you can set variables at the gateway level, and then they  are set as channel variables for inbound calls:

http://wiki.freeswitch.org/wiki/Sofia.conf.xml

<gateway name="gateway012">
   <param name="realm" value="sip.voipcarrier.com" />
   <param name="username" value="WBrandes" />
   <param name="password" value="myvoiceismypassword" />
   <param name="register" value="true" />
   <param name="caller-id-in-from" value="true" />
   <param name="ping" value="5" />
   <param name="ping-max" value="3" />
   <param name="retry-seconds" value="5" />
   <param name="expire-seconds" value="60" />
   <variables>
     <variable name="verbose_sdp" value="true"/>
     <variable name="absolute_codec_string" value="PCMU,PCMA" direction="outbound"/>
     <variable name="customer_id" value="3532" direction="inbound"/>
   </variables>
 </gateway>

Subject: [Freeswitch-users] How to set channel variable per SIP profile

Hi,

Subject says it all. Is there a way to set channel variable for all
calls passing through a SIP profile?

For example, I want all calls authorized with ACL and hitting SIP
profile to have country=foo. This has to be done before hitting the
dialplan.
There is a bunch of "params" in the SIP profile, but these aren't
channel variables.

Thanks!
-Victor
