Is it possible to “send back” the callername to the calling phone?
The SIP-phones have no internal phonebook, they use an xml-phonebook-app. So the phone call only the number, and in the redial list is only the number, not the name.
For incoming calls asterisk sets the CALLERID(name) … so the phone knows both name and number.
I’m looking for sending back the callername to the phone, for example when I dial 12345, asterisk should send back to the phone the name for this number 12345, so I can see at the phone the name also at outgoing calls and in the redial-list.
