shaper... ;) The answer to the second question is: NO. I made a speedtest right now and I get only ~18Mbps download.>> Last but not least: I tried calls via Skype and WhatsApp (with my phone >> in my WLAN).

As soon as I use DT (configuring the phone to connect directly to the server) both partners can hear the "interruptions"... Thanks Luca Bertoncello (lucabert at lucabert.de)

I checked the xDSL-statistics of my DSL-Modem (which use the BananaPI to establish the PPPoE connection): adsl: ADSL driver and PHY status Status: Showtime Last Retrain Reason: 2 Last initialization procedure status: 0 Max: Upstream rate = 1709 Kbps, Downstream rate = 19888 Kbps Bearer: 0, Upstream rate = 1626 Kbps, Downstream rate = 20113 Kbps Bearer: 1, Upstream rate = 0 Kbps, Downstream rate = 0 Kbps So it seems, that my connection is about the half of the theorical one... I think, I must call Deutsche Telekom, but since I'll change my contract at 18.06., I'll wait some days. Then I'll have a "business" contract, and I hope I don't must speak with someone that can just say "you have to reboot your Fritzbox. What? You don't have a Fritzbox? That's not possible. Please check your Fritbox, I can't reach it"... ;) Bye Luca Bertoncello (lucabert at lucabert.de)

In which sense this is "significant"?Because if/when the Thomson is registered directly to DT, then Asterisk is not doing anything on the Banana. The fact that you get the problem with the Thomson registered directly to DT, but with the traffic still going through the Banana, indicates to me that "Asterisk running on the Banana" is not the problem.> > Can you get the full 50Mbps through the Banana when you're doing a > > download of something biggish? > > What do you mean now? If I can use the full available band or if I can > download exactly 50Mbs?I don't see the difference - I'm asking whether the Banana can manage to route 50Mbps of traffic.> The answer to the first question is: YES!

As soon as I use DT (configuring the phone to connect directly to > the server) both partners can hear the "interruptions"...Right. I'm very much agreeing with you here, that DT appears to be the problem, and I think Jeff's suggestion / offer to capture the audio data and do an analysis on it would likely show that. Just one suggestion regarding that: I recommend doing two packet captures; one with Asterisk registered to DT and the Thomson registered to Asterisk, and the other with the Thomson registered to DT but the traffic still going through the Banana.
