We have a UC520 user that is wanting to use the barge feature. The UC520 has shared ephone-dns that are configured as dual-line extensions. This customer has a 7975G phone, which I know is octo-line capable. This customer also has 7931G phones, which does not have octo-line support. The phone that he wants to use the call barge on is the 7975G phone, which has octo-line support. Can he barge in on the extensions that are not configured as octo-lines?
Will there be octo-line support for 7931G or SPA500 phones in the future?
