The user/ channel uses the dial-string param on the domain or the user to resolve the correct target to dial. So its like a pseudo channel... Which in the default configs it calls the sofia_contact api to get to the correct user. In your example below with the default config they will not differ in who to ring but in the default I set a variables on the originate line for presence. Example user/1001@$${domain} will expand this: <param name="dial-string" value="{presence_id=${dialed_user}@$ {dialed_domain}}${sofia_contact(${dialed_user}@${dialed_domain})}"/> dialed_user and dialed_domain are variables set inside the user/ endpoint when you call it. /b On May 19, 2009, at 1:48 PM, Larry Marshall wrote:

What are the differences between these two actions?

<action application="bridge" data="USER/1001@$${domain}"/> <action application="bridge" data="sofia/internal/1001%$${domain}"/>

Thanks, Lars
