Have you tried to file a JIRA in case it's a bug? As an alternative, have you thought of using Kamailio as the FS gateway, and then have Kamailio handle all the gateway stuff... (so to your provider, the UAC would be K and not FS)...

Hello guys,

I know this is kamailio's mailing list, but I'm getting no answer on freeswitch, and i thought someone here has probably done this is the past.

I have a proxy in front of freeswitch. I want freeswitch to use the proxy for everything including the termination to my provider.

If I configured the gateway like this:

<include>
<gateway name="myprovider">
<param name="username" value="username" />
<param name="auth-username" value="username"/>
<param name="password" value="password" />
<param name="register" value="true"/>
<param name="caller-id-in-from" value="true"/>
<param name="from-domain" value="myprovider.com"/>
<param name="realm" value="myprovider.com"/>
<param name="register-proxy" value="myproxy.domain.com"/>
</gateway>
</include>

The registration works properly, the REGISTER goes to the proxy like

REGISTER sip:myprovider.com;transport=udp SIP/2.0

and the proxy forwards it fine, and registration works great.
But when i try to call via this gateway, the call goes STRAIGHT to the provider!

If, on the other hand, i configure my gateway as:

<include>
<gateway name="myprovider">
<param name="username" value="username" />
<param name="auth-username" value="username"/>
<param name="password" value="password" />
<param name="register" value="true"/>
<param name="caller-id-in-from" value="true"/>
<param name="from-domain" value="myprovider.com"/>
<param name="realm" value="myprovider.com"/>
<param name="register-proxy" value="myproxy.domain.com"/>
<param name="proxy" value="myproxy.domain.com"/>
</gateway>
</include>

Registration does NOT work, because the uri is:

REGISTER sip:myproxy.domain.com;transport=udp SIP/2.0

Because there is no registrar on that proxy!
