In my (limited) experience I've found softclients always produced poor
results (choppy lagged voice); CISCO-ATA and CISCO7960 however performed
perfectly and usually better than PSTN call quality.  I spent two hours
chatting to my friend in the US (I live in the UK) and he was stunned at the
end of the call when I told him it was a voip->pstn call via voicepulse.

A) Skype uses iLBC as a codec which Asterisk already has
B) Asterisk won't be adding latency on LAN->LAN, it's your end clients - try
Firefly - www.virbiage.com (insert bias comment here) and see if that's
addresses your issues.
