I am in Text-Mode (Trunk). When i try to update your information the information wont stay. It will jump to the main Trunk when updating tab but at advanced-tag both fields will be empty. Tried different browsers already.
I already checked the code and only works on no text mode trunks (Only visual mode), we are updating the code to allow on any kind of SIP / PJSIP trunks.
For reference: P-Preferred-Identity and <sip:{CIDNUM}@{HOST}> working great when in normal-trunk-mode. Thanks for future fixing this in text-mode as well.
