I'm guessing that since the incoming call is PCMA (you're on EuroISDN, 
right?) that greater preference is given to PCMA as the codec to use on 
the leg of the call to the SNOM.  Notice I said guessing -- I really don't 
know if chan_capi works that way, but it sounds reasonable to me...

You can do something: you can remove allow=alaw from the codec list for 
your SNOM.  Granted this will affect your use of PCMA for your internal 
calls...  If it really annoys you you will need to check out how * decides 
the codec to use when it's bridging from one technology to another and 
change it.

If you're happy to use PCMA for your internal calls, why worry about it 
for chan_capi?  You're not paying for this bandwidth :)  If it's happening 
with incoming calls on other technologies, I think you need to look at 
how you specify the codecs for those other links (IAX or SIP provider).
