hi ... i have my gateway on 192.168.30.32 and a phone which connected to gateway 984432250161. I configured them like this : 1.created a xml file in \conf\sip_profiles\external with name cheap_tel.xml and the content is this : <include> <gateway name="provider"> <param name="proxy" value="192.168.30.32"/> <param name="register" value="false"/> <param name="caller-id-in-from" value="true"/> <!--Most gateways seem to want this--> <param name="username" value="not-used"/> <param name="password" value="not-used"/> </gateway> </include> 2.and in acl.conf added this node : <node type="allow" cidr="192.168.30.32/32"/> is my gateway config right ? because when i want to send a fax file by loopback with this command i have no error but fax is not saved in directory : Command ----> originate sofia/gateway/provider/984432250161 &txfax(C:/test.tiff) And also my dialplan configs for fax is this : <extension name="fax_detect"> <condition field="destination_number" expression="^984432250161$"> <action application="answer" /> <action application="set" data="transfer_ringback=${us-ring}" /> <action application="spandsp_start_fax_detect" data="transfer '9978 XML default' 10 ced"/> <action application="bridge" data="user/$1@${domain_name}" /> </condition> </extension> <extension name="fax_receive"> <condition field="destination_number" expression="^9978$"> <action application="answer" /> <action application="playback" data="silence_stream://2000"/> <action application="rxfax" data="$${base_dir}/faxes/${uuid}.tif"/> <action application="hangup"/> </condition> </extension> Can any one help me?
