asterisk users - Mar 2003 - Unable to set audio mode on channel 1 + ring after hangup + moh + echo

Hi
I use a Wildcard X101P as FXO and a phone connected to an ATA186 using 
SIP to connect to *.
phone ----- ata186 ----- * ----- X101P ----- pstn


On every call using the X101P I get
"Unable to set audio mode on channel 1" but I got no problem

Why sometimes after receiving a call the phone ring one time (only)???

This is the log of a standard call coming from outside

    -- Starting simple switch on 'Zap/1-1'
    -- Executing Macro("Zap/1-1",
"stdUsr|211|SIP/211&SIP/213") in new stack

What is the problem for the warning?

Third question, do I need a working soundcard to use music on hold?

I have a big echo on my side when talking using the fxo

(my zapata.conf)
;
; Zapata telephony interface
;
; Configuration file

[channels]
;of course we want to run the software echo canceller
echocancel=yes
echocancelwhenbridged=yes

language=en
context=out2in
signalling=fxs_ls
channel=1

callwaiting=yes
callwaitingcallerid=yes
threewaycalling=yes
transfer=yes
cancallforward=yes
;we can tune the gain on incoming and outgoing audio
;adjust these if you have a device that seems 'quiet' or 'loud'
rxgain=0.0
txgain=0.0

When compiling I use the
KFLAGS+=-DECHO_CAN_MARK2.

Thanks

This error is fixed in CVS.  While the error itself is harmless, some
other code that was included in the same patch could potentially cause
problems with echo and even possibly a segfault.
