Hello, I am currently using the following setup: Snom 300 - Asterisk 1.8.13.0 running on Raspberry Pi - Sipgate SIP Provider When I am using this setup, the call quality isn't as good as when using a direct connection like Snom 300 - Sipgate SIP Provider to my SIP Provider (Sipgate).
Sipgate supports > > - G.729 - ~ 12 kbit/s > - G.711 - ~ 100 kbit/s > - iLBC - ~ 15 kbit/s > - GSM - 13 - 20 kbit/s > - G.726 - 16 - 40 kbit/s > > According to my Asterisk server and sip show channels the used codec is 0x08 (G.711), so the best one possible. Still the quality isn't as good as on a direct connection between my Snom phone and Asterisk. Using Asterisk it feels a little bit like there is some more background noise or so. Any hints why the quality using Asterisk is less good than on a direct connection? Does Asterisk by default change anything on the signal or is it just passed through? Thanks :-) Best regards Stefan
