Hi, There is requirement for me to add multiple sip gateways to Freeswitch, the first sip gateway uses the external.xml in sip profile to route traffic to Sip provider A. The second sip gateway will use a different UA to route traffic to Sip provider B. Here are my questions: 1. Do I need to create another external.xml with its own ip and port which point to the Sip Provider B? if that's case, what do I need to change in the sip profile external.xml file? 2. What is the rtp-ip and sip-ip in the external.xml file? Should that be the local IP of my sip server? 3. What do I need to change in my dialplan so that I can reference the Sip_Provider_B? an example would be good. External.xml <param name="sip-port" value="$${external_sip_port}"/> <param name="dialplan" value="XML"/> <param name="context" value="public"/> <param name="rtp-ip" value="$${local_ip_v4}"/> <param name="sip-ip" value="$${local_ip_v4}"/> <param name="ext-rtp-ip" value="1.2.3.4"/> <param name="ext-sip-ip" value="1.2.3.4"/> External/sip_provider_A.xml <gateway name="Sip_Provider_A"> <param name="username" value="xxx"/> <param name="password" value="xxx"/> <param name="from-user" value="03xxxxxxx"/> <param name="from-domain" value="x.y.z"/> <param name="auth-username" value="yyyyy"/> <param name="realm" value="bwas02.voip.izzz.zz.au"/> <param name="proxy" value="sipconnect.voip.zzzz.zz.au"/> <param name="register" value="true"/> <param name="register-transport" value="udp"/> <param name="context" value="public"/> </gateway> External/sip_provider_B.xml <gateway name="Sip_Provider_B"> <param name="username" value="aaa"/> <param name="password" value="bbb"/> <param name="from-user" value="03xxxxxxx"/> <param name="from-domain" value="x.y.z"/> <param name="auth-username" value="yyyyy"/> <param name="realm" value="bwas02.voip.izzz.zz.au"/> <param name="proxy" value="sipconnect.voip.zzzz.zz.au"/> <param name="register" value="true"/> <param name="register-transport" value="udp"/> <param name="context" value="public"/> </gateway> Cheers, Louie
