Hi , I have subscribed to sonovoip a sip trunk provider who uses IP based authentication for SIP services , I am trying to make outbound international calls which are being rejected by the provider for some reason, I am not able to figure out if there is something wrong with the configuration. I am listing out my configuration. Any help would be greatly appreciated . I have also tried #wiki.freeswitch.org/wiki/Provider_Configuration:_SonoVoIP configuration from freeswitch wiki gives errors . The voip configuration works perfectly with asterisk 1.6 My configuration is follows Under /usr/local/freeswitch/conf/sip_profiles/external cat sonovoip.xml <include> <gateway name="sonovoip"> <param name="username" value="anything"/> <param name="password" value="anything"/> <param name="realm" value="x.x.x.x"/> <!--sonovoip ip --> <param name="register" value="false"/> <param name="caller-id-in-from" value="true"/> <param name="extension-in-contact" value="true"/> </gateway> </include> My dialplan , under /usr/local/freeswitch/conf/dialplan/public.xml <extension name="sonovoip" continue="true"> <condition field="destination_number" expression="^(00.*)$"> <action application="bridge" data="sofia/gateway/sonovoip/$1"/> </condition> </extension> I did change the vars.xml ports <!-- Internal SIP Profile --> <X-PRE-PROCESS cmd="set" data="internal_auth_calls=true"/> <X-PRE-PROCESS cmd="set" data="internal_sip_port=5080"/> <X-PRE-PROCESS cmd="set" data="internal_tls_port=5081"/> <X-PRE-PROCESS cmd="set" data="internal_ssl_enable=false"/> <X-PRE-PROCESS cmd="set" data="internal_ssl_dir=$${base_dir}/conf/ssl"/> <!-- External SIP Profile --> <X-PRE-PROCESS cmd="set" data="external_auth_calls=false"/> <X-PRE-PROCESS cmd="set" data="external_sip_port=5060"/> <X-PRE-PROCESS cmd="set" data="external_tls_port=5061"/> <X-PRE-PROCESS cmd="set" data="external_ssl_enable=false"/> <X-PRE-PROCESS cmd="set" data="external_ssl_dir=$${base_dir}/conf/ssl"/> The debug #pastebin.com/4MFhSWm9 Please advise if any other information is required.
