hello, My extension are working properly. But they can't send calls to gateway. I have 2 interfaces, one with public and another with private lan. Gateway is in private lan. Please suggest. My configurations are as follows: /conf/sip_profiles/external.xml: <param name="rtp-ip" value="110.4.12.111"/> <param name="sip-ip" value="110.4.12.111"/> <param name="ext-rtp-ip" value="auto-nat"/> <param name="ext-sip-ip" value="auto-nat"/> /conf/sip_profiles/internal.xml: <param name="rtp-ip" value="192.168.1.11"/> <param name="sip-ip" value="192.168.1.11"/> <param name="hold-music" value="$${hold_music}"/> <param name="apply-nat-acl" value="nat.auto"/> haven't made any changes in conf/autoload_configs/acl.conf.xml to route calls from providers, /dialplan/public/providers.xml: <extension name="provider"> <condition field="network_addr" expression="200.144.44.177"/> <condition field="destination_number" expression="^(\d+)$"> <action application="transfer" data="$1 XML context_AX"/> </condition> </extension> gateway is defined at /conf/sip_profiles/internal/gateways.xml: <include> <gateway name="gateway_AX"> <param name="username" value="admin"/> <param name="password" value="nepal123"/> <param name="proxy" value="192.168.1.100"/> <param name="register" value="false"/> <param name="extension" value="1001"/> </gateway> </include> To route internal calls from extensions, /conf/dialplan/default.xml: <extension name="my_internal"> <!--<condition field="${ruleset}" expression="internal" /> --> <condition field="destination_number" expression="^(d+)$"> <action application="bridge" data="sofia/gateway/gateway_AX/$1"/> </condition> </extension> to route calls from providers, conf/dialplan/inbound_routing.xml: <context name="context_AX"> <extension name="from_provider_to_AX"> <!--<condition field="destination_number" expression="^00(1.*)$">--> <condition field="destination_number" expression="^9(\d+)$"> <action application="bridge" data="sofia/gateway/gateway_AX/$1"/> </condition> </extension> </context> Please help.
