Hi all, I have an * installation with one AVM Fritz card, one TDM 40b and one sip phone. The problem i have is that when i place calls from the sip phone everything works fine. When i receive calls to the sip phone i cannot hear and the calling party cannot hear too. Is it a codec problem ? Here is my sip.conf. [general] port = 5060 ; Port to bind to bindaddr = 192.168.0.150 ; Address to bind to context = internal disallow=all allow=ulaw tos=lowdelay maxexpirey=3600 ; Max length of incoming registration we allow defaultexpirey=120 ; Default length of incoming/outoing registration notifymimetype=text/plain ; Allow overriding of mime type in NOTIFY ; [15] type=friend username=15 ;secret=blah host=dynamic defaultip=192.168.0.203 dtmfmode=inband ; Choices are inband, rfc2833, or info __________________________________ Do you Yahoo!?
