When exiting a nether portal after being teleported, the sound travel.ogg does not play. This was recently fixed on PC (see MC-233, note only the bit relating to this sound not playing was fixed) and as such should be fixed for pocket edition as well.
It appears that this request was misunderstood; the sound effect that should play when the player is standing inside the portal block (trigger.ogg) now plays when the nether is loading. The sound that should play when the nether is loading (travel.ogg) does not appear to exist in-game yet.

I can confirm that this sound is missing from the game. However, as it is not in the game files, it might be considered a feature request.
