Outbound calls call quality

#1
Hi
Apologies if in wrong forum - was not sure which one to use...

I have an issue with my voipfone service which i'm hoping for some advice.
Incomming calls - no issue with the call quality at all. I can hear and can be hear with no snap, crackle or pop on the line.
However if i make an outgoing call it is a different story. First of all i can hear chronic distortion on the 'ringer noise', and when the call is answered it is so fuzzy and distorted (both ways) that a conversation is impossible.

I tweaked my codec settings a while back because we have a fairly weedy BB connection most days.
Currently my SNOM370 has the following settings on the RTP page.

Codec 1: GSM FR
Codec 2: GSM FR
Codec 3: G.722
Codec 4: G.726-32
Codec 5: GSM FR
Codec 6: G.729A
Codec 7: G.723.1
Packet Size: 20 ms
Full SDP Answer: on
Symmetrical RTP: off
RTP Encryption: on
Dynamic G.726 payload: on
SRTP Auth-tag: AES-32

Can provide other settings if required

Thanks

Do you see this issue on all calls or just international calls, for example?

Please call 152, how is the quality there?

Please try connecting the phone directly to your router with a different network cable to the one being used now. Disconnect everything from the network leaving just the one telephone. Do you still have quality issues?
