Depends on if you have compression or not. G.711 is without compression and G.729 is with compression. The below is stolen from Cisco (don't hate me!)
I think only the top 2 rows apply in Mitel land...

There is a table in the eng guidelines for this but in short, depending on link type and packet rate between 80-120Kbps for G711 (uncompressed) and 20-80Kbps G729 (compressed) on the wire.
