I am currently using the following setup:
Snom 300 – Asterisk 220.127.116.11 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).
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
