my sip.conf add two account:

[123]
type=friend
username=123
host=dynamic
context=95040
dtmfmode=rfc2833
disallow=all
allow=g729
insecure=port,invite
canreinvite=no
nat=yes

[321]
type=friend
username=321
host=dynamic
context=95040
dtmfmode=rfc2833
disallow=all
allow=g729
insecure=port,invite
canreinvite=no

my extension is :

exten => 321,1,Dial(SIP/321)


when i want to set up a call (123 dial 321). but failed. it says:

 == Using SIP RTP CoS mark 5
[Aug 20 18:23:21] NOTICE[14543]: chan_sip.c:8454 process_sdp: No
compatible codecs, not accepting this offer!

Could you tell me what 's wrong?
