[Asterisk-Users] iLBC, Speex and X-Lite

[Michael Van Donselaar]

I've been trying out the newest X-Lite (Build 1012) with iLBC and speex
codecs.

If I enable only iLBC _or_ SPX on X-Lite and call the echo-test on my
asterisk server, the call connects, but I get no sound.

If I enable only iLBC _and_ SPX, X-Lite indicated that it has connected
with iLBC, and I hear a weird squawking.

My sip.conf contains:

allow=iLBC
allow=SPEEX
allow=gsm

I've heard that asterisk and kphone will work together using iLBC.  Does
anyone else have any interoperability experience?  Any ideas on what I
should do to debug this?
