Ok I got this one…just put ext-in-contact setting and then define the extension to be same as FromUser in my provider.xml in /conf/sip-profile/external/

  <!--/// extension for inbound calls: *optional* same as username, if blank ///-->

  <param name="extension" value="xxxxxxxxxx"/>

  <!--extra sip params to send in the contact-->

  <param name="extension-in-contact" value="true"/>

Subject: [Freeswitch-users] FS Registration Contact

Hi All,

    I have FS registered to an ITSP. The contact is showing as follows..

Contact: sip:gw+itsp@1.1.1.1:5080;transport=udp

Itsp is the name of the SIP gatway and its IP is changed to 1.1.1.1

I want the Phone number (FromUser)to show in the contact header in the REGISTER msg going to the ITSP.

How can I do that?

Thx,

Ujjval.
