[Asterisk-Users] I cannot use G711 (ulaw|alaw)

[Androtech]

Dear all,

I'm trying to use ulaw and alaw with Diax and Asterisk but I'm not able to, 
I got the following error message:

Mar 20 11:47:59 NOTICE[7099]: chan_iax2.c:6350 socket_read: Rejected connect 
attempt from 192.168.0.55, requested/capability 0x8/0xc incompatible with 
our capability 0xfe02.

I do not understand why because my Asterisk box load these codecs properly!

Does somebody know why?
