I have setup one jabber server running along the Freeswitch on the centos 5, and setup the gtalk in public context as the jabber server component on port 5347 , and established the federation with googletalk network. Now I can call from gtalk client to my sip account on freeswitch without problem by the following dialplan:

<extension name="jingle2sip">
<condition field="source" expression="mod_dingaling"/>
<condition field="destination_number" expression="^conf\+([^\@]+)\@(.*)$">
   <action application="bridge" data="sofia/default/$1%192.168.1.253"/>
</condition>
</extension>

where 192.168.1.253 is the ip address of freeswitch.

but I am having issues with the sip2jingle call.

in the default context dialplan, I can do this

<extension name="sip2jingle">
<condition field="source" expression="mod_sofia"/>
<condition field="destination_number" expression="^1500$">
   <action application="bridge" data="dingaling/jabber.mydomain.com/mybuddy@gmail.com"/>
</condition>
</extension>

where the jabber.mydomain.com is the component profile name I defined for the gtalk server component.

but if I modify the dialplan to do more general sip2jingle call as below:

<extension name="sip2jingle">
<condition field="source" expression="mod_sofia"/>
<condition field="destination_number" expression="^jingle\+([^\@]+)\@(.*)$">
   <action application="bridge" data="dingaling/jabber.mydomain.com/$1@gmail.com"/>
</condition>
</extension>

or
<extension name="sip2jingle">
<condition field="source" expression="mod_sofia"/>
<condition field="destination_number" expression="^jingle\+([^\@]+)\@(.*)$">
   <action application="bridge" data="dingaling/sip+${sip_fromuser}@${sip_fromhost}/$1@gmail.com"/>
</condition>
</extension>

I tested with jingle+mybuddy.lastname@gmail.com from my extension 1000 on soft phone Bria 2.2 on XP, I got the error "1000@gmail.com not found"

Could you guys share the correct syntax for doing SIP to Jingle calls?

Thanks,

Chris
