asterisk users - Aug 2012 - Incompatible voice frame ulaw/alaw

Hi list!

When I receive an incoming call from a SIP peer where I've configured

disallow=all
allow=alaw
(and no other codec)

I can see the following NOTICE on the console:

Dropping incompatible voice frame SIP/peer07-0000007c of format ulaw 
since our native format has changed to (alaw)

My question is: where can I change the native format from ulaw to alaw 
(or something else)? Is ulaw, as the native format, adjustable in some 
config file or is it hard-coded into Asterisk?

It doesn't seem to have any effect on the voice quality but the messages 
on the console are quite annoying.

PS: The peer doesn't support ulaw.

PPS: Asterisk 10.7.0

Thanks a lot!
Markus
