[Freeswitch-users] Freeswitch as a SIP client

[Scholz, Dieter]

Hello,

thanks for your comment.

Perhaps I was a little unspecific. So here are some more details:

I'm a beginner concerning VOIP (I reached a state where I am able to 
connect VOIP endpoints, develop a dialplan and connect to an external 
provider) but a very experienced network and Linux user. Because I would 
like to learn Freeswitch from scratch I started with the minimal 
configuration of the Jessie distribution.

I added a gateway definition to the external profile (tried the internal 
profile, too - same behaviour):

<include>
         <gateway name="x">
                 <param name="realm" value="IP ADDRESS"/>
                 <param name="username" value="USERID" />
                 <param name="password" value="PASSWORD" />
                 <param name="register" value="true" />
         </gateway>
</include>

When I start Freeswitch a connaction attempt is made. A REGISTER is send 
to the HIPATH, a TRYING and then I receive an answer 404 NOTFOUND. If I 
use X-lite and connect to the HIPATH the connection attempt is 
successful. So the SIP account of the HIPATH seems to work.

My sofia.conf.xml is:

<configuration name="sofia.conf" description="sofia endpoint">
         <global_settings>
                 <param name="log-level" value="0"/>
                 <param name="tracelevel" value="DEBUG"/>
         </global_settings>
         <profiles>
                 <X-PRE-PROCESS cmd="include" data="../sip_profiles/*.xml"/>
         </profiles>
</configuration>

And my external.xml is:

<profile name="external">
         <gateways>
                 <X-PRE-PROCESS cmd="include" data="external/*.xml"/>
         </gateways>
         <settings>
                 <param name="sip-port" value="$${external_sip_port}"/>
                 <param name="auth-calls" value="false"/>
                 <param name="debug" value="0"/>
                 <param name="dialplan" value="XML"/>
                 <param name="context" value="public"/>
                 <param name="codec-prefs" value="$${global_codec_prefs}"/>
                 <param name="rtp-ip" value="$${local_ip_v4}"/>
                 <param name="sip-ip" value="$${local_ip_v4}"/>
                 <param name="ext-rtp-ip" value="auto-nat"/>
                 <param name="ext-sip-ip" value="auto-nat"/>
         </settings>
</profile>

The console says: Failed registration.

Any hints on what is missing? I looked up the vanilla configuration but 
there seems to be no promising additional options.

Thanks.

Dieter
