AstPligg has a link to a Panoramisk article on IAX2 trunking.
Excerpt:
Voice transport should always balance between real time and bandwidth consumption. When interconnecting two PBX in order to exchange more than one communication, it could be interesting to limit bandwidth consumption by carrying more voice samples in the same IP frame. This is what the Asterisk Inter Exchange protocol (aka IAX) is doing and gains are real.
Usually codec’s output is carrying 20 ms of voice. This value is efficient enough to allow a low jitter and low delay during transport. Depending on the codec used those 20 ms of sound represent a variable size to transport in the IP frame (generally using UDP and RTP). Since we can potentially transport more than one voice sample in an IP frame we can make some savings.
