Re: [Freeswitch-users] Freeswitch as a SIP client

29 Sep 2016

      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.

Hello Dieter,
sure this should work. Registering a Freeswitch as a SIP client to an
external SIP server can be done through a gateway definition, as you
pointed out. The first step is to see, if the gateway is registered to
the Hipath ("sofia status" should show REGED for the gateway). If yes,
you're almost done. (I assume, you have to register to the Hipath, right?)
I think, that Freeswitch does not offer Subscribes in the external
profile, only in the default internal profile.
Do you receive an INVITE from the Hipath? Also note, that Freeswitch's
external profile is on Port 5080 instead of 5060, so Hipath has to send
to 5080.
On Linux, you may use ngrep to grep the SIP traffic: "ngrep -d any port
5080 -W byline").
Best regards
Peter

Hello,
this is my problem:
I would like to use Freeswitch as a gateway between our Hipath PBX and
an external SIP provider.
For that I created a Hipath SIP account that is working (tested with
X-lite). Now I would like to let Freeswitch act as a client using this
SIP account. Whenever there is an incoming call Freeswitch should act on
it and forward this call to an external SIP provider.
Is this possible? Does that make sense? Are there alternatives?
At the moment I'm stuck to configure Freeswitch as a client. I added the
Hipath SIP account as a gateway. When I compare the SIP traffic of
X-lite and Freeswitch using Wireshark I found out that Freeswitch dows
not offer the 'Subscribe' option. Is this the reason why it fails?
Can you help me?
Thanks in advance.
Dieter
