I'm having issues getting the caller ID of the inbound call display once forwarded to a cell phone. I have read that RFC3325 (P-Asserted Identity) under "Remote Party/Privacy Indication" in the trunk settings is how this is done...? But when I have this setting on the trunk, I can receive inbound calls but outbound calls fail. The only way I can get the trunk to make outbound calls is to set the trunk in the "Remote Party/Privacy Indication" setting is "No Indication", "Remote-Party-ID" or "RFC3325 (Custom)".
I also read that maybe I need to add "header" info in the SIP address to make this work. If that is the case, I'm lost on what needs to be done.
Anyone else know where to go from here?
