I dont know if it is significant or not, but my voice quality through 
teliax improved considerably when I switched from iax to sip.

I'm guessing that is because they can then do a handoff so that the 
audio path goes direct from your asterisk box to teliax's provider's 
softswitch.  If you use iax for voice, then the audio path goes to 
teliax's iax system which then forwards it to their provider's 
softswitch.  Going direct with SIP/rtp seems to mean less jitter, 
clicking, etc and is an all-round much better experience to my ear.

Amusingly, I don't seem to have the same problem with iax and sixtel.  I 
guess teliax's iax servers are just more heavily loaded.  Or teliax's 
iax systems and my asterisk box are out of version sync and are having 
a disagreement over jitterbuffer protocol or something silly like that.
