If I call from IP phone to IP phone I only see the number. If I set the name explicitely using "callerid = asrevieved" in my sip .conf or if I use SetCallerID(${CALLERIDNAME}) I get "aseterisk" on my display. IAX calls seem to go OK.

Could be the phone, some phones dont do Alpha characters, the 
Grandstream for example can not display the name, only the number.
