Cisco ATA 187

Looking for the standards that would help to improve Cisco ATA 187 signal quality by impedance setting... The closest settings for Switzerland, I could find by googling is this http://en.wikipedia.org/wiki/Two-wire_circuit 270Ω + ( 750Ω || 150 nF ) to be verified tomorrow... by default Cisco sets 600 Ohms complex which seems to be oriented to North American market.

Cisco fuzzy voice

Cisco IP phone users are complaining about voice quality only on G.722 calls. Looking for the ways to improve it. There is this discussion, that comes close to what we experience: https://supportforums.cisco.com/message/3205941#3205941 Probably we should try to disable G.722 and downgrade G.711, as there are no control available for input gain in IP phone that probably is a source of "fuzzy" voice.
