Is anyone using the g.729 codec from digium (or synapse-global) on their asterisk boxes? Per channel pricing is about $10 btw: I picked up a few of those nortel 1535 h.264 wireless video sip phones from ebay. I paid the $49 + $8 shipping -- works quite well with asterisk. :-) Someone else is advertising them on ebay for, like $220+ Dan.
