I am using proxy authentication in my setup and it is working. To do this I have created an acl *autoload_configs/acl.conf.xml* <list name="opensips" default="deny"> <node type="allow" cidr="1.2.3.4/32"/> <node type="allow" cidr="1.2.3.5/32"/> <node type="allow" cidr="1.2.3.6/32"/> </list> *sip_profiles/external.xml* <param name="auth-calls" value="true"/> <param name="apply-proxy-acl" value="1.2.3.2/32"/> <param name="apply-inbound-acl" value="opensips"/> This is all working as desired. The problem is prior to adding the opensips I was using the network_addr variable in my dialplan. <extension name="tollfree_to_providerA"> <condition field="${acl(${network_addr} opensips)}" expression="true" break="on-false"/> <condition field="destination_number" expression="^(\+?1)?(8(00|44|55|66|77|88)[2-9]\d{6})$"> <action application = "set" data="dtmf_type=rfc2833"/> <action application="set" data="accountcode=customer1123"/> <action application="set" data="continue_on_fail=false"/> <action application="set" data="hangup_after_bridge=true"/> <action application="set" data="proxy_media=true"/> <action application="bridge" data="sofia/external/$2@8.7.6.5:5060"/> </condition> </extension> This of course no longer works because network_addr is always the address of my proxy server. How can I get the address from the X-authip into the dialplan?
