Complexity 5 is insane overkill. The default is 2 and should be left as
it unless you really see a need to change it. Complexity 1 is fine if
you're strapped for CPU and 3 can be OK if you can afford it.
More than that is just plain silly for anything real-time.

Okay I've got to admit I was probably ignorant on this; I just used
the same value for both quality and complexity settings, not knowing
what this actually do.

Have you tried also speex Narrowband "on device" on Symbian Nokia 3rd 
edition devices with pjsip?
