[asterisk-users] Rusting Snoms?

[Tim Panton]

On further investigation - it may well be that the switch doesn't like  
the phones (or vice-versa)
I tried daisy-chaining one phone off the second port of the other and  
got distinctly better audio.

It's a new netgear fvs 318 with autosensing 100/10 ports.

Any clues ?

Thanks.
Tim
