Figure 16: G711
This topology fully based on G711 does not contain any compression.
This configuration is supported but requires a large bandwidth on WAN (no Voice compression).
In this example G711 is permanently used whatever the call destination is (intra-node or extra-
node).

Figure 17: G729
This topology based on G729 allows compression ON wan for MIPT 300/600 sets.
(MIPT set only supports G711 and G729, but not G723).
Generic rules:
- The OXE Network must be homogeneous in G729
- G729 must be set on all OXE nodes,
- When compression is required (for instance on WAN), G729 must be used by both MIPT & IP Touch sets.
