I'm guessing 'does not ring' means it uses the earpiece for ringing instead of
the speaker. You will need stereoout.state for the ringing, then change to
voip-handset.state when answering the call. This is what is needed when
working with linphone, although the change of state is not automated yet.
voip-handset.state is in both FSO and SHR IIRC. You should be able to do the
state switch with an asterisk script.

For linphone I use Brian Code's asound.conf :
This uses dmix and dsnoop and gives stutter-free sound in both directions with
linphone. It does have echo since we can't use the suppression in the GSM
