If you read the sipura documentation, you'll note they tell you the
spa products will only support "one" g729 conversation at a time.
Supposedly, that's because of the heavy processing requirements associated
with g729 and the limited processing cycles in the spa products.

Use a different codec on the spa and things will work.
