[Freeswitch-users] URI dialplan setup

[Mark Campbell-Smith]

Hi

Voip provider Ippi allow calls to/from skype users.  For me, this will work
quite well in my home pabx, and I do not want to implement the
SipThreeSkype solution.

I have created the gateway and successfully registered to Ippi's sip server
at ippi.fr.  Ippi requires that to dial a skype user, the following URI
format must be dialed: my-skype-address at skype.ippi.com. (this successfully
calls my skype address using a softphone)

I am trying to create a dialplan that will allow me to call a skype user
through the Ippi gateway.

This is my gateway setup (notice ippi uses ippi.fr):
<include>
  <gateway name="ippi.fr">
    <param name="username" value="username"/>
    <param name="password" value="password"/>
    <param name="proxy" value="ippi.fr"/>
    <param name="realm" value="ippi.fr"/>
    <param name="auth-username" value="username"/>
    <param name="register" value="true"/>
  </gateway>
</include>

I have the following in the dialplan:

<extension name="ippi-skype">
  <condition field="destination_number" expression="^5000$">
     <action application="set" data="call_timeout=90"/>
     <action application="set" data="hangup_after_bridge=true"/>
    <action application="info"/>
    <action application="bridge" data="sofia/gateway/
ippi.fr/my-skype-address at skype.ippi.com"/>
  </condition>
</extension>

Now I realize that according to the wiki, I should not put sofia/gateway/
ippi.fr/my-skype-address at skype.ippi.com (ie the @skype.ippi.com), but I
need a way to dial out through the ippi gateway (ippi.fr), but to a user in
domain skype.ippi.com.  I did try the two following options:
    <action application="set" data="sip_invite_to_uri=
my-skype-address at skype.ippi.com"/>
    <action application="export" data="sip_invite_to_uri=
my-skype-address at skype.ippi.com"/>

Wireshark gives me the following for a successful call using Jitsi
softphone:

Session Initiation Protocol

        Method: INVITE

            SIP from address: sip:username at ippi.fr
            SIP tag: 35bcc007
        To: <sip:my-skype-address at skype.ippi.com>
            SIP to address: sip:my-skype-address at skype.ippi.com

            Contact Binding: "username" <sip:username at 192.168.1.6:62110

        User-Agent: Jitsi2.5.5137Windows 7
        Content-Type: application/sdp
        Content-Length: 910

What do I use in the bridge statement so that it calls
my-skype-address at skype.ippi.com, using gateway ippi.fr?

Suggestions appreciated!
