Large packets might be okay if your objective is simply to send maximum
data with the lowest overhead. But, if there is any mix of traffic at all
on the wireless facility, small and more frequent packets will provide
better response to multiple sessions/applications/users.

I have a client that is running asterisk over commercial wireless serving
approximately a ten mile radius using Breezecom equipment. Asterisk works 
very well with no modifications at all using sip and iax. Played with all
codecs, and all work well.
