40ms isnt that big of a deal.... The only compelling reason I have found to increase much more then that is for vsat links and those are moonbounce delays anyway ;)

Re: [Freeswitch-users] IAX and CDR Trunking doesn’t save that much bandwidth when it comes down to it... You can achieve the same effects on freeswitch by adjusting the ptimes...
Example: G.711u at 20ms packetization uses 80k/sec... G.711u at 40ms only uses 72K/sec a 10% bandwidth savings...
To be fair, you've picked a man of straw: the figures for G.729 are much more compelling, unless you're prepared to put up with moonbounce-esque delays.
