Posting this as a new question because I really could not think how to word a search.
We want to dial an extension and have the phone complete the call without having to press another key (Dial or Speaker) to complete the call.
Off-hook we can dial 720 and get extension 720. On-hook (speaker phone) we dial 720 then have to press the Dial or Speaker button to complete the call
Should be: On-hook dial 720 and after x seconds it should dial without pressing another key.
