Question, can a Duplicate Line Appearance of the original extension be added to one of the Side buttons on an SPA500 series phone?
In detail, if my SPA504G phone has a user extension of 201, this appears on the top button.
What I'd like to do is set the second button to show 201 as well for toggling between calls when a second call comes in as they are talking to someone on the first line.
Whenever I try to choose the same extension as the first button in CCA is tells me it is not allowed, "extension already set up on button one".
Thank you, Paul
Either method will require the same amount of Ephone-DN's. That is how it is licensed, not the exact amount of dialable numbers on the system. But, I think you should have plenty of DN's to make this happen.
CCA will not allow you to have more than one button with the same number, but it is possible to do in CLI. I know that this feature will work on the SPA525G phones, the 7900 series phones, and the Cisco IP Communicator softphone.
Here is a link describing how it is configured in CLI (will work with all of the IOS releases supported on the UC500 platforms):
As far as I know, this feature is planned to be added to CCA in the future.
In CCA, no, you cannot do this. But, you can do something a little bit different.
You could create a second different ext. CFB to this second extension. On that second extension, you could call forward to vm of the first extension by using the transfer to vm prefix. If the transfer to VM prefix is 6, the CFNA extension would be 6201.
