Hello,

I would like to forward did call to an extension. I'm sure that what i did is correct because it generates an erroo like: cannot create outgoing channel of type USER cause User is not registered.

1) I've created as user related to the did in /directory/default.xml

2) made chenge in Local_extension, contion field= ${sip_to_user} expression=my_did

3)added an extension related to my_did  in public.xml

Is that way i have to do to forward my call to an extension?

What is the difference between call forward and call transfer?

Thank you
