I am trying to call from one internal phone to another internal phone - but I can not get it working :(. I have an analog phone connected to a Digium TDM400P and an IP phone (identified as user:5) In directory.xml I have identified the IP phone as: <user id="5"> <params> <param name="password" value="5"/> </params> </user> In my dialplan I have: <extension name="Internal-5"> <condition field="destination_number" expression="^5$"> <action application="bridge" data="sofia/${sip_profile}/5% ${sip_profile}"/> </condition> </extension> In sophia.xml I try to make it so that sip phones have to register by having: <!--<param name="accept-blind-reg" value="true"/> --> <param name="auth-calls" value="true"/> <param name="auth-all-packets" value="true"/> When I dial '5' on the analog phone I can see that freeswitch tries to make the connection, but can not: [NOTICE] switch_core_state_machine.c:134 switch_core_standard_on_execute() Execute bridge(sofia/${sip_profile}/5% ${sip_profile}) [DEBUG] switch_core_state_machine.c:158 switch_core_standard_on_execute() Expanded String bridge(sofia/192.168.0.4/5%192.168.0.4) [WARNING] mod_sofia.c:1397 sofia_outgoing_channel() Cannot locate registered user 5@192.168.0.4 Any ideas/suggestions on how to call internal sip phones ?
